摘要
张拉结构的找形问题是张拉结构分析中的关键问题,张拉结构的找形一般可以分为两类:(1)结构预张力分布已知,结构初始几何未定,所要求解的是结构初始态几何位置;(2)结构初始几何已知,预张力分布未定,所要求解的是给定结构几何下的预张力分布。本文以这两类问题为主线对当前张拉结构的主要找形方法进行了较为详细的介绍,可为该领域的科研人员提供参考。
Form finding is the key problem of tensile structure in the structural analysis. The Form finding method of tensile structure can be grouped into two categories ： 1 ） the distribution of prestress is pre-known and the geometry of the equilibrium state is to be found; 2） the geometry of the equilibrium state is pre-known and the distribution of the prestress is to be found. Based on above groups, this paper provides a detail introduction of the form finding methods for the tensile structure and can give an overall view to the researchers on this field.
