Abstract

Abstract

Test results of the stainless steel material property indicate that: considerable difference exists among different states of the same type stainless steel and also exists among varieties of type.However this difference is not directly considered in the typical design codes existing in the world.Based on the verified FEM model,total 30 column curves are calculated that covered the range of material properties in common use.The concept of modification slenderness ratio is utilized to modify the Perry formula and the K＆R formula; at last,new design formula is obtained for calculating the buckling strength of stainless steel columns.Comparisons between the available test result and the proposed approach are conducted.The comparisons indicated that the proposed approach could fit the test results well.This approach could be used as a reference for the first version of stainless steel design code of China．
