X-brace member check&select using STAADPRO per ASCE 10-97
X-brace member check&select using STAADPRO per ASCE 10-97
(OP)
I've utilized STAADPRO to check&select X-brace members of a tower per to ASCE 10-97. But it seems that STAADPRO can't identify the X-brace members.
So I wonder whether the software be able to identify X-brace members automatically. If it can, how to achieve it?
Thanks ahead!

This can all be done in one run.

The X-brace system in a steel tower is designed as tension/compression system.
According to ASCE 10-97 (see page 58), for one member in the X-brace members under compression/compression, different length "L" (kL/r) should be taken depending on the other memebr's compression/compression status. Hereof,in some status, the length L1 (from one endpoint to crosspoint) should be used.
I wonder whether STAAD can idtify the length under different status automatically.

However, from your description, I think what you want to do is set up 2 separate "code checks" or 2 separate "selects". You can change the effective length K factor for each code check. I think that you would want to use the load list command to restrict which loads or load combinations are used for which code check.
