| 摘 要： | 索网是一种典型的空间柔性结构体系,必须通过施加预应力的方法才能形成有效刚度.预应力的分布则需要通过形态分析(找形与找力)来完成.对找力分析的两种方法--复位平衡法和逆迭代法进行研究,分析了这两种方法的基本思路和算法.结果表明:对大型索网结构,通过找力分析可以得到满足给定形状的预应力分布.

| Abstract: | Cable net is a typical kind of flexible space structure,the effective stiffness must be formed by prestress.The distribution of the prestressed need be finished through morphological analysis.The force reduction equilibrium method and inverse iteration method are studied,the basic thought and algorithm of the two methods were analyzed.The results indicate that the given shape of prestress distribution can be obtained for large cable network structure by finding force. |
