摘　　要：本文从Marguerre平板大挠度应力协调方程出发,采用柱稳定函数作为位移函数,应用半解析法对有初曲薄壁槽形截面在常荷载偏心下的屈曲后性能进行了理论计算,得到了屈曲后平衡路径。理论与试验结果符合较好。In this paper, the solution of Marguerre's fundamental equations for large deflections of plain plates with slight initial curvature by using the semi-energy method of analysis is presented for thin-walled channel sections subjected to compression and bending. The computational cost compared with other methods is very economical. Good agreement is shown between experimental and theoretical results.
