摘　　要：本文采用非线性曲面膜单元和曲线索单元编制了膜结构内力计算程序 ,对实际制作的模型在风荷载和雪荷载作用下应力、位移的变化规律及皱折处理的方法作了研究 。In this paper, the nonlinear curved surface membrane element and curve cable element are firstly adopted to make computer program for the load analysis of membrane structures. Many useful rules such as how stress and displacement change under snow or wind load and how to treat element wrinkling have been obtained through the analysis of two scale models, which may give many helps to actual projects.
