| 摘 要： | 采用应力等效方法，将膜面离散成索网进行研究．根据索网结构的特点，直接建立了自由节点的平衡方程．再由平衡方程分别推导了应用于膜结构找形以及荷载分析的计算公式，并对等应力面以及褶皱等膜结构计算中的问题进行了讨论．最后编制了膜结构找形及荷载分析程序，并通过算例证明了文中方法的可行性．

| Abstract: | The membrane structure is first discreted into the cable-net structure according to the method of stress equivalence. Next, for a cable-net stru cture, nodal equilibrium equations of free nodes are directly established, accor ding to which formulas for the form-finding and loading analysis of the membran e structure are individually derived. Then, the isostress surface assumption and wrinkle problem of the membrane structure are discussed. A program for the form -finding and loading analysis of the membrane structure are finally developed. Some examples verify the feasibility of the proposed methods. |
