New Features

The following enhancements were added to ISM Revit Plugin 10.2.

Import of Reinforcing into Revit®

Reinforcing objects in ISM repositories are now imported into Revit when creating a new Revit model from an ISM repository and when updating Revit models with changes in an ISM repository. As with previous versions of ISM Revit Plugin, this release also supports the export of reinforcing from Revit to ISM. All types of ISM reinforcing are supported in the import. This enables productive workflows between Revit and products such as RAM Concept, where 3D reinforcing designed in RAM Concept can be transferred into Revit for 2D documentation and scheduling.

An overview video of this new feature is available here. A detailed wiki on producing slab rebar drawings in Revit using a RAM Concept model is available here.

Compatibility with Revit 2018

This version of ISM Revit Plugin is now compatible with Revit 2018, with continued support for Revit 2016, and 2017.

Load Case Mapping Enhancements

New features have been added the give the user more control over how ISM load cases are mapped to Revit load cases. The ISM Revit Plugin shared settings file now includes a mapping table for load cases. This gives you control over how load cases in ISM repositories are mapped to Revit load cases. This may be edited for any existing shared setting db files that have already been set up.

 

Error Corrections

No error corrections were included in this release of the ISM Revit Plugin.

Exporting Reinforcing from RAM Concept to Revit

Current Revision posted to RAM | STAAD Wiki by Wentao Zhang on 10/2/2018 1:16:18 AM

This wiki is intended to provide a quick start for transferring RAM Concept models into Revit for reinforcing documentation. In particular this wiki focuses on producing slab rebar drawings in Revit as shown in the image below.

Reinforcing that is transferred from RAM Concept into Revit can be updated without needing to recreate all reinforcing again, as opposed to RAM Concept's export dwg feature in which the entire drawing is recreated each time. This allows annotations that have been created in Revit to remain in place for all reinforcing that has not changed. A further advantage of the approach documented here is that a revision history of the project is stored in the ISM file and past revisions can be reviewed at any time.

Required Products

The exchange of reinforcing from RAM Concept into Revit is enabled by ISM Revit Plugin 10.2. We recommend the following versions of the required products:

Slab Design in RAM Concept

The workflow described here starts with a RAM Concept model and proceeds with the creation of a Revit model from the RAM Concept results. Note that it is also possible to start with a Revit model and create a RAM Concept model.

Open a RAM Concept model and run the Run Calc All process. Go to the reinforcement plan. Select all the reinforcing objects and set the Designed By field to User (as opposed to Program). This step is necessary because RAM Concept includes only reinforcement set to User in the ISM workflow.


After doing this all reinforcement in the model should be colored orange.


Note: Only one type of reinforcing object (Concentrated, Area, Transverse, etc.) can be edited simultaneously in RAM Concept. To narrow the selection to one type of reinforcing after selecting all reinforcing, right click and select "Selection Filter".

Save the RAM Concept model. Go to File -> Sync ISM -> Create Repository.

Assign a name and elevation to the floor and then proceed with the export to ISM.


Note: When creating a new ISM repository from RAM Concept (as opposed to updating an existing ISM repository), it is usually easiest to leave “Open Structural Synchronizer” unchecked as there is rarely any need to review the model in ISM. However, if the model contains a large number of objects that are not needed in the workflow (such as loads), significant time can be saved by opening Structural Synchronizer and rejecting these specific objects so that they are not transferred to the repository.

Once the export is complete, verify that the ISM model (*.ism.dgn) exists in the folder to which it was written.

Import of Model into Revit

Launch Revit Structure and select the template to use in the startup dialog.

Go to the Bentley tab in the Revit Structure main menu and select New from Repository.

Note: If the Bentley tab is not visible in the Revit main menu, verify that both Structural Synchronizer and the ISM Revit Plugin have been installed.

 
Set the path to the ISM repository that was created in the previous step. Uncheck the option Open Structural Synchronizer as there is no need to view the model in Structural Synchronizer prior to reading into Revit for the first time. Note though that when updating an existing Revit model with changes, it is recommended to use this option as the user can then reject any revisions he/she does not wish to bring into Revit.

 Select Next to advance to the Load Case mappings. Select Match All so that the program maps the ISM loadings automatically to Revit loadings.

Repeat the same process for the Material and Sections mapping dialogs. Click Next and allow the import process to complete.

Select Finish in the dialog above. Open the 3D view in Revit.

In order to see the reinforcing in Revit, select the 3D Wireframe view:



Now that we have 3D reinforcement in Revit, our next step is to produce 2D views from this information.

Set up Views in Revit for Documentation

Note that upon completion of the import process, plan views of each story were created automatically. This is located under the Structural Plans group in Revit's Project Browser. We will set up the plan view as the basis for a slab rebar drawing. Create a copy of the structural plan view using Duplicate View command.

All imported structural reinforcing path objects from Ram Concept have its comments filled with one of the below text:

  • Ram Concept Bottom Latitude Bars
  • Ram Concept Bottom Longitude Bars
  • Ram Concept Top Latitude Bars
  • Ram Concept Top Longitude Bars

We will add view filters to better organize our views (Note that this is a one time process, once view filters have been added, save Project as Template to avoid repeating this step in the future).

Add 4 filters on Structural Path Reinforcement's comment property containing Top/Bottom AND Latitude/Longitude.

The filters are now created. We now add them in the Visibility/Graphics dialogue.

Better organize your reinforcement plans by selectively toggling visibility of the Structural Reinforcement Path Objects. For example, separate plans by Bar Face and Bar direction:"Floor1_Bottom_Latitude Reinforcement" etc.

In order to see reinforcing in the plan view, set the transparency of the Floor elements to 60% using the Visibility/Graphic Overrides dialog.

At this point the rebar should be visible in the plan view. This includes both the Path Reinforcement and Area Reinforcement objects (the outline of the rebar region) and the Structural Rebar objects (individual bars). These objects can be toggled on or off and their display settings can be adjusted to produce the best results for reinforcing drawings and details. Rebar callouts as of yet have not been placed. This will be the next step.

Annotate the Reinforcing

To place rebar annotations and callouts on the plan view we will make use of the Tag command in Revit. We will use one type of tag for the rebar symbol and another type of tag for the text callout of the bar. These callouts can be adjusted and customized once they are placed.

Select the Tag All command under the Annotate menu.


Highlight the two items relating to Structural Path Reinforcement:


This will place annotations for all Path Reinforcement in the floor, including the rebar symbol and callouts as shown in the image below.

Now that annotations have been placed, we will turn off the display of the Path Reinforcement and Structural Rebar objects in Revit, leaving only the annotations. This is done by using the Visibility/Graphics Overrides and toggling of these objects as shown in the image below.

We now wish to adjust the placement of the annotations. This is done by simply dragging the annotations with the cursor.

Customize the Revit Families for Annotation

At this point the view is very close to the final presentation, but the callout text does not contain the information we wish to display. We will customize the callout by editing the Revit family. Select the text callout in the plan view and right click. Select Edit Family in the popup menu.

In the ensuing Revit window, select the label and then select Edit in the Properties pane. 

In the Edit Label dialog, customize the callout as desired by adding or removing properties from the Label parameters list.

Select OK. In the Revit Modify ribbon, select Load into Project and Close. When prompted to save the Family, select Yes and save choose a new name for the family. The drawing will now be updated for the new callout text. The plan view now reflects the desired final state we desire for our rebar annotations. The new Revit family can now be used for subsequent tags and projects.

Error Corrections

ISM Rebar import from Ram Concept– Previously, in certain circumstances US bar sizes were transferred into Revit incorrectly and defaulted to bar size #1. The correct bar size is now assigned (766177).

Concentrated Surface Rebars – Concentrated Surface rebars with rebar count of one were updated to rebar count of 2. Solution involves filtering for these type of ISM objects on import, as Revit’s Path Reinforcement object require a minimum of 2 bars (818408).

Import Crashing Revit - Certain rare invalid arrangement of loads and surface elements would cause import to crash (722006, 721355).

Studs imported from Ram Structural System – Studs imported from Ram Structural System would have its stud count shown separated with semicolons rather than commas (563440).

Current Revision posted to RAM | STAAD Wiki by Wentao Zhang on 10/2/2018 1:26:24 AM

NOTE: It is strongly recommended that users update to the most recent version of ISM, available HERE.

Reinforcement

ISM can now transfer, coordinate and visualize steel reinforcement in concrete structures. All of the typical reinforcement in columns, beams, footings, slabs, mats/rafts and walls can be modeled in ISM.

Reinforcement can use standard detailing parameters (for example, per ACI 318 or AS 3600) or can have custom bends and hooks defined. Bars can be epoxy coated, galvanized or plain. Post-tensioning is not included in this release.

Steel Joists

ISM can now transfer, coordinate and visualize steel joists. All of the Steel Joist Institute (SJI) standard joists (“8K1”, etc.) are supported, as well as SJI joist-girders and parametric steel joists.

Steel Deck and Composite Deck

ISM can now transfer, coordinate and visualize steel deck. Steel deck can be defined by manufacturers name (“ASC”/“2W-36”), defined parametrically, or even given custom shapes. Steel deck with concrete fill can also be modeled.

The following manufacturers are currently supported:

  • ASC Profiles (formerly ASC Pacific and BHP Steel Building Products)
  • Verco Manufacturing Company

More  Sections and Cold-Formed Sections

ISM can now transfer, coordinate and visualize steel deck. Steel deck can be defined by manufacturers name (“ASC”/“2W-36”), defined parametrically, or even given custom shapes. Steel deck with concrete fill can also be modeled.

ISM’s section library has been vastly expanded. The following standards are now supported:

  • ABNTNBR - Associação Brasileira de Normas Técnicas
  •  AISC- American Institute of Steel Construction (US and metric versions)
  •  API - American Petroleum Institute
  • AS - Standards Australia
  • AS/NZS - Standards Australia and Standards New Zealand
  •  BIS - Bureau of Indian Standards
  •  BSI -British Standards Institution
  • CEN - European Committee for Standardization
  • CISC - Canadian Institute of Steel Construction
  • DIN - Deutsches Institut für Normung
  • GB - Chinese National Standards ("Guobiao") ()
  •  IMCA - Instituto Mexicano de la Construcción en Acero
  • JIS - Japanese Industrial Standards (日本工業規格)
  • SAISC - South African Institute of Steel Construction
In addition, explicit support has been added for cold-formed C, lipped-C, tube, Z and lipped-Z sections. For tower construction, Schifflerized sections and bent-plate sections are supported.

Shear Studs

ISM can now transfer and coordinate shear studs on steel beams.

Nodes and Boundary Conditions

New analytical information has been added to ISM 2.0. Nodes and boundary conditions can now be transferred, coordinated and visualized. It is not intended that ISM track all of the nodes in an application’s analysis model. Applications only set the “key nodes” in ISM. “Key nodes” are those that define the intent of how members are connected, but do not include nodes that are only used to subdivide a member into more refined elements.

Nodes in ISM can have boundary conditions applied. Boundary conditions can restrain six degrees of freedom, and can be fixed, spring or one-way (compression-only or tension-only).

 

Curved Beams

 Beams and slab edges can now be curved. Only circular curves are supported, and slabs must still be planar.

Grid Systems

 Orthogonal and Radial Grid Systems are now supported.

Current Revision posted to RAM | STAAD Wiki by Wentao Zhang on 10/2/2018 1:26:24 AM

Release Date: December 13, 2017

Release Name: Structural Synchronizer CONNECT Edition Update 2

Release Version: 10.02.00.140

 

Download Instructions

Structural Synchronizer can be downloaded at the link here, or from Bentley Cloud Services. After signing into the CONNECTION Center, select Software Downloads under My Support. Once on the Software Fulfillment page, the installer can be located by performing a search on “Structural Synchronizer”.

Special Release Notices

Structural Synchronizer CONNECT Edition Update 2 installs both the Structural Synchronizer application and the Integrated Structural Modeling (ISM) framework. As with Structural Synchronizer 10.01.00.32, this release of Structural Synchronizer creates ISM 6.0 format repositories. There will be no upgrade required to ISM repositories published with Structural Synchronizer 10.01 after installing Structural Synchronizer 10.02. Repositories created with earlier versions of Structural Synchronizer will be upgraded to the ISM 6.0 when making changes to the repository contents.

New Features

This release of Structural Synchronizer includes the enhancements described below.

Single Unified Interface for ISM

Structural Synchronizer CONNECT Edition Update 2 is now a single unified application that contains the ISM Viewer, Revision Manager, IFC Import, and portions of ISM Editor all in one interface. Each of these capabilities used to exist as standalone applications that needed to be launched separately. These no longer exist in this version of the product and Structural Synchronizer is the single application name that will show as installed and that is referenced in product documentation. A video overview of the new interface is available below.

www.youtube.com/watch

Modernization of User Interface

This release features a new ribbon-based command menu which makes working with Structural Synchronizer significantly easier. Structural Synchronizer also now has Open File and Close File commands so that different files can be reviewed in the same session without having to close and reopen Structural Synchronizer.

Greater Control over Revisions

Past versions of Structural Synchronizer did not provide the user any control over what showed as revised when updating an ISM repository with changes made in an analysis application, or vice-versa. As a result, the user would often be returned a long list of revisions to sort through, many of which were small or inconsequential. This version of Structural Synchronizer allows any object property to be completely ignored, or considered only if the difference from the previous revision exceeds a specified numerical tolerance, when updating files in ISM workflows. Further, a specific configuration of these settings may be saved and reopened for use at a later time.

Mobile Publishing

Structural Synchronizer now allows ISM repositories to be published to the ProjectWise Projects space on Bentley Cloud Services. This allows any other product that reads iModels from ProjectWise Projects to open the file directly for review and coordination. This includes Bentley Navigator and Bentley Navigator Mobile, with which issue resolution workflows can be used.

CONNECT Integration

To support mobile publishing workflows, Structural Synchronizer is now integrated with Bentley Cloud Services. Users will now see commands for signing on to Bentley Cloud Services, associating the ISM repository with a CONNECT Project, and publishing the ISM repository to ProjectWise Projects, which allows the model to be viewed by any other team member with rights to the project. Using Structural Synchronizer in conjunction with Bentley Cloud Services requires the user to sign on to CONNECTION Client, which is installed with and launches with Structural Synchronizer.

CONNECT Advisor

This release of Structural Synchronizer includes CONNECT Advisor. CONNECT Advisor is a desktop application for interacting with different types of technical content on Bentley software, thereby eliminating the need to search various sources individually. Users can search for articles, whitepapers, videos, Bentley Learn courses, release notes, and more all in one location. CONNECT Advisor is configured to launch when Structural Synchronizer starts by default. This can be changed with the User Settings in the main CONNECT Advisor application window.

Notification of New Releases

Notifications will now be delivered when a new version of Structural Synchronizer is available for download. These notifications are delivered through CONNECTION Client. By default, CONNECTION Client is launched when Structural Synchronizer is opened. Simply sign in to CONNECTION Client to ensure you receive notifications of new Structural Synchronizer and other product releases.

File Format Compatibility

As with Structural Synchronizer 10.01, this release of Structural Synchronizer creates ISM 6.0 format repositories. There will be no upgrade required to ISM repositories published with Structural Synchronizer 10.01 after installing Structural Synchronizer 10.02. Repositories created with earlier versions of Structural Synchronizer will be upgraded to the ISM 6.0 when making changes to the repository contents.

Application Programming Interface (API) Compatibility

This version of Structural Synchronizer supports the new ISM API version 7.0 as well as earlier versions of the API back to version 3.0.

ISM API version 3.0 was not supported in the previous version of Structural Synchronizer. Support was added in this release to allow older versions of ISM-enabled applications that did not work with the previous release of Structural Synchronizer to be forward compatible with this release.

New Installation Experience

A new on-demand installer technology is incorporated into this version which reduces the initial installer download size to approximately 2 MB. The installer automatically downloads the required files during the installation process. The installer also supports creating deployment images for software deployment across multiple workstations.

Curved surfaces are common in Revit® and other applications. Functionality for curved walls or surfaces following arc or elliptical paths –including rectangular openings– has been added to the ISM 4.0 API, Structural Synchronizer V8i (SELECTseries 5) and ISM Revit plugin V8i (SELECTseries 5).


Curved members following elliptical paths have also been added (members could only follow circular arc paths previously). 

 

Substructures

Some applications need to synchronize with a portion of a large ISM repository or to synchronize multiple model files within a single repository. Substructures have been added to the ISM 4.0 API to provide a hierarchy and filtering tools so that applications can synchronize with a portion of a model without altering the rest of the repository.

Substructures are supported in the ISM Revit plugin by utilizing the current Revit selection set.

 

Substructures will also be supported in the next versions of ProStructures and AECOsim Building Designer. Applications which do not explicitly support substructures synchronize with the entire repository.

IFC Import and Expanded Export

IFC models are widely exported from applications not yet ISM enabled. Structural Synchronizer can now import Structural IFC models that can then by synchronized with other linked applications. 

The IFC import action can be started from the Windows Start menu - All Programs - Bentley Engineering - Structural Synchronizer V8i - Import IFC

 

ProjectWise Integration

Many ProjectWise users need the ability to synchronize ISM repositories that are saved to ProjectWise locations. Methods have been added in the ISM API to expose ProjectWise directories for all linked applications to use. Users with ProjectWise Explorer installed will automatically have the option to read and write files to secure locations or to cancel and save files normally to the local hard drive or network. This includes actions to Create Repository, Update Repository, Update from Repository, Export IFC, and Publish i-Model to name a few. Users without ProjectWise Explorer are unaffected by the change.

New Platform

Structural Synchronizer V8i (SELECTseries 5) is now built on Design Sync with a reduced installer, which also allows ISM synchronization technology to be used more broadly. Furthermore, the new interface makes some controls like level filtering and measuring easier to use and.

Compatibility Warnings

ISM 4.0 should not be used in conjunction with

  • SACS V8i SELECT series 3 (v05.06.01.07)
  • AECOsim Building Designer V8i (08.11.09.593)
  • STAAD(X) V8i (08.02.02.75)

Future releases of these products will be compatible.

NOTE: It is strongly recommended that users update to the most recent version of ISM, available HERE.

Version and Download Information

Release Date: January 24, 2017

Versions:

Download Instructions:

Structural Synchronizer can be downloaded from Bentley’s i-ware site here.

Structural Synchronizer can also be downloaded from Bentley Cloud Services. After signing into the CONNECTION Center, select Software Downloads under My Support. Once on the Software Fulfillment page, the Structural Synchronizer installer can be located by performing a search on “Structural Synchronizer”. 

Special Notices:

Installing Structural Synchronizer installs both the Structural Synchronizer application itself, used in interoperability workflows, and the ISM framework, used for programming. Once Structural Synchronizer is installed, the ISM options within all ISM-enabled applications will be available for use, as shown below.

This version of Structural Synchronizer publishes i-models to a newer format, DgnDb 0601, that cannot be read by Structural Navigator CONNECT Edition. Users must update to Structural Navigator CONNECT Edition Update 1 to open i-models published with this version of Structural Synchronizer.

RAM Elements CONNECT Edition (version 14.00) is compatible with ISM 6.0. RAM Elements V8i (version 13.XX) are compatible only with ISM 5.0 or earlier.

ProStructures users who utilize ISM should avoid upgrading to ISM 6.0, as Power ProStructures is compatible only with ISM 5.0 or earlier. Users with ProStructures for AutoCAD should avoid upgrading to ISM 5.0 or 6.0 as ProStructures for AutoCAD is compatible only with ISM 4.0 or earlier. 

New Features

The following enhancements were added in ISM 6.0 and Structural Synchronizer CONNECT Edition Update 1.

Piping Systems

This release incorporates piping systems into the ISM framework. Piping, bends, flanges, valves, pipe supports, pipelines, and piping reactions can now be written to and read from an ISM model with the ISM 6.0 API. Likewise, Structural Synchronizer now supports visualization and revision management for piping. The ability to now combine piping systems with structural elements in one ISM repository provides a robust framework for plant design workflows.

The ISM SDK documentation has been updated with piping interfaces new in 6.0. Coding samples are also now available that demonstrate how to build a structure using the ISM API. For more information on the ISM SDK, please contact Josh Taylor at Josh.Taylor@bentley.com.

New Sample Models

New sample repositories are delivered with the installation of Structural Synchronizer. These sample repositories are located in the following folder:

\Documents\ISM\Samples

The repository AutoPIPE Tutorial 1.ism.dgn was published from AutoPIPE using the tech preview interoperability with ISM. Basic Flat Slab (US).ism.dgn was published from RAM Concept. The repositories Building - Steel Over Concrete (Euro).ism.dgn and Concrete Moment Frame (ACI-318).ism.dgn were published from RAM Structural System. The beam, column, and wall reinforcing were designed in RAM Concrete.

Error Corrections

This release of ISM contains the following error corrections.

Transparency for Surface Member Modifiers Not Set Correctly

ISM published Surface Member Modifiers in such a way such that smart transparency did not work once the ISM repository was published to i-model and opened in Structural Navigator. As a result, regions of a slab that used Surface Member Modifiers, such as drop panels or thickened slabs, were not able to be viewed transparently in Structural Navigator and any reinforcing within these regions of the slab was not visible.

IFC Export Log File

When saving the log file in an ISM repository conversion to IFC using Structural Synchronizer, the user was given no control over where to store the log file. The last log file was simply overwritten.

What's New in STAAD.Pro CONNECT Edition Update 3, Build 21.03.00.146 ( 26 September 2018)

Issues addressed in:-

  • (A) Analysis/Design Engine (66)
  • (B) Generic GUI Updates (23)
  • (C) Analytical Modelling Workflow (39)
  • (D) Physical Modelling Workflow (25)
  • (E) Other Modelling Workflows (01)
  • (F) Analysis Post Processing Workflow (17)
  • (G) Other Post Processing Design Workflows (13)
  • (H) Interoperability (05)
  • (I) The Editor, Viewer and Other Modules (01)
  • (J) OpenSTAAD (03)
  • (K) Documentation and Printing (12)
  • (L) Licensing / Security / Installation (11)

(A) Analysis/Design Engine (66)

Sec Documentation A) 01 The AISC ASD design of wide flanged beams specified with a tapered web has been updated to improve the calculation of the allowable shear stress when using a STIFF parameter setting the distance between the stiffeners as the full member length. Previously this could be underestimated making this a conservative member design.

A) 02 The Direct Analysis method has been improved by removing the Notional Load setting from the definition as this was purely used to indicate that there should be iterations on determining the Tau-b value on members. Thus a single optional setting has been added to the PERFORM DIRECT ANALYSIS command, TBITER, which provides that as a single setting for the model.

A) 03 The analysis of models with releases specified on both analytical members and physical members was not handled correctly if the file defined the releases on the physical members after the analytical releases as the latter would over-right the former. This is not a problem if only analytical or only physical releases were defined in the model. This issue has been addressed.

A) 04 Pushover analysis is a feature available only with a STAAD.Pro Advanced license. If an analysis run is performed requesting Pushover analysis without using STAAD.Pro Advanced, a notification message clarifying this is displayed which has been made clearer.

A) 05 The design of HSS sections to AISC 360-05/10/16 have been updated to better support high strength tubes where the design thickness does not need to be reduced by 7%, which is required for tubes not constructed from A1085 steel. New tables of HSS sections have also been added.

A) 06 The design of steel sections to the Eurocode EN1993-1-1 with National Annex from Netherlands has been updated to ensure that when using the bi-axial bending check, equation 11.3-31, the reduced moment capacity about the Y axis was being assigned an incorrectly using the Mz capacity.

A) 07 Design of concrete beams to IS 456 have been modified to account for the maximum allowable spacing for non standard values of FY. Previously the required spacing was set to 25mm for any value of FY other than 250, 415 or 500 N/mm2

A) 08 The steel design to EN 1993-1-1 has been updated to better handle when the group of members being designed includes multiple RHS profiles that have slender classifications. Previously the second and subsequent profiles may not have used the correct effective section properties as required by the code.

A) 09 The Indian concrete design routines have been updated to now include support for the IS 13920-2016 code. This includes allowing for the detailing requirements of clause 6.1.4.

A) 10 The routines for specifying both equivalent static and response spectrum to the Indian code IS 1893 have been updated to include the option for following defining loads according to the 2016 version of the code.

A) 11 The steel design routines for the AIJ 2002 and 2005 codes have been re-architected to allow the designs to support the use of ENVELOPES, including strength, serviceability and temporary. This has resulted in a new and more comprehensive output reports.

A) 12 The routine to design circular hollow sections to the European steel code EN1993-1-1 have been updated to ensure that standard profiles defined as CHS can be SELECTED in the same way as profiles defined as PIPE.

A) 13 The output of designs to AIJ 2002 and 2005 include a unit reference of MM which should have read as CM. However with the re-architecture of these codes as listed in A) 11 above, the output has been completely re-formated to address this issue.

A) 14 The IS800:2007 steel design routine for checking wide flange profiles that had both top and bottom cover plates of differing dimensions has been corrected to ensure that the properties were calculated using the dimensions of the flanges as appropriate. Previously, the dimension of the top flange would be used for both top and bottom flanges.

A) 15 The Eurocode steel design routine, EN 1993-1-1, has been updated to ensure that if an angle profile is specified in a star arrangement (i.e. SA), then it is excluded from the design routines at this time as it is currently not a supported arrangement.

A) 16 The routines for specifying both equivalent static and response spectrum to the US IBC -ASCE 07)have been updated to include the option for following defining loads according to the 2015 version of the IBC code.

A) 17 The AISC 360-10 design routine has been updated to improve the determination of web slenderness of wide flange sections. It was using the overall depth of the section where as it should be using the less onerous depth between fillets.

A) 18 The cold formed steel design code AISI has been updated to address an issue introduced in the initial STAAD.Pro CONENCT Edition intended to extend the range of sections supported by the code. Laterally unsupported members should have the effective section properties determined by clause 6.4.3.1, but instead, the effective properties used the provided yield strength Fy.

A) 19 AISC 360-16 steel design has been updated to support torsion design of wide flange sections with cover plates to Design Guide 9.

A) 20 The AISC 360-10 design for wide flange beams with cover plates has been extended to include clause F4-2 (i) and (ii) Pg. 16.1-51. This check was previously missing.

A) 21 The ACI 318-14 concrete design routines have been updated to now support generating the output in metric units.

A) 22 Indian steel design routine IS801 has been withdrawn form this version of STAAD.Pro.

A) 23 The AISC 360-16 design routine has been updated to support the metric units KG, DMS, KMS, MTON, as previously these would have generated non-sensible output.

A) 24 The output of a design to AISC 360-16 using MEMBER SELECT, although correctly reported in the output file, was not being reported in the GUI or member query. These now report the final design from the SELECT operation.

A) 25 The output of a design to NZ 3404-1997 using MEMBER SELECT, although correctly reported in the output file, was not being reported in the GUI or member query. These now report the final design from the SELECT operation.

A) 26 The AISC 360 design routines have been updated to ensure that designs of wide flange sections defined with tapered webs do not impact the design of subsequent non-tapered sections.

A) 27 The Buckling Analysis in Advanced Analysis solution has been updated to handle the situation where a member is specified with restraints at both ends that prevent overall buckling irrespective of loading. Note that if there is concern of potential bucking between restraint points, then there should be one or more node points to allow for the anticipated buckling mode.

A) 28 The AISC 360-16 output report has been updated to ensure the slenderness limit is appropriate to the sign of the axial load of the governing case. This did not affect the design itself, just the output reported.

A) 29 The AISC 360-10 design output has been updated to ensure that the value of the effective length factor KZ and KY is the value used in the design. Previously, when the value of slenderness was not directly calculated as KL/R, but instead determined from clauses such as E5 for angles, an equivalent value of K was reported.

A) 30 The analysis engine has been modified to reduce license calls to improve the performance of the analysis start process.

A) 31 The Canadian steel designs to S16 2009 and 2014 have been updated to better handle models that have been specified with the SET Z UP option. To ensure that the correct member bending capacities are used.

A) 32 The AISC 360-16 steel design routines implemented for use with MEMBER SELECT have been updated to support members that fail due to slenderness do not end up as the final profile.

A) 33 The GUI has been updated to ensure that if a temperature load defined with a STRAINRATE is saved, the parameter is not changed to a STRAIN option.

A) 34 The analysis engine has been updated to support long material names which was previously limited to 36 characters.

A) 35 The Steady State analysis routine available in STAAD.Pro Advanced has been updated to address an issue with the AMPLITUDE method in the harmonic force loading using the parameters A, B and C (rather than rather than defining the frequency amplitude pairs). This method internally creates frequency-amplitude pairs, but did not provide sufficient space to use them correctly and could result in the application crashing.

A) 36 "The design of pipe and tube sections to AISC 360-05/10 have been updated to account for a required lower thickness value to be used for design of pipes/tubes. This reduction was included in the defined properties of US HSS sections, however, not so in tubular sections from other sources. Hence the following profiles are now being considered for the design thickness reduction as per sec.B4.2 with the parameter WTYP 0:- Pipe or tubes from any country database or UPT. Double channel face-to-face welded or pretension bolts (SNU 0) and zero spacing.

A) 37 The Direct Analysis routines have been enhanced to add additional information into the output file if during the analysis any of the the P-Delta iterations start to to diverge. This warns that the applied loading is exceeding the buckling load and whilst results may be obtained, this divergence may indicate that the results may be inaccurate.

A) 38 The processing of the option SET WARP provided to allow wide flange section members end warping restraints to be considered in the calculation of torsional stiffness rigidity, has been updated to address an issue which occurs where models are disjointed (i.e. two or more separate structures defined in the same model), the torsional rigidity would not be correctly calculated.

A) 39 The Mexican LRFD steel design module has been updated for the design of angle profiles to ensure that the method of MEMBER SELECT correctly addresses the section slenderness requirements which was causing the design to fail to select a suitable profile.

A) 40 The Indian cold formed steel design module has been withdrawn from this version of STAAD.Pro.

A) 41 The AISC 360-16 steel design routine for designing wide flange sections with cover plates has been updated to ensure that members with cover plates on just one side would not check the opposite flange as also having a cover plate, but of a tiny dimension. Previously this would have resulted in the flange without a cover plate being classed as slender.

A) 42 Currently the ACI 318-14 does not support design of plate elements. However, the previous releases would perform a design, but following the requirements of ACI 318-11. Now a warning is reported clarifying that this design option is currently not supported.

A) 43 The analysis engine has been modified to handle large models with dynamic analysis that generate large numbers of modes which previously exceeded the capacity of STAAD.Pro and resulted in a failure of the analysis.

A) 44 The IS800:2007 steel design modules for both LSD and WSD have been updated to allow the specification of LOAD ENVELOPE command to include envelopes of both Strength and Serviceability types.

A) 45 The IS456 Indian concrete design module has been updated to include two new parameters to define the cover to the main reinforcement, CLT for the clear cover to the stirrup over the top reinforcement and CLB for the clear cover to the stirrup below the bottom reinforcement. Additionally the default value of CLEAR has been modified to 30mm for beams, but remains as 40mm for columns.

A) 46 When designing steel wide flange shaped members to any code with any cover plates, the centre of gravity was not being calculated correctly (inaccurate by up to 2.5%)

A) 47 The analysis engine has been updated to handle models which have the Russian dynamic wind loading and a load case with a response spectrum load which previously would cause the analysis to fail.

A) 48 The IS456 Indian concrete design module has been updated to improve the determination of the section neutral axis for a given bar arrangement using a Newton Raphson algorithim which in some situations was previously failing to converge and failing the member design.

A) 49 A model which contains standard rolled hollow sections followed by UPT hollow sections, would fail to calculate the torsional constant 'C' for the UPT hollow sections. This situation has been addressed and the value of 'C' is calculated for all hollow sections.

A) 50 The AIJ steel design modules have been updated to include a test on the limit of b/t as specified in chapter 8.

A) 51 The AIJ steel design modules have been updated to determine the shear area of Tee sections to be, z-z axis = (2/3)* Bf * Tf, and y-y axis S.A =(2/3)* D * Tw.

A) 52 The AIJ steel design modules have been updated such that the shear area of circular hollow sections is now taken to be 0.5 * gross section area.

A) 53 The AIJ steel design modules have been updated such that wide flange sections with unequal flanges, will use a value of warping constant, 'Cw', as calculated from the formula published in Roark's Formulas for Stress and Strains, 6th edition, table 21, section 7.

A) 54 The AIJ steel design modules have been updated such that the parameter MAIN, which determines the compression slenderness check requirements, has been modified so that the value provided will determine the compression slenderness limit (similar to the TMAIN parameter). The default value of 200 will be used if not specified.

A) 55 The AIJ steel design module has been updated to report that wide flange sections that have additional cover plates are not currently supported.

A) 56 The AIJ steel design modules have been updated for design of double angle sections back-back where the major axis is parallel to the back to back legs (i.e. Y axis), then the allowable stress is determined to be 'ft', then allowable tensile stress. Where the major axis is perpendicular to the back-back legs (Z axis), then the allowable stress is determined from equations 5.7 and 5.8.

A) 57 The AIJ 2002 steel design module has been updated ensure that when calculating the allowable bending stresses for Tee sections or double angles, the direction of bending is checked such that if the flange is in compression a larger allowable bending stress is calculated, but if the web is in compression, a lower limit is calculated.

A) 58 The AIJ steel design modules have been modified such that the default check for VON MISES is now included unless turned off with the MISES parameter.

A) 59 The AIJ steel design module has been updated to ensure that when determining the bending stresses of unsymmetrical sections such as tee and and channel members, the appropriate section modulus is used for the direction of bending.

A) 60 The processing of a file that contains two analysis instructions separated with a CHANGE command but no change to the model or new load data has been updated and ensures that the results are retained. Note however, that if a load case includes an eigen solution, no recalculation of the eigen solution will be performed.

A) 61 The analysis has been updated to handle a situation that may arise in very large finite element models where the required memory for reporting the element stresses exceeds the available and should terminate the analysis. Previously, the analysis would continue and result in the analysis crashing.

A) 62 The output for concrete design to ACI 318-14 has been updated to better confirm the units being used. Units are defined by the first two characters, thus specifying the force unit 'KI' defines KIPS, even if the entered text for the force unit is 'KILONEWTON' or 'KILOGRAM'. However, the full entered text would be displayed in the output. Now the unit used by the program will be displayed.

A) 63 The analysis routine has been updated to ensure that using the KG option with a P-Delta analysis would not result in the analysis to crash due to attempting to access a temporary file created during the analysis process.

A) 64 The AISC 360-16 steel design routine for designing wide flange sections subject to 'minor axis bending only' has been updated to prevent the web (and thus the whole section) as slender. The code itself does not define this, but it is in keeping with the spirit of the section classification.

A) 65 The response spectrum processing routine has been updated for all methods (other than SNiP 2012 and SP14.13330) to ensure that it better handles modes that occur at exactly, or are extremely close to, the values of T0 or Ts, i.e. the limits of the flat section of the response spectrum curve.

A) 66 The analysis of models with solid entities that include a time history load and user defined Poisson ratio has been addressed to prevent this combination of characteristics causing the analysis to crash.

(B) Generic GUI Updates (23)

B) 01 The GUI has been updated to ensure that if any colour settings are changed, then those will be re-used in the subsequent sessions.

B) 02 The routines that link the help buttons in the GUI to the corresponding topic in the help documentation has been updated to provide a more comprehensive service.

B) 03 The Search tool provided in the upper right corner of the application has been updated to provide better responses and links to items in the ribbon bar and backstage.

B) 04 The method used to assign a model to CONNECT project has been updated to provide an indication that a model is not to be associated with a CONNECT project and not display the association dialog in future.

B) 05 A thin outline has been added to the various modules of the program to provide a clearer view of each when multiple modules are open and overlap.

B) 06 The CONNECT Advisor that provides a unified interface to interact with appropriate content to help with daily STAAD.Pro tasks has been re-configured to provide easier access.

B) 07 The actions of the Zoom Window icon and Dynamic Zoom icon in the View Ribbon have been swapped to be consistent with the actions from STAAD.Pro V8i.

B) 08 Clicking the mouse roller wheel and dragging is a quick action to allow the contents of a structure view to be panned. However, this action was not operational when the window was created as a Dynamic Zoom. The action has been added to Dynamic Zoom windows.

B) 09 The GUI has been updated to handle results produced by versions of STAAD.Pro V8i SS5 and earlier which used a different results database format which was not handled in later versions of STAAD.pro.

B) 10 The option to re-select the previous object selection has been added to the Select ribbon Cursors group.

B) 11 The Start Screen has been updated to provide convenient links to the sample and verification models delivered with the installation.

B) 12 The routine used to delete items selected in tables has been updated to ensure that the list of items was based on the index of the selected object rather than the table row number.

B) 13 The routine for importing Stardyne models has been removed from the program.

B) 14 The GUI has been updated to ensure that IX (torsional modulus) values of channel profiles are displayed correctly when the base unit is set to metric. Note that this only affected the displayed values and did not affect the analysis or design.

B) 15 The GUI has been updated to ensure that dialogs do not appear on the backstage when resizing the application window.

B) 16 The GUI has been updated to catch models which have been defined with multi-linear spring supports that have more than the maximum 100 displacement/stiffness pairs. Previously this would have caused the application to crash when opening the model.

B) 17 The tool-tip in the Configuration>File Format> Joint Coordinate Significant Figures has been updated to correctly list the valid range.

B) 18 The internal handling of memory while using the zoom functions has been updated to address situations which occasionally caused the application to crash.

B) 19 An additional check has been introduced when working with an archived file *.STZ, such that this model closed first before attempting to open a new archive file. Previously, such an action would result in the application crashing.

B) 20 The STAAD archive file format *.STZ has been registered with ProjectWise and this now allows an archive file to be opened directly into STAAD.Pro by using the Open routine or double clicking in a ProjectWise browser.

B) 21 The GUI file processing routine has been updated to ensure that if a UNIT specification is included prior to a DIRECT ANALYSIS specification this is retained when the file is re-saved.

B) 22 The GUI file reading routine has been updated so that it only processes the first 2 characters for any length or force specification and the details of this clarified in the documentation section TR.3 Unit Specification.

B) 23 The routine that allows quick access to items in a table by right-clicking and selecting 'Go to …' has been updated to ensure that this uses the selected reference rather than the table row number.

(C) Analytical Modelling Workflow (39)

C) 01 The Automatic Load Combination Generator has been updated to allow the specification of a starting number of the generated combinations and better naming of the generated combinations to clarify the conditions being met.

C) 02 GUI processing of Time History definitions specified using a spectrum option has been updated to ensure that when the data is written into the STD file, if it is required to extend over multiple lines, the use of the line continuation character results in a correctly formated file.

C) 03 The GUI handling of group definitions has been improved to ensure that if a member is split, then all resulting parts are retained in the group definition.

C) 04 The properties of HSS sections in the AISC database have been updated to use the full section thickness. Previously this was listed as the thickness reduced by 7% as required for the design.

C) 05 The processing of LOADLIST commands by the GUI has been updated so that it no longer splits any definition into multiple parts which might result in a reduced set of load cases for subsequent actions.

C) 06 The processing of external user provided tables (UPT) has been been updated to better handle cases where the external table does not exist.

C) 07 The legacy SURFACE objects are now fully removed from STAAD.Pro. In order to create a panel of finite elements which are properly managed by STAAD.Pro, the PARAMETRIC OBJECT should be used. It is further managed better still if created as a physical model in the Physical Model workflow.

C) 08 The GUI has been updated to allow the application of hydrostatic loading to members in a reference load case.

C) 09 The GUI display of wind loading has been updated to ensure that the values match those when exposure factors have been specified.

C) 10 The GUI routine that addresses the editing of a response spectrum load definition has been updated to better handle the condition where Individual Modal Response has been set, to ensure that this setting can be edited.

C) 11 The US AISC steel database has been updated such that the table of wide flange sections now shows the plastic modulus for the major axis as Zz. Previously this was shown as Zx.

C) 12 The routine for displaying the graph of wind pressure at a given height when using the ASCE7 option in the wind loading definition has been improved to provide better indication of the values resulting from this method.

C) 13 The GUI is now able to define node loads inclined from the global axes, previously this could only be specified in the Editor.

C) 14 The GUI routine that saves the details of a response spectrum has been improved to ensure that the details of the response spectrum does not exceed the limit of 79 characters on a line, but if necessary use the line continuation character to extend onto additional lines.

C) 15 The GUI has been updated to ensure that if the configuration option to save the member information in a single line format, then the format is used in the STD file.

C) 16 The ribbon control provided for selecting standard profiles from the collection of available databases in the Specification Ribbon, has been updated to be consistent with the control provided in the Section Database Manager tool.

C) 17 The Automatic Load Combination Generator has been updated to refer to IS456/800 and reflect the combination requirements in these codes rather than IS875-1:2002.

C) 18 The Automatic Load Combination Generation tool has been updated to ensure that it displays rules delivered by the program and created by the user.

C) 19 The macro provided by the installation to define combinations to the European Code in the Utilities>User Tools ribbon, has been updated to meet the requirements of the Win Basic VBA engine provided with STAAD.Pro CE.

C) 20 The Japanese steel section profile database has been update to include the current published profile properties , the addition o the profile H900x300x16x28, 74 new CHS profiles and 38 previously available T profiles have been removed.

C) 21 The GUI has been updated to ensure that if a wind load definition has been included in a load case, but not all the of the members have been specified with section profiles, the application will manage that. Previously, this could cause the application to crash.

C) 22 The GUI has been updated to support the addition of Custom Profile database in the Section Database Manager tool.

C) 23 The GUI has been updated to ensure that if a temperature load defined with a STRAINRATE is saved, the parameter is not changed to a STRAIN option.

C) 24 A new section profile database of tubes manufactured by APL Apollo has been added to the list of standard sections.

C) 25 The GUI has been updated to better handle the options of the PLATE MAT command and ensure that the correct settings are written into the STD file. The options XONLY, YONLY, ZONLY could be written incorrectly.

C) 26 The Load selection dialog available in the Loading and Results ribbon, has been updated such that in addition to selecting a load case as before, now by clicking on the up and down keys, it is possible to step through the other load cases and change the displayed loading/results without having to re-open the dialog.

C) 27 The User Table GUI has been updated to provide clearer feedback as to the actions taking place.

C) 28 The method used to display plate thicknesses in the Properties dialog box has been updated toe ensure that if the thickness is modified or material changed, the changes are reflected in the Property dialog immediately.

(D) Physical Modelling Workflow (25)

D) 01 The Physical Modelling workflow has been updated to now support static loading definitions, load cases and combinations (not just load groups). The load cases and load items also now sync with an ISM repository. Note that this means management of load cases is now controlled by the Physical Modelling workflow and not the Analytical Modelling workflow for physical models.

D) 02 The Physical Modelling workflow has been updated to better handle section profiles defined from the AISC 9th Edition catalog.

D) 03 Details of members designed using the MEMBER SELECT with design codes AISC 360-16 and NZ 3404-1997 are now reported back to the Physical Modelling Workflow and can be used to update the Physical Model.

D) 04 The processing of point loads on surfaces has been improved to allow loads to be applied to the very edge of the surface which previously would report as being outside the surface.

D) 05 The layout of spreadsheets has been simplified by providing the control in a context sensitive ribbon bar.

D) 06 The processing of the option to create the analytical model when only displaying a partial model view (i.e. only with some objects selected), has been updated to ensure that the entire model is created, not just the selected view.

D) 07 The spreadsheet tool has been updated to improve the experience of selecting items in the table by clicking on the first of the row, i.e. the index column and dragging up or down allows those additional rows also to get selected.

D) 08 The spreadsheet tool has been updated to allow members to be defined with un-registered nodes, i.e. such as only defining the start node, but if the spreadsheet is changed by say moving to a different sheet such as the nodes sheet, then only members with valid start and end nodes will be retained.

D) 09 The progress wheel displayed when generating an analysis model has been updated to better reflect the overall progress of the model generation.

D) 10 The spreadsheet tool has been updated to allow the data to be sorted by any column by clicking on an arrow on the column header. Clicking once will sort from low to high and second time from low to high.

D) 11 Members in the Physical Modelling workflow can now be tagged with Connection Tags which can be assigned to the start or end of selected members. These tags can be checked for the forces in the Analytical Model workflow according to the rules in the Connection Tag XML file. Any assigned tag will be transferred to the ISM repository when the model is synced and can be used to instruct detailers, using applications such as ProStructures, as to the connection to use in drawing production.

D) 12 The Member Segment function has been improved to ensure that members are divided into equal segments if the option is selected.

D) 13 The output panel has been enhanced with a filtering option to toggle the display of Error messages, Warnings or Notes.

D) 14 The backstage layout of the ISM interop and dialog have been revised to help retain coordination between the various ISM methods and retain a link to any repository used with the current model.

D) 15 The surface object supported in the physical model has been enhanced with support of a new circular opening definition. This definition is used to define openings on the analytical model and also included in the ISM interop.

D) 16 A new warning message will be displayed if the definition of an opening fails to successfully create an opening on a surface. Errors that are trapped include the boundary of the opening crossing the boundary of the surface and the boundary of one opening crossing the boundary of any other opening.

D) 17 The meshing algorithm used to create the analytical finite elements of surfaces has been improved taking into account the tolerance settings and adjacent/connecting surfaces.

D) 18 The import of models from an ISM repository has been improved on systems where the regional settings have been set to use a comma as the decimal separator.

D) 19 The spreadsheet table for grids has been updated to allow the addition of comments similar to that provided in other tables.

D) 20 The ribbon icon for labeling selected objects with their associated reference number has been updated to clarify its nature as a toggle which turns on/off the labels identified in the associated drop list.

D) 21 Generating the analytical model has been improved with a method to ensure that if an analysis model has been previously been generated, but some data is missing, then this data will be regenerated. Previously, the missing data would cause the analysis model creation routine to fail.

D) 22 The decomposition of the physical model to analytical data has been updated to improve the method used to update members that have been sub-divided into multiple parts using the 'Segment Model' after an initial analysis model has been created. Previously, some of the newly created analytical parts would be missing their profile and material specification.

D) 23 The method used to import an ISM into the Physical Model has been updated to additionally support members of type Polyline provided that they only have 2 defining points, start and end. Polyline members which have additional intermediate points are currently not supported.

D) 24 The create and update routines from the Physical Model to ISM have been updated to ensure that the alignment options match in both environments.

D) 25 The meshing routines have been improved to handle models which were failing to create analysis models due to small tolerances.

Current Revision posted to RAM | STAAD Wiki by Wentao Zhang on 10/3/2018 1:47:36 AM

Release Date: Coming Soon

Version: ISM Revit Plugin CONNECT Edition

Version Number: 10.03.00.08

 
Download Instructions

The ISM Revit Plugin can be downloaded from the Bentley store here. For Bentley SELECT subscribers, the ISM Revit Plugin can be downloaded from Bentley Cloud Services here. After signing in to the CONNECTION Center, select Software Downloads under My Support. Once on the Software Fulfillment page, ISM Revit Plugin installers can be located by performing a search on "ISM Revit".

 

Special Notices

The installation of ISM Revit Plugin CONNECT Edition will automatically uninstall any previous versions that were installed. This version of ISM Revit Plugin can be run in Revit 2017, 2018, and 2019.

ISM Revit Plugin requires ISM and Structural Synchronizer (both of which are installed with Structural Synchronizer). More information on ISM and Structural Synchronizer can be found here.
 

New Features

The following enhancements were added to ISM Revit Plugin 10.3.

Support for Revit 2019

Support for Autodesk® Revit version 2019 has been added. This release is compatible with Revit 2017, 2018, and 2019, and is no longer compatible with Revit 2016. This release requires Structural Synchronizer CONNECT Edition Update 1 or a later version.

Export of Isolated Foundations

The ISM-Revit Plugin now allows the import of Isolated Foundation (Rectangular Surface Members with only 1 column support) to be imported as the Revit Family- Isolated Foundation as opposed to previously imported Foundation Slab. This enhancement allows easier production of foundation schedules in Revit. The imported rebars are Structural Rebar Objects and can be tagged for drawing production purpose.

 

Error Corrections

Revit floor/deck span direction not exported to ISM, all decks have R-axis = 1,0,0– Evident in models containing slab with one way floor type other than 0 degrees. (907723).

Repository path field does not reflect the changes done by means other than file picker– Found in Operation Settings page of ISM file input field. (923278).

 

About ISM Revit Plugin

The ISM Revit Plugin enables a round trip exchange between Revit® and Bentley’s Integrated Structural Modeling (ISM) format, therefore also enabling a round trip exchange between Revit and any other ISM-enabled application. RAM Structural System, RAM Concept, and STAAD.Pro are examples of applications that are ISM-enabled and can interoperate with Revit with the help of the ISM Revit Plugin.

The ISM Revit Plugin adds commands to Revit that allow ISM repositories to be created and updated from Revit, and allow Revit to create and update ISM repositories. The ISM Revit Plugin is dependent on ISM and thus Structural Synchronizer must be installed on the computer.

Current Revision posted to RAM | STAAD Wiki by Allen Adams on 10/5/2018 12:25:22 AM

RAM Structural System CONNECT Edition Update 11 Release 15.11 Release Notes

Released Date: September 4, 2018

This document contains important information regarding changes to the RAM Structural System. It is important that all users are aware of these changes. Please distribute these Release Notes and make them available to all users of the RAM Structural System.

Occasionally last-minute changes or corrections are not included in these release notes. Updated release notes can be found at:

     https://communities.bentley.com and search for “v15.11”.

RAM Structural System CONNECT Edition Update 10 Release 15.10.

In order to avoid confusion between “Release 15.01” and “Release 15.10”, both internally in the program and externally with users, there is no version Release 15.10.

Bentley CONNECT:

Bentley is in the process of requiring all users to sign-in in order to use any Bentley programs. This is being done now in anticipation of the implementation of powerful and customized features intended to better help users perform their jobs. Moving to this sign-in requirement now better facilitates our implementing those new features.

If you do not already have a Bentley ID, go to http://www.bentley.com/profile and select the Sign Up Now link.

Bentley CONNECT already offers several benefits, and the value continues to increase. Listed here are three key features:

CONNECT Advisor

CONNECT Advisor provides links to pertinent articles, short training videos, courses and webinars. It can be accessed by selecting the Bentley Cloud Services – CONNECT Advisor command in the RAM Manager, or by selecting the CONNECT Advisor icon from the tool bar in any of the modules.

CONNECTION Center

When you sign in to your Bentley account you now have easy access to CONNECTION Center. This personalized portal gives you access to Usage reports, site configuration information, downloads, and Learning information on webinars, seminars and events, and includes a transcript listing the Bentley courses that you have completed. Your personal portal also lists your recent projects with a portal into analytics on that project. CONNECTION Center can be accessed by selecting the Bentley Cloud Services – CONNECTION Center command or by selecting the Sign In command in the upper right corner of the RAM Manager screen.

CONNECTED Projects

All of Bentley’s CONNECT Edition programs, including RAM Structural System, allow models to be associated with a project. Multiple models, from any of the Bentley products, can be associated with a given project. This simplifies the process of keeping track of work done for a project, and will enable analytics to be performed and reported for the project.

A ProjectWise Projects portal enables you and your project teams to see project details required to evaluate team activity and understand project performance.

  • View project activity by site, application and user
  • Gain insights into the users who are working on your projects and their effort
  • Register and manage your CONNECTED Projects
  • Access ProjectWise Connection Services including ProjectWise Project Sharing, ProjectWise Project Performance Dashboards and ProjectWise Issue Resolution Administration

When a model is Saved in this version the program will ask for a Project to which the file is to be associated. Projects can be registered (created) from your Personal Portal, or from the Assign Project dialog by selecting the + Register Project command.

Tutorial:

Except for minor corrections, the Tutorial Manual has not been updated but is still valid. The appearance of some parts of the program in this version may differ from that shown in the Tutorial.

Important Notices:

This version automatically converts databases created in previous versions to the new database format. Note that a backup file is created automatically when a database is converted; the name of the database is the same, with “Orig” and the version number appended to the name. The file has an extension of “.zip” and is located in the same directory as the original database.

The previous steel tables and load combination templates supplied with the program will be replaced with new tables and templates of the same name. If you have customized any Master or Design tables or load combination templates supplied with the program without changing the file names, those file names should be renamed from the original RAM table names prior to installation to prevent your changes from being lost.

Installation Instructions:

If you have enabled the CONNECTION Client you will automatically be notified of the newest version and will be able to update through that service by simply selecting the update command.

Otherwise, this version can be found on the Bentley Software Fulfilment web page by logging into the Personal Portal or the Enterprise Portal and selecting the Software Downloads icon. Perform a search for “RAM Structural System”, select any of the RAM Structural System modules (e.g., RAM Modeler; they all use the same installer), and select the latest version of the RAM Structural System.

Product Licensing FAQ:

Appendix A at the end of these Notes contains a document describing features available in the RAM Structural System to help prevent inadvertent use of unlicensed modules. Refer to that document for more information.

Security Risk Advisory:

Not applicable to this release. Every effort is made to ensure that there are no security risks in the software. There are no known security issues, no issues were addressed in this version.

New Features and Enhancements:

For details on these new features and enhancements, refer to the manual .pdf files available from the Help menu in each module or from the Manuals folder on your hard drive.

AISC Steel Tables

The design tables based on the steel shapes listed in the AISC Steel Construction Manual, 15th Edition, have been updated. This includes the Master, Beam, and Column tables for both the standard and the SI Equivalent shapes. Changes include new shapes and minor changes to a few geometric dimensions and section property values. Some minor corrections to ordering and grouping were also made. These new tables will replace the existing tables in the program Tables directory but will not automatically replace the tables in existing models; to replace those tables, if desired, use the Criteria – Master Table and Criteria – Design Steel Tables commands in the Manager.

Canada CAN/CSA S16-14 Update

In RAM Steel and RAM Frame Steel Design modules CAN/CSA S16-14 has been implemented as options for the design of steel members. For the member code checks performed by the program the differences between CAN/CSA S16-09 and CAN/CSA S16-14 are nominal.

Data Integrity

In rare cases, model data corruption so serious that the model could not be accessed or recovered was reported. When it occurred it was usually for very large models. The database is composed of many individual model and results files; the way the databases are saved during a Save command has been modified to better protect the essential model files even if there is corruption of the results files. This should result in a significant reduction in the number of cases of file corruption and loss.

SidePlate Connection Updates and Enhancements

Working closely with the engineers at SidePlate, the implementation of the SidePlate connections has been significantly updated and enhanced:

  1. New SidePlate connection types have been added. Previously the engineer had the choice of selecting either R = 8 or R = 3. Now the user selects from a list of connection types: Field Bolted SMF, IMF or OMF; Field Welded SMF; or Bolted Moment Frame (R=3).
  2. SidePlate has provided updated analysis and design parameters for the values provided with the program previously, resulting in more accurate and economical designs.
  3. Ability to model and check biaxial SidePlate connections for square HSS. Rectangular HSS will be implemented in the future. In addition to the biaxial interaction equation, the Strong Column – Weak Beam check is reported for both the Major and Minor axes.
  4. The Take-Off report has been updated to list the number of beam end connections as well as the total number of connections. Previously the quantities given for the plate material was approximate, the values are now more precise.

Data Check for Slab Edges

Two new Data Check items have been implemented to report potential problems with slab edges. When modeling slab edges they can be modeled associated with beams or walls, or free-form at any points around the perimeter of the structure. They can be offset from the reference line, or the slab edge can coincide with the reference line (no offset). This generally works very well, but in obscure cases slab edges with offsets in one-way decks that do not precisely align with the intended beam or wall can result in errors in loading. This condition may occur, for example, if a slab edge is laid down by snapping to a snap-point that is very close but not right on the intended beam, or if the framing is reconfigured and moved away from the slab edge. Although in the vast majority of cases these perform properly, the potential for unconservative loads warranted that Data Check items be added to find and warn of these conditions.

The program now checks each slab edge (and slab opening) – if it has an Offset – to see if its reference line aligns precisely with a beam or wall; if not it will give a message “Slab edge is not associated with a beam or wall”, with the coordinates of the slab edge.

Another condition that has been found to work incorrectly in a few obscure cases is a slab edge that spans multiple beams or walls. The program now checks each slab edge (and slab opening) – if it has an Offset – to verify that it starts and ends on the same beam or wall; if not it will give a message “Both ends of slab edge do not reference the same beam or wall”.

It may not be necessary to make any changes, the program may be handling the conditions correctly, but if corrections to the slab edge aren’t made you should verify that the loads on the beams in the vicinity of that slab edge are correct. Best practice when the deck is one-way deck and the slab edges and openings are defined with an Offset is to have the reference lines coincide with beams and walls, and to start and stop each segment on the same beam. Note that in the Modeler the Whole Perimeter command and the In Bay command will automatically correctly do this, and the Add command will automatically correctly break the slab edge into segments for each beam or wall if it is laid down correctly along a line of beams or walls.

Spread Footings with Large Overturning

The algorithms used to optimize spread footing dimensions have been refined, especially for the case of large overturning moments. Previously, some spread footings supporting frame columns were sized larger than necessary; these are now more economically designed.

Data Extractor – Technology Preview

The Data Extractor feature has been completely overhauled. This feature allows the user to extract model geometry, member properties, analysis results, and design information from the model. The extracted data can be saved to an Excel file, Access database, SQLite database, or XML file. It is called using the Post-Processing – Extract Data command in the RAM Manager. This feature is a Technology Preview feature, so it should be used cautiously. Rigorous testing has not been completed, and the feature – including the file formats – are subject to change based on user feedback. Please provide us with any feedback that you have from using the feature so that we can complete the feature to meet your needs. See Appendix B for details on using the Data Extractor.

 

Error Corrections:

Some program errors have been corrected for this version. Corrections made to graphics, reports, Modeler functions, program crashes, etc., that were considered minor are not listed here. The noteworthy error corrections are listed here in order to notify you that they have been corrected or to assist you in determining the impact of those errors on previous designs. These errors were generally obscure and uncommon, affecting only a very small percentage of models, or had no impact on the results. The errors, when they occurred, were generally quite obvious. However, if there is any question, it may be advisable to reanalyze previous models to determine the impact, if any. In each case the error only occurred for the precise conditions indicated. Those errors that may have resulted in un-conservative designs are shown with an asterisk. We apologize for any inconvenience this may cause.

RAM Manager

CONVERTED MODELS: Models older than v14.05 may have had their column data corrupted when converted to a newer version.

Effect: When it occurred, the model could not be opened.

RAM Steel Beam

ASSIGNED SIZED IGNORED: User-assigned beam sizes on stories other than the topmost occurrence of a typical floor layout were overridden by an optimized size during the Design All process.

Effect: When user sizes were assigned to the topmost occurrence of a typical floor layout type and a Design All command then performed, the user assigned size was respected. However, if the size assignment was made to a beam at any occurrence of that typical floor layout other than the topmost occurrence, the Design All process overrode the assigned beam size with the optimized beam size for all stories with that layout type.

CSA/CAN S16-09 HSS SHEAR CAPACITY*: The shear capacity for a Rectangular HSS was incorrect.

Effect: In calculating the shear capacity of a Rectangular HSS, the depth of the shear plane should have been reduced by 4 times the thickness of the web rather than 2 times the web thickness. A less conservative shear capacity was reported. For designs governed by shear, a member may have passed the shear check when it should have been failed.

CAN/CSA S16-09 CLASS 4 HSS: The flexural capacity calculated for Class 4 HSS sections designed according to CAN S16-09 was incorrect

Effect: The design and reported flexural capacity for Class 4 HSS was incorrect. The reported capacity was conservative. Designs which should have otherwise passed, may have been reported as failed.

RAM Steel Column

CSA/CAN S16-09 HSS SHEAR CAPACITY *: The shear capacity for a Rectangular HSS was incorrect.

Effect: In calculating the shear capacity of a Rectangular HSS, the depth of the shear plane should have been reduced by 4 times the thickness of the web rather than 2 times the web thickness. A less conservative shear capacity was reported. For designs governed by shear, a member may have passed the shear check when it should have been failed.

CAN S16-09 AXIAL CAPACITY: The reported axial capacity according to CAN S16-09 was incorrect when members were uniaxially loaded in flexure. The reported axial ratio may also have been incorrect.

Effect: While members were correctly designed according to CAN S16-09, the reported axial capacity and ratio may have been incorrect for members under uniaxial bending loads. The critical axial ratio may have been incorrectly reported. Crx or Cry may have been reported rather than Cr, the governing capacity. This was a report error only.

CAN/CSA S16-09 CLASS 4 HSS: The flexural capacity calculated for Class 4 HSS sections designed according to CAN S16-09 was incorrect

Effect: The design and reported flexural capacity for Class 4 HSS was incorrect. The reported capacity was conservative. Designs which should have otherwise passed, may have been reported as failed.

RAM Concrete Analysis

ASSIGN – COLUMNS – EFFECTIVE LENGTH: When trying to assign Column Effective Length (K factor), an unsupported operation message would be displayed.

Effect: Concrete Column K factor values could not assigned or changed.

RAM Concrete Column

ACI 318-14 SLENDER COLUMNS: When determining amplified moments per ACI 318-14 6.6.4.5.4 for slender columns, the program considered the minimum moment in each axis simultaneously. The code specifies that the minimum should be considered separately for each axis.

Effect: This was unduly conservative.

ACI 318-08 SMF JOINT CHECK: The SMF joint code check report referenced ACI 318-99 in the controlling code section rather than ACI 318-08.

Effect: When ACI 318-08 was the design code, the SMF joint check design was correct but the references given were from ACI 318-99.

RAM Concrete Shearwall

SHEAR CAPACITY*: When a horizontal bar layout was modified in View/Update, the shear capacity calculation was based on the original assigned bar pattern rather than the updated bar sizes.

Effect: Shear capacity was incorrect.

RAM Frame – Analysis

WALL RIGID LINKS AT BEAM-TO-WALL LOCATIONS*: If the option "Include Rigid Link at Fixed Beam-to-Wall Locations" is selected and if certain conditions are met, it enforces wall rigid links at locations of beams framing into wall. The program mistakenly applied the same condition even for walls sitting on beams. In this case, it enforces wall rigid links for walls sitting on beam.

Effect: Analysis results are not valid if the option is selected and if the model includes lateral walls sitting on lateral beams.

DIAPHRGAM FORCES FOR SLOPED SEMI-RIGID DIAPHRAGM: The program failed to calculate diaphragm forces if diaphragm was sloped.

Effect: The Diaphragm Forces report was not produced if diaphragm force calculation was called for a sloped diaphragm

IS1893-16 RESPONSE SPECTRA LOAD CASE: The program did not allow creation of IS 1893-16 Response Spectra load case.

Effect: The load case was in the list, but would not function; the load case was not available for analysis.

RAM Frame – Shear Wall Forces

WALL SECTION CUTS: Could not create section cuts that started and ended in an opening on a single wall.

Effect: Could not review forces between wall openings and wall edges.

RAM Frame – Steel Standard Provisions

AISC 360-16 DOUBLE ANGLE HORIZONTAL BRACES*: The program crashed when a code check of double angle horizontal braces was performed according to AISC 360-16.

Effect: While all other horizontal brace shapes could be designed according to AISC 360-16, double angle horizontal braces caused the program to crash. The error did not occur when designing per any of the other design codes.

CSA/CAN S16-09 HSS SHEAR CAPACITY *: The shear capacity for a Rectangular HSS was incorrect.

Effect: In calculating the shear capacity of a Rectangular HSS, the depth of the shear plane should have been reduced by 4 times the thickness of the web rather than 2 times the web thickness. A less conservative shear capacity was reported. For designs governed by shear, a member may have passed the shear check when it should have been failed.

CAN S16-09 AXIAL CAPACITY: The reported axial capacity according to CAN S16-09 was incorrect when members were uniaxially loaded in flexure. The reported axial ratio may also have been incorrect.

Effect: While members were correctly designed according to CAN S16-09, the reported axial capacity and ratio may have been incorrect for members under uniaxial bending loads. The critical axial ratio may have been incorrectly reported. Crx or Cry may have been reported rather than Cr, the governing capacity. This was a report error only.

CAN/CSA S16-09 CLASS 4 HSS: The flexural capacity calculated for Class 4 HSS sections designed according to CAN S16-09 was incorrect

Effect: The design and reported flexural capacity for Class 4 HSS was incorrect. The reported capacity was conservative. Designs which should have otherwise passed, may have been reported as failed.

RAM Frame – Steel Seismic Provisions

Emh FOR COLUMN DESIGN*: Column code checks performed according to AISC 341, Section D1.4a were incorrect when beam ends were not modeled exactly at supporting column coordinates or modeled outside the tolerance for detecting supported beams at columns.

Effect: In a rare condition where beam ends were modeled outside the tolerance for detecting members framing into the tops of columns (which could occur, for example, when the members aren’t modeled cleanly in some other program and then imported into the Modeler), code checks incorrectly calculated Emh because the framing beams were not found. The design and report axial loads for columns where the framing beam was not detected was incorrect. When lateral beams were modeled correctly at column supports, the error did not occur and code checks were correctly performed according to AISC 341.

AISC 358 IMF Cpr: When AISC 358 provisions with a specified value of Cpr not equal to 1.1 was specified for the "Other" checkbox selection, reports for Intermediate Moment Frames (IMF) did not correctly show the user specified Cpr value.

Effect: Although IMFs were correctly designed using the user specified Cpr value, the report incorrectly listed a Cpr of 1.1 when the AISC 358 provisions were selected and the specified Cpr was Other (Eg. WUF-W). The defect was a report error only.

RAM Foundation

OVERTURNING SAFETY FACTORS: In some cases the calculated values of the overturning safety factors were incorrect, based on previous iterations of size rather than the final size.

Effect: Report error and unnecessarily conservative design.

OVERTURNING SAFETY FACTOR: In the design criteria of the Foundation module there is an option to consider the moment due to shear (for all three footing types). When calculating the safety factor for overturning, the moment due to shear was considered even if this option was deselected. In addition, when computing this safety factor, the moment due to shear was double counted when the option was selected.

Effect: The overturning safety factor value was incorrect (conservative).

RAM Connection Link

CONVERTED MODELS: RAM Structural System models that had a RAM Connection link file (.rcsx extension) were not keeping that file when converting from version 15.08 to version 15.09.

Effect: File would no longer be in the 15.09 model, but it was still in the backup file created during convert. The file would need to be manually copied from the backup to the new 15.09 files to restore it.

Revision 1 posted to RAM | STAAD Wiki by Karl G on 10/5/2018 1:01:18 PM
 Applies To 
 Product(s):RAM Concept
 Version(s):06.05.00 and later
 Area: Licensing

The objective of this tutorial is to build on the skills learned in Chapter 45 of the RAM Concept Manual, a flat plate tutorial for ACI 318, and show how post-tension (PT) slab design and engineering workflows can be improved using the PT Optimization feature. During the tutorial, a base design found using traditional manual optimization techniques is compared to the best design found by the Optimizer. The tutorial also outlines key modeling best practices that are important for successful optimizations.

The Chapter 45 tutorial model, which is installed in the Tutorial folder of the root RAM Concept program files directory, is useful for learning how to model manual and generated tendons, layout design strips, and review the results. While the PT layout in this model produces a valid design with no code failures, it is not intended to represent the most economical design for the slab. For example, the slab thickness and PT quantities could be decreased without producing design failures or sacrificing performance (deflection, vibration, etc).

We have modified the original tutorial model to produce a more economical design. The modified file can be downloaded here (hyperlink will be added). Significant changes from the original tutorial model are summarized in the next section. The file has been prepared for optimization and is ready to be optimized without any modeling or criteria changes. This model represents the base design and used to judge the success of the Optimizer.

This tutorial focuses on modeling tips and design workflows only and is not intended to be a step-by-step guide on how to use the PT Optimization feature. Please see the RAM Concept PT Optimization Feature Article for an outline of the basic steps required to run optimizations in the program.

Model Notes

The significant changes from original tutorial model are listed below:

  1. The typical slab thickness was reduced to 8 inches.
  2. The balcony slab thickness was reduced to 6 inches.
  3. All drop caps were removed.
  4. Tendon quantities and profiles were selected using a traditional manual iteration process.
  5. All tendons are modeled on the tendon parameter layers since manual tendons are not optimized by the Optimizer.

The revised model is saved with a manual design that was completed by Jonathan Hirsch, PE, the Development Manager of RAM Concept. He has 23 years of post-tension design experience, is an active member of the Post-Tensioning Institute (PTI), and currently chairs the PTI Education Committee.

During the manual design process, tendons were initially modeled with minimum precompression, and tendon quantities were gradually increased until a valid design was obtained. The total engineering time to produce the optimized manual design was about 1 hour.

Examples of traditional manual design methods that were used to select the base design include:

  1. PT forces were increased until the top service stress near the supports at or near the code limit. The image below shows the allowable service tensile stress (blue diagram, 6*sqrt(f’c) per ACI 318-14 24.5.2.1) and the maximum service stress (red diagram) at one of the interior columns.
  2. PT forces were increased in some spans to reduce the bottom service stress in positive moment regions below 2*sqrt(f’c) and eliminate bottom reinforcement (see ACI 318-14 8.6.2.3).

When reviewing the base design in the revised tutorial model, you will see that bottom reinforcement remains in many of the spans. Increasing PT force to reduce bottom service stress and eliminate this reinforcement in these spans either resulted in stress failures or increased stud rail reinforcement in other areas. This illustrates another important point with manual designs: often there is not a well-defined stopping point and the most efficient change is not intuitive. Changing tendon quantities in one area to reduce reinforcement cost can create a design issue that requires an increase in PT or reinforcement in another span, and so on. The Optimizer allows you to easily compare hundreds of possible designs and automatically eliminates the designs that do not satisfy code requirements. This eliminates the need for tedious manual iteration and saves hours of engineering time on a typical project.

Tutorial Instructions

  1. Download the modified tutorial model (hyperlink).
  2. Create a copy of the downloaded file.
  3. Open the tutorial model and its copy in 2 separate RAM Concept windows. Note that opening 2 simultaneous sessions of the program on a single machine counts as only 1 license use.
  4. Review the model using Optimization Tutorial – Best Modeling Practices (hyperlink) as a guide.
  5. Run the designs in one of the open models. Review the generated tendon design and the resulting cost data in the Estimate Report.
  6. Run an optimization in the other open model. CONNECT sign-in and Bentley Cloud Services credits (ACUs) are required to run optimizations within the program. Please click here for more information on ACU credits. Click here for step-by-step instructions on how to run an optimization.
  7. Load the best trial into the model after the optimization is finished. See Step 8 in the step-by-step instructions.
  8. Review the results and cost data of the optimized design and compare to the base design in the original model using Optimization Tutorial - Results (hyperlink) as a guide.

Tutorial Results and Summary

Cost estimates before and after the optimization are summarized in the table below.

This tutorial demonstrates the following:

  • The Optimizer generates a more economical design when models are set up using best practices. For this model, the Optimizer found a design that was approximately 6% more economical than the design found by manual iteration.
  • The Optimizer saves significant engineering time. For this model, the optimizer would have saved more than 1 hour of engineering time spent by an expert engineer. Larger time savings are expected in larger or more complex models. The time spent finding an economical design manually could have been devoted to other engineering tasks.
  • The Optimizer investigates potential solutions that are not possible with manual designs due to time constraints. Manual designs tend to focus on reducing PT quantity only. Possible solutions that add PT but reduce other reinforcing costs are typically not considered due to time and budget constraints. The Optimizer does things like adjust tendon profiles to balance moments at joints and reduce punching shear demand, which would not be practical in a manual design. In this model, the best solution is one that increases PT cost but reduces reinforcement and stud rail costs, and in turn, the total model cost.
  • The Optimizer automatically controls deflection. Deflection is not explicitly considered by the optimizer. However, it tends to find solutions that produce reasonable deflections. In this model, the most economical design had more PT, which resulted in a lower service deflection than the manual design.
