摘要
索穹顶结构优化设计分为三个方面 :预应力优化设计、截面优化设计、形状优化设计。通过线性规划、齿形法及模态搜索法的联合应用 ,内力分析采用有限单元法 ,预应力优化设计采用线性规划法 ,截面优化设计采用齿形法 ,形状优化设计采用模式搜索法 ,编制了索穹顶结构优化的计算程序 ,将索穹顶结构优化设计的三个方面有机地结合在一起 。
Cable domes structure optimization design consists of three aspects,prestress optimization design,section optimization design and shape optimization design.Linear programming,tooth method and modal search method is applied here. Finite element method is used for internal force analysis, liner programming method is used for the prestress optimization design ,the section optimization design adopts tooth method,the shape optimization design adopts modal search method.Computer program of the tensegrity cable domes structure optimization is complied and three aspects of optimization design is united organicly to solve the optimization solutions by cycling iteration.
