Abstract:Uniform constraint coefficient formulas used for various sections with different plate elements are given in the Current national specification "Technical Code for Cold-Formed Thin-Walled Steel Structure"(GB50018-2002).For the pressed flanges of cold-formed lipped channel flexural members,the coefficients of constraint action between plate components in distortional buckling mode are calculated by Direct Strength Method(DSM).The results calculated by DSM and GB50018-2002 are compared.Some valuable conclusions are drawn and can give reference to the research and design.
Keywords:cold-formed thin-walled lipped channel-section  distortional buckling  coefficient of constraint action between plate components  direct strength method
