RCDC-Column & Shear Wall

• Can RCDC handle columns of shape L, T and other odd shapes?
  • Yes. RCDC can design any shape of column like L, T, I, E, Capsule and polygons up to 12 edges. It also has an option to create user defined sections. For more information refer Topic “Irregular Shaped Column” for column from help Content.

• When equal number of bars are provided in all columns from plinth to top floors. After design it’s showing lesser bars at the bottom and more at top.
  • RCDC designs the column floor-wise. If percentage reinforcement required at a given level is more than the lower floor then it could be because of higher moment at that floor. Normally this happens at terrace floor where moments are more as compared to lower floors. This can be checked as per efficiency ratios in the design table.

• Some of the columns are missing at lower level even if they have exist in Staad model.
  • If the model has column members with no joints at in between levels, then these columns will appear ‘Missing’ in those levels. This can be checked by generating column elevation.

• Forces for column do not match with analysis.
  • RCDC reads the forces only for Primary load cases. These will match with the analysis forces. The forces for combinations are computed within RCDC as per load factors and other conditions like (LLR) Live load reduction. If the conditions of LLR are matched in analysis and RCDC, the design forces will match. For foundation design, RCDC uses member forces and not support reactions. In case of rotated columns or columns with offset, the support reactions do not match with member forces.

• In edit link arrangement all the internal links can be removed. It doesn’t affect the design of links in column design. Please clarify.
  • Option of Edit link arrangement is provided to change the link arrangement. It is provided only as detailing tool and not linked to design. User is expected to check the shear requirements before modifying it. Also it may be noted that, diameter and spacing of links is not recalculated after editing of links. For more information refer Topic “Edit Link Arrangement” for column from help Content.

• Does RCDC calculate the Effective length factor automatically or it is user defined? Is it same for all columns in model or different?
  • RCDC identifies the sway or Non-sway frames factor as per storey stiffness and storey index. It calculates relative stiffness of the beams and columns as per column orientation. It calculates the effective length factors as per available charts for Sway and Non-sway. Effective length factor would be different for all columns as per calculations. Option of overriding effective factor is available to user. User also can apply single factor to all columns on one click. For more information refer Topic “Effective Length Factor” for column from help Content.

• Does RCDC designs shear wall for out of plane moments in addition to in plane moments?
  • RCDC designs the sections as per the forces from analysis. In addition to the forces from analysis, RCDC calculates moments due to minimum eccentricity in both major and minor directions and performs section design. If applicable, slenderness moments are added in the final design moments. For cross-section design of walls same principles as column design are followed.

• Can we design shear wall/wall with single layer (mesh) of reinforcement?
  • No. Shear wall design with single mesh is not available as it is designed for the axial force and biaxial moments.

• RCDC uses the formula of column for the “Minimum Eccentricity Calculation” (in IS code), though it is different for shear walls as per Clause: 32.2.2 of IS 456-2000.
  • Clause 32.2 in IS 456-2000, is for Empirical Design Method of walls. Clause 32.3 is for design of walls subjected to horizontal and vertical loads and same has been followed in design of wall in RCDC.

• Please clarify the braced and un-braced design conditions.
  • These are design principles chosen by structural engineer for design of buildings. These are beyond purview of RCDC. RCDC captures this as information for further calculations.

• Lateral ties diameter, spacing & no. of columns main bars are correlated by formula given in IS: 13920 for rectangular and circular column. Can any single parameter be provided to calculate remaining two parameters in RCDC, once the initial design is complete?
  • Yes. After initial design is completed, user can change the numbers and diameter of main reinforcement in redesign option. Diameter and spacing of links can be changed. For any parameter changed in redesign process, RCDC would design/ check the column with all relevant clauses. For more information refer “Edit Local Column Design” from help Content.

• Pl refer to Annexure A off IS 13920 which states walls are to be designed for uniaxial bending. Columns are considered as biaxial. Hence, their design cannot be clubbed under one set.
  • Annex A of IS 13920 is about the calculation of moment of resistance of the web portion of rectangular wall section. This is further used only in calculation of effective axial force in boundary element due to major axis moment. It may please also be noted in IS 456 which is the main code for design there is no separate procedure for design of walls. Clause no 39.6 of IS 456 refers to members subjected combined axial and biaxial bending which includes column and walls. Thus for biaxial design RCDC follows the basic principle of plotting P-M curve for design and checks for boundary element using annex-A provided in IS 13920. For more information refer Topic “Technical discussion” for column from help Content.

• Can we have calculations for boundary zone length in wall design?
  • Boundary elements are provided for ductile walls as per IS 13920. Governing Criteria to provide Boundary element is if stress is more than 0.2*fck and Boundary wall terminates (along the height of wall) if stress is less than 0.15fck. Zoning of reinforcement is done around the boundary element. The initial length of the boundary element is arrived at as per procedure discussed in help. For more information refer Topic “Technical discussion” for column from help Content.

• RCDC follows ductile detailing as per 13920 for outer ring of boundary element but reduces link dia. & spacing for inner links.
  • As per ductile detailing, for the calculation of confining links (outer links in BE – BE main) of boundary zone, formulation of Ash as per IS 13920, clause 7.4.8 is used. The internal links (BE others) are provided at same spacing with lowest possible diameter to maintain the “h” value in calculation of Ash. At middle zone, the links are provided as per IS 456. As a standard practice RCDC provided links to all longitudinal reinforcement.

• Can RCDC design Curved beams? Will it convert the curved beam composed of many parts to a single physical beam?
  • Yes. If curved beam is modelled in sufficient small parts then RCDC identifies it as single beam as per the geometry and support conditions. The beam is designed for Bending, shear and torsion as per regular beam.

• Can RCDC provide bottom bar without curtailment in single span?
  • RCDC has the option of detailing bottom reinforcement as Best fit and Max dia. user can use option of Max diameter to maintain the same number of bars at bottom most layer. For Best fit it curtails the bars at support if it is allowed as per detailing requirements.

• Can number of bars for the given width of beam be edited?
  • Yes, User can set the number of bars as per width of section in "zone bar setting" option. It also checks the minimum and maximum spacing criteria at the same time. For more information refer Topic “Preferred Bar Spacing” for beam from help Content.

• Can RCDC provide the detailing of beam with lowest diameter throughout the length and balance area of steel with higher diameter in other layer?
  • Yes. It can handle this only for top reinforcement. To maintain the lowest bar at top user can select “min dia.” option in general setting. Lowest Bar diameter and numbers will be provided across the length of the beam and remainder will be provided at next layer of reinforcement. This option will result in detailing like 2-T12 at first layer and 2-T25 at second layer. For more information refer Topic “General and Reinforcement Settings” for beam from help Content.

• Does RCDC allow to provide only 2 bars for top reinforcement?
  • The Number of Bars suggested by RCDC are as per beam width and maximum spacing criteria given in codes. User can change the numbers of bars prior to design subjected to spacing criteria given in code. For zero bending moment zone RCDC can provide minimum two bars with minimum bar diameter. For more information refer Topic “Preferred Bar Spacing” for beam from help Content.

• What is the purpose of mirror & straight option in group/ungroup tab?
  • Mirror grouping option can be used if beams are mirror in arrangement with same geometrical properties. So beam on one side can be mirror in detailing of the beam on other side. Similarly if beams are identical in plan i.e. beam geometry is similar at a given level and repetitive then these beams can be grouped. For more information refer Topic “In Plan Grouping” for beam from help Content.

• Why specifically only 13 stations (for beams) can be imported from E-tabs to RCDC?
  • 13 stations divides the element in to twelve parts. As per standard practice of all codes, curtailments of reinforcement lies at L/4, L/6 and L/3 of span where L is the span of the element. Dividing the element in to 13 station satisfies all the requirements of curtailments. Curtailment of reinforcement helps in beam detailing thus it is mandatory to provide 13 stations to all beams in the analysis. Staad automatically provides the results at 13 stations. E-tabs can provide results at any stations as per user requirements Thus in E-tabs user has to assign output stations as 13 before exporting the results. For more information refer topic “Technical Discussion” of beam and Column from help Content.

• Side face reinforcement (SFR) is designed for beams even though the depth is less than 750mm, whether there are any options to enable/ disable side face reinforcement?
  • In RCDC, SFR is calculated as per design requirements including torsion. User can provide the SFR even it is not required in design. In many cases for beams with depth less than 750 mm, there may be torsion, which would result in SFR. User may check the detailed calculation report for clarification.

• Please give clarification of failure type for beam element. Failure type – Shear –Tc max
  • Tc max failure means Tv exceeds the maximum permissible shear stress.

• Even after opting best fit for top reinforcement, why does RCDC provides higher reinforcement (as per minimum Pt) at top at mid-span?
  • This would be typically doubly reinforced section which causes more reinforcement at top even when moment at that location is nominal. In the calculation report it can be clearly checked where Asc-required at mid-span is captured. This is the top reinforcement required at that section.

• Why default 0.2% is provided for nominal steel in RCDC? Does it have any reference?
  • RCDC provides the nominal steel where bending moment is ZERO. Default value provided in RCDC for nominal steel is 0.2 %. This is an approximate Value and we have kept the value close to minimum steel in beam. The above value is editable and can be put as per user requirements. For zone with no Bending Moment, RCDC uses nominal steel and for detailing, it would adopt 2 bars with minimum diameter possible.

• Is there any option to disregard the contribution of concrete in resisting shear for beam when IS: 13920 is used?
  • No. Beam shear design is as per IS 456. Shear induced due to Sway action is calculated as per IS 13920. For Sway shear also the part of shear is arrived from the dead and live load. Thus RCDC does not allow to ignore the concrete for shear design.

• When IS: 13920 is selected, does RCDC consider required rebar or provided rebar to calculate capacity (plastic) shear force (or moment capacity) for beam?
  • Yes. RCDC designs the beam shear as per Clause 6.3.3 of IS 13920 and consider the reinforcement provided to calculate the moment capacity. For more information refer Topic “Calculation of Ductile Shear” for beam from help Content.

• Does RCDC calculates moment capacity for sway shear calculations as per rectangular section or flanged section for beam?
  • For moment capacity of section RCDC always considered as a Rectangular section as Flange section is not applicable at support. Also to get the flange action, flange has to at compression side which is not the case at support. For more information refer Topic “Flanged Beam” for beam from help Content.

• Does RCDC design the irregular slab like L, T shapes and slab having more than four edges?
  • Yes. Rectangular and odd shaped slabs can be designed in RCDC. RCDC designs the two way and irregular slab based on yield line theory. For odd shaped slab RCDC considers the largest span as shorter direction for design. For Aspect ratio (L/B) RCDC considers the outer-most dimensions of the irregular slab. As per the aspect ratio of irregular slab it identifies whether the slab is one way or two way. For design using ACI, the two way and irregular slab are based on direct design method. For more information refer “Technical Discussion” of slab from help Content.

• For square/rectangular panels of slab, can RCDC transfer the load to two adjacent edges (beams) only as per user choice? 
  • No. RCDC designs the slab as per relevant clauses and based on explanation provided in relevant codes. RCDC automatically identifies continuity based on the edge conditions. User can change end conditions as per requirements. User can change the type of slab like one way or two way as per choice. RCDC will design the slab accordingly. For more information refer “Technical Discussion” of slab from help Content.

• RCDC is considering some slabs as cut-outs but actually we have modelled those slab instead of cut-outs in E-tabs.
  • In E-tabs, sometimes user models single membrane or shell for many number of slabs combined in one large entity. Thus in this case, individual slabs bounded by beams can’t be read by RCDC. For more information refer “Slab auto-detection” of slab from help Content.

• Tensile factor for deflection of slabs is limited to 2.0 in IS 456 but RCDC provides value 2.26 in the design calculations. Please clarify.
  • Calculation of tensile factor is based on the formulation available in SP24 clause 22.2.1. IS 456 has provided the graph up to value 2.0 but it is not restricted as far as formulation is concerned. Higher values can be considered in design to control the deflection.

• For which load combination, number of piles in the pile cap design are decided?
  • Number of piles are decided as per maximum load on one pile and group of piles for all service load combinations. Checks for maximum load on one pile and group of piles are added in design calculation report. Maximum Load on one pile and group of piles for each load combinations are added in the Pile Capacity Check & Sizing report. For more information refer “Technical discussion” of Pile-cap from help Content.

• Kindly clarify whether Development Length in Compression (Ld) is considered, while arriving the depth of Foundation or a Pile Cap.
  • For footing and pile-cap RCDC does not considered the “Ld” of the column reinforcement for minimum depth. Column design is an independent activity thus information of column reinforcement is not available for pile-cap design. User can provide minimum pile-cap depth available in general settings as per Ld requirement. Also if required each pile-cap can be redesigned with required minimum depth.

• Does 25% increment for group of pile is applicable in lateral load cases?
  • As per code 25% increment is applicable for one pile for lateral load. For individual pile in a group of piles, the check is performed for 125% of pile capacity. However for group of piles, the 25% increment can’t be applied. For more information refer “Technical discussion” of Pile-cap from help Content.

• How the effective self-weight of the footing is calculated?
  • Effective self-weight of footing is calculated as additional load of footing volume with respect to difference in density of concrete and soil. For more information refer “Technical discussion” of footing from help Content.

• For calculation of two way (punching) shear, footing self-weight is not added to axial load.
  • Concept of Footing punching shear criteria is column punches in the footing. Load from the column punches the column in footing. Self-weight of footing, overburden load do not participate in punching of column as it is a uniformly distributed load, thus it is not considered in design. For more information refer “Technical discussion” of footing from help Content.

• As per design, required reinforcement is 1478/1528 sqmm along L/B direction. Provided reinforcement is T12@175 mm which amounts to 1453 sqmm only for 2.25 m width of footing, whereas the calculation report shows Ast provided as 1583sqmm. Please clarify.
  • Width = 2250 mm Ast required = 1478 sqmm Reinforcement provided = T12@175 mm In RCDC the number of bars required are calculated and spacing is calculated. While presenting the spacing rounded to 5 mm. In this example, number of bars as per spacing would be calculated as below – (2250 / 175 = 12.86 which is 13 spaces). Hence number of bars would be 14. Thus actual Ast-provided would be (14x113.097 = 1584) 1584 sqmm which is more than required.

• Please clarify the footing type “on raft” given in RCDC.
  • RCDC designs the isolated footings. The purpose of this options is to maintain the same thickness of first step for all footings if all footing are connected by common raft. This type of footing mostly use in the basement structures. The concept of this type of footing is similar to stepped footing.

• How is the volume of trapezoidal footing calculated in RCDC?
  • RCDC calculates the weight of trapezoidal footing as per following formulations, Self-wt. of footing Volume of footing = ((L*B*D) + ((((L*B) + (Lt*Bt))/2)*(D-d))/1000^3 Where, L= Length of footing B= Width of footing D= Depth of footing Lt= Length of footing top Bt= Width of footing top d= depth of sloping area

New Features and Enhancements:

RAM SBeam V7.00.00 contains some powerful enhancements:

AISC 360-16

The requirements of AISC 360-16, “Specification for Structural Steel Buildings”, as found in the AISC Steel Construction Manual, 15^th Edition, have been implemented. This includes the new requirement for composite beam design to consider stud ductility.

CAN/CSA S16-14

The requirements of Canada CAN/CSA S16-14, “Design of Steel Structures”, have been implemented.

IS 800-07

The requirements of India IS 800-07 WSD and LSD have been implemented. The requirements of IS 800 are new to RAM SBeam.

Stud Criteria

The Stud Criteria have been enhanced. Minimum percent composite action can now be specified for long spans versus short spans. There is now an option to specify a maximum stud spacing of “Rib Spacing” when the deck is not parallel to the beam; this provides a means of specifying that studs be placed in every rib. There is an option to enforce the AISC 360-16 Commentary method of satisfying the new Stud Ductility requirements; for beams greater than 30 ft long this will result in either a minimum percent composite action of 50% or else a stud spacing of no more than 12” oc. Note that this is a new Specification requirement in AISC 360-16, but this option is recommended when designing to any AISC specification.

Error Corrections:

Some errors in previous versions have been corrected in v7.00. The more significant errors are listed here. The error only occurred for the precise conditions indicated. Errors that may have resulted in un-conservative designs are shown with an asterisk. We apologize for any inconvenience this may cause.

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.

MAX STUD SPACING WARNING: If the rib spacing is greater than the user-specified Maximum Stud Spacing (such as can occur when the deck is skewed), a message is correctly given that the Max Stud Spacing exceeds the Rib Spacing, but no warning was given to indicate that the maximum spacing wasn't satisfied (because of that). The additional warning is now given, that the stud spacing exceeds the Maximum Stud Spacing.

Effect: In that case the design was correct except that it did not satisfy the user-specified Maximum Stud Spacing. There was a stud in every rib, but the ribs were spaced too far apart to satisfy the criteria.

C-BEAM CAMBER: When C-Beams (formerly called SMARTBEAMS) are optimized, the design gives an acceptable range of Spacing or Diameter (for Cellular) and a range of Phi (for Castellated). This means that there is a corresponding range of member depths and section properties, and as a result, a range of deflection values. The program reported camber consistent with the worst strength interaction rather than the worst deflection encountered.

Effect: Report error only. The reported camber may have been inconsistent with the reported components of the worst deflection encountered. The reported camber was correct for the hole configuration associated with the worst strength interaction value, but was not necessarily correct for the hole configuration that caused the greatest deflection. The impact on camber was very small.

RAM Structural System CONNECT Edition Version 16.01 CL Release Notes

Release Date: April 18, 2019

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 “v16.01”.

CONNECT Licensing.

CONNECT Licensing was first implemented in the RAM Structural in v16.00. This licensing monitors current usage and, if an attempt is made to use a program or module for which there is no available license, the program will give a warning. Important information is given in the v16.00 Release Notes. More information on CONNECT Licensing can be found at:

https://communities.bentley.com/products/licensing/w/licensing__wiki/37813/connect-licensing

and a short guide has been posted here:

https://communities.bentley.com/products/ram-staad/m/structural_analysis_and_design_gallery/273502

CONNECT License requires all users to sign-in in order to use any Bentley programs. If you do not already have a Bentley ID, go to http://www.bentley.com/profile and select the Sign Up Now link.

NOTE: If you haven’t done so already, before using this version, the person at your company that has the role of Administrator for the Bentley products must configure the license so that it gives the overuse warnings. Otherwise, by default no warnings will be given. Instructions can be found here:

https://communities.bentley.com/products/licensing/w/licensing__wiki/38540/1---connect-licensing-for-administrators-getting-started

Review all of the information, but in particular, note the section on Entitlement Management, and in that document note the instructions on License Alerting. Generally, for License Alerting you will want to Enable Alerts, and then input the number of licenses that you own for the particular product.

CONNECT Licensing is revolutionary. It warns you against incidental overuse of the program, but when you have a temporary heavier work load it allows you to intentionally use more licenses than you own, at a fraction of the cost of purchasing an additional copy. CONNECT Licensing gives you the information you need to control usage and make those decisions.

Bentley CONNECT:

In addition to providing the overuse warning described above, Bentley CONNECT offers several benefits. 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.

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.

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:

The database used in this version is compatible with databases used in V16.00 and V16.00.01, so no conversion of those databases is necessary. For databases from earlier versions, this version automatically converts those databases 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.

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. Note that with CONNECT Licensing, warning messages are given in the event there is no license available, so it generally isn’t necessary now to block modules using that feature.

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.

Floor Vibration

For floor vibration analysis, the updated version of FloorVibe V3.0 is now installed with the program. It can be launched in RAM Steel Beam using the Vibration – AISC Design Guide #11 command. FloorVibe has been developed by Thomas Murray, a world-renown expert on floor vibration, through his company Structural Engineers, Inc. This version of FloorVibe includes the updated 2^nd Edition of the AISC Design Guide #11, Vibrations of Steel-Framed Structural Systems Due to Human Activity.

Story Data

The Story Data command in the Modeler has been enhanced to allow generation of story labels and story data for a single level or for multiple levels. To generate a story label, a Style (e.g., “First”, “1st”, “1”, or “One”) and the Enumerator of that style to be used in the label (or the first of a range of enumerators to be used when generating a range of Story data) are selected. A Prefix and/or a Suffix can also be specified (e.g., “Story”, “Level”, “Residential”, etc.). When the data is being generated for multiple stories the range of levels is specified, and then when the Add command is invoked the data for each story in the range is added to the table, with the label generated by incrementing the Enumerator for each level (e.g., “2nd”, “3rd”, “4th”, “5th”). The story data generated for a range will all be assigned the same Flr to Flr Height and Floor Type, but those can subsequently be edited. The file containing the Styles and Enumerators can be edited; for example, a Style could be added where the Enumerators are in a language other than English.

Splice Level is used to identify the levels at which column splices occur in gravity Steel columns. Yes means that a splice is allowed at the level (and hence the column size can change between this level and the level above), No means that a splice is not allowed at the level (and hence the column size is not allowed to change between this level and the level above). It is common to alternate the splice location at every other level (i.e., the column section spans two stories between splices). An “Alternate” option has also been added to the designation of the Splice Level. When this option is selected the Splice Level selection of Yes and No will automatically alternate as each story is added to the Story data table.

Reduced Beam Sections

In RAM Frame, the Reduced Beam Section Properties dialog has been enhanced to automatically provide a, b, and c dimensions for the RBS cuts, based on user-specified defaults. When a size is assigned to a beam that has been designated to have the RBS moment frame connection, the program automatically adds that size to the Properties list and assigns the cut values. The fractions for a, b, and c, as well as the increments to which the cut dimensions are to be rounded, can be set by the user in the Defaults Utility, and edited if desired in the Reduced Beam Section Properties dialog. The resulting tabular values can be edited to refine the design. If the resulting values are outside the acceptable range given in AISC 358, a warning will be given.

Pile Cap Design Reports

The Pile Cap Footing Design report has been enhanced to more clearly indicate the design warnings. The text of the warning messages has been improved to clarify the nature of the problem. The same changes were made to the warning messages in View/Update.

The Pile Footing Design Summary report has been enhanced to identify any pile caps that have any design failures. Previously that report only listed the design information but did not indicate any failures (the failures are listed on the individual Design reports).

The Spread Footing Design Summary report has been reformatted to identify any spread footings that have any design failures, in the same format as is used in the Pile Footing Design Summary and in summaries in other modules.

Steel Table Selection

The Beam Steel Table Selection dialog, invoked using the Layout - Beam - Steel Table command provides a means of assigning whether a steel beam is going to be designed using the Default Steel Table or the Alternate Steel Table. Previously the assignment of steel tables as Default and Alternate was only done in the RAM Manager. Now this can also be done directly from the Beam Steel Table Selection dialog in RAM Steel Beam. A similar enhancement was made for the selection of the Steel Joist Default and Alternate tables.

Wall Thickness Display

When the Options - Show Sizes command is invoked in the Modeler, the wall thickness of Concrete and Other walls is now displayed. Previously only beam sizes were displayed when that command was invoked.

Column Eccentricity

The Echo of Input Data report has been enhanced to list the beam connection eccentricity used to calculate the gravity moments in the column due to the beam reaction applied at the eccentricity from the centerline of the column to the connection. The value is reported either as the absolute distance from column centerline or as the distance from the face of the column, depending on how it was assigned by the user.

DirectX Diagnostic Tool

In the RAM Manager a command to launch the DirectX Diagnostic Tool has been added to the Help - Technical Support menu. This may be helpful when working with Technical Support to troubleshoot graphics problems.

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 Steel Beam

STUDS ON BEAMS WITH WEB OPENINGS*: If the design of a composite beam with a web opening is controlled by M-V interaction of the tee, it is possible in some cases to eliminate required stiffeners by adding additional studs. When that condition occurred the program attempted to add additional studs to determine if the stiffeners could be eliminated, but in some cases would determine that the stiffeners could be eliminated but did not specify the required number of additional studs.

Effect: For the case where the M-V interaction of the tee of the composite beam controlled the beam design the program may have indicated that no stiffener was required but may not have specified the proper number of studs to satisfy the web opening design without stiffeners. Error did not occur if anything else controlled the design of the beam.

RAM Concrete Shear Wall

SECTION CUTS: In some cases (random), the program didn’t allow a section cut to be made at the location specified by the user.

Effect: Section cut couldn’t be made at the desired location.

COUPLING BEAM DISPLAY: In some cases coupling beam assignments were not displayed.

Effect: Coupling beam assignments could not be displayed or edited. Generally in that case, the program would crash if View/Update was performed on that wall.

NOTE: Several corrections were made to the wall and coupling beam data and related commands that were causing the program to crash.

RAM Frame – Analysis

WALL POINT LOADS TAKEDOWN*: If a lateral column supported multiple levels of lateral walls above, gravity point loads on wall may have been lost, not transferred into the supporting columns.

Effect: Gravity loads in such columns were not correct. This defect was partially fixed in V16.0 but the error persisted in some configurations.

WALL GROUP FORCES: If a series of adjacent wall panels were modeled with one of the panels having an opening that extended across the entire panel width, the Wall Group Force values were incorrect.

Effect: Conservative values listed for the Wall Group Forces for the configuration given.

RAM Frame – Steel Standard Provisions

JOINT CODE CHECK: If a steel joist framed into a moment frame joint the program erroneously flagged the joint as invalid (that is, a joint with a configuration for which the program cannot perform a joint code check).

Effect: The joint code check was not performed on that joint.

TORSIONAL BUCKLING*: For AISC 360-05 and AISC 360-10 the program was not checking Torsional and Flexural Torsional Buckling requirements for I- shapes as required when the torsional unbraced length exceeded the lateral unbraced length.

Effect: Unconservative member design if Torsional or Flexural Torsional Buckling requirements should have controlled the design. In the program this very rare and could only occur if the user over-rode the program-calculated value by assigning a shorter value of Lu using the Assign – Unbraced Length command.

AISC 360-16 UNBRACED LENGTH*: In the calculation of the flexural capacity of beams the program used the axial unbraced length value, Luy, instead of the weak axis flexural unbraced value, Lby.

Effect: Potentially incorrect flexural capacity. No error occurred if the unbraced lengths were the same for both axial and flexural bracing, which is often the case. When the error did occur it was always conservative unless the user assigned an explicit value of axial unbraced length Luy that was shorter than Lby.

ASSIGN MEMBER UNBRACED LENGTH*: With the Assign – Unbraced Length command for columns, beams and braces, if the user selected the option to Use a specified unbraced length for Unbraced Length - Axial, and the option to use Global Criteria for Unbraced Length - Flexure, the Use value intended only for Unbraced Length - Axial was assigned to both Unbraced Length - Axial and Unbraced Length - Flexure.

Effect: An assigned unbraced length intended only for the Axial unbraced length may have been used in design for the Flexure unbraced length. The error did not occur if the program-calculated unbraced lengths were used.

RAM Frame – Steel Seismic Provisions

EBF COLUMN WIDTH-THICKNESS RATIO*: The Width-Thickness Ratio limit used for EBF Columns designed according to AISC 341-10 and AISC 341-16 was incorrect.

Effect: The width-thickness limit of 0.38 SQRT (E/Fy) rather than the more stringent limits set for Highly Ductile elements in Table D1.1 was used.

OCBF - EXPECTED BRACE FORCE*: The reported expected brace force for braces designed according to the AISC 341-10 and AISC 341-16 specification was incorrect per the requirements of Section F1.6a.

Effect: A post buckling brace force was reported as the expected brace force for the OCBF brace designed according to AISC 341-10/16 specification.

RAM Foundation

TRANSVERSE REINFORCEMENT: When the reinforcement optimization was turned off the program sometimes gave an erroneous message that the soil capacity check failed.

Effect: Incorrect error message given. Rare.

LATERAL RESISTANCE OF PILE CAP: The check of total lateral force with the total shear resistance of the piles was done using strength combinations instead of service combinations.

Effect: Design warning may have erroneously been given that the lateral resistance of the pile cap (based on pile shear capacity) was insufficient for the applied lateral forces.

INCORRECT MOMENT DIAGRAM: The View/Update in continuous footing showed an incorrect moment diagram for a single concrete load case.

Effect: Drawing error only.

Appendix A

Product Licensing FAQ – RAM Structural System

Licensing Restrictions Options

The RAM Structural System is composed of several modules, each of which has their own license. The program also contains links to two related Bentley products, RAM Concept and RAM Connection, providing design interoperability, as well as a link to Bentley’s ProjectWise for project management. Each of those programs also have their own licenses. It is possible to have several licenses of one or more modules, and few or no licenses of other modules. Because of the ease with which these various modules and programs can be invoked, a method of restricting the use of each has been incorporated in order to prevent unwanted or inadvertent usage by an unsuspecting user from being logged against the licenses that the company actually owns.

These modules are invoked using the tool bar buttons on the left of the RAM Manager screen:

or by using the Model or Design menu items:

If RAM Concept or RAM Connection are not installed, they will not be available to be selected.

There is no license associated with RAM Manager, so no usage data is logged against it, but usage data is logged against each of the other modules as soon as they are invoked.

There is no demo version available for the RAM Structural System modules.

VERSIONS 14.07 AND NEWER

In RAM Manager, the Tools – Manage License Restrictions command opens the following dialog:

This provides a mechanism for the user to prevent a module from being inadvertently executed. When the program is first installed all of these options are selected. It is important therefore to execute this command and deselect any modules or links for which the user wants to restrict access.

To prevent a module or program link from being executed, deselect that item.

If a module is deselected here and that module or link is subsequently invoked, the following dialog appears:

If Allow is selected the module will open, and usage will be logged. If Cancel is selected the module will not open and no usage will be logged. Settings opens the previous command, allowing the user to modify the selections of the allowed modules.

VERSIONS 14.06 AND EARLIER

Versions prior to V14.07 lacked the ability to manage these license restrictions, restrictions could only be achieved by deleting the module from the installation Prog directory. If you are using an earlier version and want to prevent use of a module, delete the file(s) listed here for the module to be prevented:
