Hello!
I have had a colleague come to me with a problem with the latest STAAD CE (v22.01.00.39). They created a simple truss model, and when checking the compression chord (Beam 3) on the outside of the truss, the loading diagram and beam end results are correct (compression), however for the code check for AISC 360-16 STAAD assigns the load as "tension".
(CONNECT v22, AISC 360-16)
(CONNECT v22, AISC 360-10)
This was checked back to STAAD SS6 v20.07.11.90 and compared to the previous version of CONNECT (v21), and the code check was showing the correct "compression" indicator (see below). Can a fix be provided by Bentley to correct this error? Please verify that this does not happen in the other design codes as well.
(SS6 v20.07.11.90, AISC 360-10)

Thanks,

Sorry I mislabeled the title, should be AISC 360-16 Truss Design Check. Unsure if Mods can update or not.
I would be interested in hearing about this as well. I am seeing the same thing. Can someone from Bentley comment on this?
Hey Jeremy,
Bentley got back to me on this through a Service Request. This was logged as Defect ID #976906 and is being resolved in the next update. The post-processing / design / output file are unaffected by what is shown in the Member Query box, and looks to only be affecting AISC 360-16. In essence, it's just a GUI error but the core results are correct.
To see the right results, they recommended to turn TRACK 2 on and view the critical forces in the Output file.
Thanks for the update!
I am having the same issue when checking to NZS 3404 - members that are utlised in tension only are being checked for axial compression also - leading to unrealistic URs >1.0. So it seems this bug still exists
