Hello, Sorry for my typo. The version number is 22.6.00.138. It is STAAD.Pro Connect Edition update 6. I have edited in the above also.

Cheers!

Thank You Abhisek for the verification. I think the issue is resolved in the STAAD version you have used. I tried the same running in both SS6 and Connect edition update 4 (22.4.0.40) with compression in IS 800. even with TMAIN 400. Can you please let me know the title of the version you have? Is it connect edition update 6? I'm not able find it with the version number so that I can try running in that version. Thanks again

Hello,

I have tested your file with both the codes in latest version 22.06.00.138 and getting tension for both the case as shown below.

Here, for both the cases slenderness is the guiding. Now for members with tension, if you do not assign any TMAIN parameter value, the program will calculate as per default value set. Please refer the snaps to know the ratio calculation reported.

Thanks for the reference article. However, my question was not about slenderness failure. The issue is member with same 'Member Tension' specification takes up compression for design using IS 800 LSD against tension in AISC 360.

I have checked this file in both Connect edition & SS6. Both work the same way. I have attached the .std file for your reference.

Which STAAD.Pro version are you using? Can you attach that STAAD.Pro model?
