A research on form－ finding methods of membrane structure

详细介绍了用于薄膜结构初始形态确定的力密度法和非线性有限元法等几种分析方法，并分别编制了相应的计算程序。本文运用各种分析方法对具体薄膜结构的算例进行了初始形态确定计算，对各种方法进行了分析比较。在此基础上提出了结合力密度法和基于非线性有限元的节点平衡法以确定薄膜结构初始形态的一种较为有效的方法——综合节点平衡法。

Some kinds of form－ finding methods of membrane structure such as force density method and nonlinear finite element method are carefully introduced. The relative calculation programs are compiled which can be used to analyze the initial form－ finding of membrane structures. Some calculation examples are done to analyze and evaluate by force density method and nonlinear finite element method. Based on the detailed research and evaluation, a new efficient form－ finding method— syn－ joint－ equivalence method is put forward.
