索穹顶结构的有限元法分析和张拉施工方法

Analysis on the Finite Element Method and Construction Method of Cable Dome Structure

回顾了全张力体系的概念以及索穹顶结构的发展历史 ,介绍了索穹顶结构的优缺点 .以有限元分析理论为基础 ,采用五节点空间曲线索单元的非线性有限元法分析推导了索穹顶结构的非线性位移关系、几何关系、物理关系、本构关系以及平衡方程 .最后结合模型和工程实际 。

The concept of Full Tensile System and developmental history of cable dome structure are reviewed. The structural virtues and shortcomings of the cable dome are introduced. Based on the theory of finite element, the relationship of nonlinear displacement, geometry, physics and equilibrium equations is analyzed and inferred by the use of nonlinear and finite element analysis about 'Five Entries Joints' dimensional curvilinear cell. Construction methods of open and draught are put forward in accordance with the model and actual project in the end.
