摘要
从三条经典假设出发，采用加权残值法分析均匀受压冷弯薄壁槽形截面柱的局部相关屈曲．在分析过程中，应用配点法和五次Ｂ－样条函数计算，求得了较令人满意的结果，与已有文献结果比较，两者吻合较好。
Based on three classical assumptions weighted residual method is employed for analysing the local-buckling interaction of cold-formed thin-wall channel section subject to uniformed compression. Collocation method and quintic B-spline function are used in the study. The results of examples are satisfactory and coincide with those by others.
