| 摘 要： | 空间张拉索穹顶整体结构是一类有无穷小机构位移的静不定且动不定结构，需要提供预应力完成几何整体性的构造．本文通过对预应力空间铰接体系的设计分析，提出了包括索和压杆的预应力优化设计方法，此方法是基于矩阵分析的柔性方法，它能够找到预应力和机构的状态且优化受压构件的预应力设计．

| Abstract: | Spatial tensegrtiy domes are a kind of statically determinate and kinematically determinate structure which has infinitesimal mechanism, which need Providing prestress to finish geometrical integrity construction. In this paper, according to the analysis of prestress spatial pin- jointed assembly design, a algorithm of prestress optimum design including cable and bar is presented. This method is based on matrix analysis and can calculate prestress and mechanism, which make members prestress obtain optimum rigidity. |
