Combined Axial and Bending Stresses

Combined axial and bending stresses in cold-formed sections can be handled the same way as for structural steel. The interaction criterion to be used is given in the AISI Specification for the Design of Cold-Formed Structural Members.
Cold-formed members may be assembled into desired shapes or spliced or joined to other members with any of various types of fasteners. For the purpose, welds, bolts, and screws are most frequently used, but other types, such as rivets, studs, and metal stitching, can also be used.
