STAAD.pro v8i and Torsion
(OP)
I am working on a pipe rack made with channel stringers. I have entered known torsional moments in the stringers. It is unclear to me in the steel design output whether the code checks include this torsion. Does STAAD automatically check members including torsion or do I need to define a parameter or something so that STAAD knows to run this check.

That should do it. STAAD currently checks torsion by the 9th edition. The "Track 2" command will give you detailed info in the post-processing file on the warping stresses, code check, and so forth.
