摘要
分析研究了预应力网架和组合网架的结构性能及其计算方法。对预应力布索方案、预应力对结构的影响、预应力度及设计中的若干问题和指标作了探讨、分析和优化。
The structural properties of prestressed space grids and composite space grids are analysed in this paper. The methods of analysis, the layouts of high strength cables, the effects of prestressing on the structures, the controlled stress of the cables and several problems in the designs are also studied and optimized. At the same time, some suggestions for the designs are presented.
