Good day,
Is there a way to have STAAD check two different deflection checks for two different load envelopes?
I tried to create two serviceability envelopes and assign to two different parameters. see below. I also tried other ways but nothing worked for me. Looks like STAAD can only perform a single deflection check? Thanks.
