冷弯型钢构件设计的关键问题之一是轴压下的局部屈曲强度。本文主要研究相邻板单元宽厚比不同的矩形截面和唇形C型截面构件的局部屈曲强度，通过数值分析研究其弹性和非弹性局部屈曲强度。通过将数值分析结果与传统设计方法的结果进行比较，我们发现相邻板单元之间的板约束效应同时影响冷弯型钢构件的弹性屈曲强度和最大强度。
One of the key issues for the design of cold-formed steel members is the local buckling strength under axial compression. In this paper, we focused on the local buckling strength of rectangular section and lipped -C section members whose adjacent plate elements have a different width-thickness ratio, and investigated their elastic and inelastic local buckling strength through the numerical analysis. By comparing the numerical analysis results with that obtained from a conventional design method, we found that the plate restraining effect between adjacent plate elements affected both the elastic buckling strength and the maximum strength of cold-formed steel members.
