| 摘 要： | 针对索穹顶结构的优化设计现状，并从适合索穹顶结构工程应用的角度出发，本首先对选定截面情况下的预应力优化和选定预应力情况下的截面优化两种情况分别作了研究，然后采用分层优化法较有效地解决了截面尺寸与预应力同时优化的问题，得出了一些有用结论。

| Abstract: | Cable dome is a new type of space structure and the research on its optimal design is very important. In this paper, the optimum size and optimum prestressing force of cable domes are studied . To deal with the problem of matrix singular due to the different variables, a two-level algorithm is also developed. The result of numerical analysis shows that it is very effective to be used in the optimal design of cable domes. |
