Abstract
Stainless steel has strong corrosion resistance and durability, which ensures the structural safety and durability, and has a good application prospect. Experiments on stainless steel have shown that the stress-strain nonlinearity of stainless steel is remarkable, which is different from that of ordinary steel. At present, the technical specifications for stainless steel structures do not specify the analysis of the internal force of stainless steel frames. By comparing the design specifications of steel structures and using finite element analysis method to analyze the internal forces of stainless steel frames, it is concluded that the approximate second-order analysis method in the design specifications of stainless steel frames can not be used, and the second-order analysis of internal forces of stainless steel frames should be carried out in consideration of material nonlinearity.
