x-brace member check&select using staadpro per asce 10-97
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!

check out our whitepaper library.
what do you mean "can't identify x-bracing"? if you want to analyse tension-only members, then you need to designate one diagonal inactive for one set of lateral loads, analyze, code check, restore the members and reverse inactive
thanks for ur interest.

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
i don't know anything about asce 10-97. maybe i should look into it.
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.
