I am assuming that calculations are performed, only not submitted. Is this
the case? How else can you know the demand against the structure laterally
and gravity load. Are gravity load members designed by prescriptive tables?
What about the design of Chords, Drags and Struts - especially in buildings
with re-entrant corners?
Can some explain this to me as I must be missing something of importance
