weak axis bending for a channel lintel
weak axis bending for a channel lintel
(OP)
Are there any additional manuals available that provide a better analysis of weak axis bending for steel channels? ASD does not address the bending stress for this shape. I have a 12' opening and am trying to decide if an I beam may be needed instead.

AISC allows the use of 0.75Fy for weak axis bending stress for I, H shaped sections, rectangular plates and solid bars. See equation F2-1. This is due to the fact that these members tend to fail in yield and not buckling.
However, to be on the conservative side, I would use equation F2-2 (0.6Fy) for a channel.
