摘　　要： 论述了张拉膜结构找形分析的力密度法,同时对边界索进行T单元的强化处理;建立了索边界主结点和索网内部T单元结点的静力平衡方程,据此编制了相应的计算软件;对工程实例进行了验算,结果表明,给出的计算结果与德国著名软件EASY的计算结果相吻合。 In this paper, the force-density method is used to analyze the initial shapes of tension membrane structures, in which the boundary is treated with T-element. The static equilibrium equations for the main nodes on the cable boundary and the T-element node in the cable net are obtained and solved. A computer program is accomplished. Some numerical results of a practical example are given and compared with that of EASY code. It is found that the results obtained using the present method are in good agreement with that of EASY.
