What programs or references are recommended?
Curious if a hat section about 4" deep is stronger in bending with the top fibers in tension or compression?

It really depends on how the supports are arranged, and the sheetings laid - continuous over several supports, or simply supported between two.

This also brings up the unbraced factors Lx,Ly, and Lt. If the purlins are 4' apart, are the unbraced lengths all equal to 4'? The roof covering will be a fabric or polycarb covering with 4-6' spacing between rafters.

Kind of off topic but I went to a short course on cold formed steel design put on by the Univ. of Missouri
www.ccfssonline.org
3 day course, intensive, and got a free textbook out of it. I think it is offered twice a year.

Hat Channels are generally for furring and ceilings (non-structural)

I would agree with your assessment on the Short Course.
However, it is an every odd year offering, alternating with an International Cold-Form Steel Conference in St. Louis in the even numbered years.

Also, how are the Saint-Venant torsion (J) and warping constants (Cw) calculated?
Does anybody use the CFS or RAM software fairly regularly for cold formed design? If so, do you have any recommendations or tips for the software? Thx
