Has anyone else seen the 1/7/09 "Pearls Before Swine" newspaper comic strip, which goes:
Interviewer (pig): "What are you doing, Rat?"
FLR: "I am Frank Lloyd Rat, Master Architect, and this is a scale model of my latest masterpiece, an office building made of nothing but rotating cheese."
Engineer: "This could be really hard to build."
FLR: "My engineer is quite lame."

There is another relatively painless method contained in Design of Welded Structures by Blodgett.

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
