When multiple tapered members are designed in group with CHECK CODE ALL command vs. designed individually, the design results do not match. Noted for multiple codes like AISC /IS 800/ S16.

STAAD.Pro is not able to read the external user table files and is generating errors like

*** ERROR : FILE NOT FOUND C:\...\...

**ERROR- IN READING MEMBER PROPERTIES. CHECK DATA FORMAT CAREFULLY.

Provide the full path name to the file. For example instead of specifying

START USER TABLE

TABLE 1 wf1.txt

END

specify the input as shown next

START USER TABLE

TABLE 1 C:\Model_folder\Model_name\wf1.txt

END

STAAD.Pro is crashing during analysis when SELFWEIGHT is applied to a list as shown next

LOAD 1 LOADTYPE Dead 
SELFWEIGHT Y -1 LIST 1 TO 100  

There is an error in plotting of the axial force diagram (FX) for TRUSS members. Wedges are formed at the ends instead of a uniform plot. The values are correctly computed in the analysis.

For tapered member design as per AISC 360-05 code, design results are coming out different when members are designed in groups vs individually

Design the tapered members individually each with its own CHECK CODE command

When the report option Output > Steel Design Detail is used to get detailed design report, the generated report is incomplete for some codes like AISC 360-05 or AISC 360-10

One can get the detailed design report ( TRACK 2 output ) printed in the analysis output file. A concise version of design report can be obtained by including the option Output > Utilization Ratio Table

Some users were not able to access the STAAD News from within the startup page and also not able to connect to the Personal Portal using the Connection Client Widget.

For those users experiencing the problem the following workaround is suggested.

1. Close all Bentley products.

2. Uninstall the existing Connection Client ( from within Control Panel > Programs and Features )

3. Download an Updated Bentley Connection Client from the following page http://communities.bentley.com/products/structural/structural_analysis___design/m/structural_analysis_and_design_gallery/271606

4. Click on the Download button on the right to start downloading. Please note that you have to be logged in with your Bentley Login to be able to download the file.

5. A zip file BentleyCC.zip will be downloaded. Extract the contents of the zip to any folder in your machine and you will find 3 files

   blg6410000319en.exe

   blog10000319en.exe

   ConnectClientClrWrapper.dll

6. If you have a 64 bit OS, right click on the first exe and choose Run as Administrator to install the connection client.

7. Alternately if you have a 32 bit OS, right click on the second exe and choose Run as Administrator to install the connection client.

8. Copy the file ConnectClientClrWrapper.dll to the folder C:\SProV8i SS6\STAAD\ConnectClient. There will be a file by the same name in that folder. Replace it with this one.

9. Log in to Connection Client using your Bentley login credentials.

Design for Tee Sections as per AISC 360-10 for which critical condition  is  H2-1 may   not be correct as software is not considering the correct section modulus for all cases.

Note : This issue is Addressed in 20.07.11.70

Workaround if using older version

In a Pdelta analysis with tension/compression, the pdelta effect is not considered in section force calculations unless each load case is followed by the PDELTA ANALYSIS and CHANGE.

The design of double angles as per IS800:LSD code is incorrect. The cross sectional properties for Y and Z axes got reversed due to which the design is being done incorrectly.

Slenderness calculation and hence compression capacity caclulation for double angle sections as per IS800:2007 is incorrect.

If any primary load case containing self weight is included in a Repeat Load case, the effect of self weight on member section axial forces gets ignored, thereby producing incorrect axial forces at intermediate section locations for the Repeat Load case. The values at the start and end of the member are correct.

Deflection check as per AISC 360, IS 800, S16-14 codes are always reporting last load case in the serviceability envelope as critical load case for deflection. The design is correct and reports the correct critical ratio. It is just the reporting of the critical load case which is incorrect and that too when deflection governs. So for any design where deflection is not the governing criteria, this reporting error does not have any effect.

Double Channel Front to Front cannot be designed as per AISC Unified 360-05 and 360-10 codes. An ERROR: MEMBER DESIGN FAILED FOR MEMBER xx is reported 

The error in noted in version 20.07.11.70. The sections can be designed in earlier versions like 20.07.11.33, 20.07.10.65 etc. This will be addressed in SS6 SP3 release planned for Q2 of 2016.

Deflection check as per AISC 360-10 and AISC 360-05 is incorrect and reporting incorrect ratio and incorrect location of critical section.

Incorrect section properties considered for design of Pipe sections ( PIP ) when design is carried out as per IS800:2007 code and multiple members are part of the same design command ( like CHECK CODE ALL, SELECT ALL )

This error is detected in version 20.07.11.70 and will be addressed in the build of SS6 expected to be released in Q2 of 2016. The properties are considered correctly for design when the members are designed individually (like CHECK CODE MEMB xx ). So a temporary workaround is to have separate design commands for each individual member having a pipe cross section.

For IS 800 2007 design, STAAD.Pro does not do bending check for I sections with slender flanges. The members may be shown as PASSed based on axial and shear checks without bending being actually checked. This is not evident unless one asks for a TRACK 2 output and hence could be misleading. 

The only workaround for now is to ask for a TRACK 2 output where a related warning is displayed. The Bending capacity is reported as 0 in the Design tab within Member Query dialog box. This error is discovered in 20.07.11.70.

In some cases, when connections are designed using the RAM Connection module launched from within STAAD.Pro, the connection status is shown as Pass in the Design Report sheet, but shown as "No Good" in the table.

The error has been observed in version 20.07.11.70 and will be addressed in the SS6 SP3 release of STAAD.Pro expected to be released in Q2 of 2016.

When trying to add any design parameter as per EN 1993-1-1:2005 code, a warning message shows up saying 'Warning, Design code license is not activated. Please activate the license in order to use the code'. The software does not allow to add any design parameter or even check code command to be added for EN 1993-1-1:2005 code. The same issue has been observed for some other country codes as well like the ACI, CSA086-01 etc.

This error has been found in build 20.07.11.82. A simple workaround is presented below

While adding the first design parameter, one needs to check the box 'After Current' before clicking on the Add button. The design parameter can then be added. Subsequently all other design parameters and CHECK CODE command can be added as usual without any errors.
