Abstract: The direct strength method (DSM) simplified the design of cold-formed steel (CFS) beams and columns compared with the traditional effective width method (EWM). In this paper, DSM equations for the distortional buckling ...

Abstract: The strength of thin-walled cold formed steel (CFS) lipped channel compression members may be governed by yielding, local, distortional, or global buckling or any possible interaction among these buckling modes. The ...

Abstract: The axial compressive strength of the cold-formed steel (CFS) members with edge or intermediate stiffener is affected by interaction of local, distortional and overall buckling. In order to overcome the tedious and time ...

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 ...
