Abstract: Global buckling modes of cold-formed steel (CFS) unequal-leg plain angle (UPA) compression members are flexural–torsional buckling (FTB) modes due to their nonsymmetric cross section. Although the behavior of CFS equal ...

Abstract: Lip stiffened flanges in cold-formed steel compression members may undergo local or distortional buckling depending on the slenderness of the flange and rigidity of the lip. In distortional buckling, the flange-lip assembly ...
