...there is a free light gage steel design program by Clark Western
( that is relatively simple and easy to use.

-----/Original Message/-----

I strongly advise not relying on any such program (and yes, I am
familiar with the Clark software) without first doing a few typical
examples of design (flexure, axial compression, connections, e.g.) by
hand first. There is an acute danger in complacent reliance upon such
software, because it obscures some of the nuances of cold-formed steel
design (the current "proper" designation for this material).

For example, there are some aspects of design for stability, especially
in flexure, in CFS design that are more than "trivial" due to the nature
of the thin elements used. Don't just assume that "it's just like
'regular' steel design."

Get familiar with it first, before "automating" any such designs.
