摘要

A large deflection elastic-plastic analysis has been developed using the finite strip method to determine the nonlinear local buckling behavior of cold-formed sections in compression. The analysis accounts for plate geometric imperfections, the variation of yield stress around a section, the stress-strain characteristics of the material forming the section and the highly complex patterns of residual stress produced by the cold forming process. The nonlinear overall buckling behavior of members can also be analyzed with a modification to the displacement functions in the finite strip analysis. The analysis is verified against reliable solutions for the nonlinear local buckling behavior of plates and plate assemblies in axial compression and bending, and the nonlinear overall buckling behavior of a strut. The effect of the high levels of residual stress present in these sections is demonstrated using the finite strip analysis.
