The only reference that quickly comes to my mind is AISC's "Torsion Analysis of Steel Members".

List members: I have a curved beam (horizontal). The center line of the beam layout is horizontally offset from the supporting post by about 10+ % of the span. The arch wants a channel section and will not allow a tube section. Can anyone suggest a quick method to check for flexure and torsion. DL is 480plf , LL = 800 plf. The project in under construction and the detail is due first thing to-morrow morning. Gautam |
