The flexural-torsional buckling behavior of cold-formed steel beams is very complicated at elevated temperatures and a good understanding and knowledge of the topic is very *** considerable research has been conducted on the flexural-torsional buckling behavior of hot-rolled steel members and stainless steel beams at elevated temperatures,It is necessary to study the cold-formed steel members at uniform and non-uniform elevated *** Direct Strength Method(DSM)may be to calculate the distortional buckling strength of steel cold-formed thin-walled(CF-TW)members with uniform and non-uniform elevated temperature *** assessment is carried out by checking the DSM calculation results with numerical simulation *** paper proposes a modification to the distortional buckling curve to enable DSM to deal with distortional *** columns with non-uniform temperature distributions.
