Ultimate strength of C-shaped cold-formed steel members in compression and major axis bending
Effective section method (ESM) is widely used in the design of cold-formed steel structures.However,the influence of distortional buckling of members was hot considered.A new method for the load carrying capacity of cold-formed steel members,direct strength method (DSM),can effectively estimate the ultimate strength for local,distortional buckling and interactive buckling.However,it is not used for beam-columns.The stability behavior of C-shaped cold-formed members eccentrically compressed around the major axis was analyzed.The effects of Length of member,eccentricity and width-thickness ratio of webs,flanges and edge stiffeners on ultimate strength of members were examined in this study.A calculation method of ultimate strength was proposed based on the original DSM axial compression/bending formulas and the finite element analysis results.
