摘　　要：对气承式膜结构在构造及正常使用上的一些特殊性进行了说明。采用非线性有限元方法对气承式膜结构进行初始形态分析,编制了相应的程序。对该类结构形式典型算例进行了初始形态分析,并将计算结果与解析解和通用有限元分析软件Ansys计算结果进行了校核,验证了所编程序的正确性。The particularities of construction and normal service of air-supported membrane structures are discussed in detail. The way of form finding of air-supported membrane structures form is analysed using nonlinear finite element method with the corresponding computer program compiled. Some typical air - supported membrane structures are calculated. And its accuracy and adaptability have been testified by comparing the results with analytical results and results of ANSYS software.
