| Abstract |
The purpose of this study is to evaluate the load carrying capacities of cold-formed steel members subject to combined axial load and bending moment. The solutions based on the standards (AISI specification and Eurocode3 part1.3 for thin-walled cold-formed steel design) and finite element analysis (ABAQUS version 6.5.1) results are compared with test results. A combined strength experiment is carried out using full-scale 24 specimens of lipped channel section with embossment in web. An eccentric axial load is applied in varying member-length and eccentric distance which produces an end-moment of the member. The finite element analysis considering geometrical and material nonlinearity has been used for the structural analysis. The load corresponding to the load limit point is taken as the failure load of the specimens. The predictions of the AISI specification, Eurocode and finite element analysis are compared with the experimental results, and it is shown that all of these analyses are reasonable on the whole in relation to the experimental results. |
