Abstract – This paper reports a numerical investigation concerning the buckling behaviour of cold-formed ferritic stainless steel stub columns under axial compression. The numerical model was developed by using the commercial Finite Element (FE) software ABAQUS 6.10. The developed FE model includes material, geometric non-linearities and geometric imperfections. The accuracy of the FE models have been evaluated by comparing the finite-element analysis results against corresponding experimental results of Cold-Formed Ferritic Stainless Steel Stub Column sections reported in the literature. After the verification of the finite element model parametric study have been carried out by varying the section geometries and the results have been compared with resistance predicted by continuous strength method(CSM). Based on the comparison of results valid conclusions are drawn.

Key Words – buckling; continuous strength method; finite element model etc.,
