Abstract: A new procedure for calculating the effective width of stiffened elements with multiple longitudinal intermediate stiffeners is presented. The method determines the critical stress for distortional buckling of the entire ...

Abstract: The moment capacity of a laterally braced cold-formed steel flexural member with edge stiffened flanges (e.g., a channel or zee section) may be affected adversely by local or distortional buckling. New procedures for hand ...

Abstract: The objective of this paper is to investigate the behavior, and provide recommendations on, the design of open cross-section thin-walled cold-formed steel members that employ complex stiffeners. Complex stiffeners are ...
