Abstract

Abstract

ANSYS is employed to study the overall buckling properties of stainless steel cold formed tubular columns under axial load.Non-linear property of material,the effect of cold-formed,local and overall imperfection as well as the residual stress are considered in this model.The comparisons between test results and the calculated results are performed in order to verify the FEM model.Comparisons indicate that the developed FEM model could represent the test exactly and the deviations in average are limited in 5%. Then the influences of varieties of factor are valued.The results of parameterized analysis conclude that: the influence of the increase strength in the corner region,the parameters variation of the material property and the amplitude of the overall imperfection could cause considerable changes in the buckling strength of stainless columns; shifts in section types almost do not influence the buckling strength.The conclusion could be regarded as the foundation of the design method for cold-formed stainless steel columns．
