| 摘 要： | 运用力密度法对索膜结构找形的关键问题是结构的离散．本文将一种离散方法运用于索膜结构的力密度找形分析，取得了很好的效果．计算结果与理论值及用非线性有限元方法所得结果进行了比较，证明该方法在保持力密度法收敛速度快的同时，精度也足够高．

| Abstract: | Dispersion is the key problem of form-finding of cable and membrane structures using force density method. A new approach of dispersion with force density method in form-finding of cable and membrane structures are presented in this paper. This new approach is approved to be valid by comparing of the theoretical value and the results from nonlinear finite element method. |
