摘　　要：金沙遗址采光屋顶采用预应力悬索结构,结构形式新颖。基于ANSYS 10.0对该结构进行了结构设计及找形分析,确定了悬索结构的结构选型和构件截面及要施加的预应力值。在此基础上,对结构施工阶段和正常使用阶段的全过程受力性能进行了研究分析,并结合现场实测结果,分析了预应力张拉完成及玻璃安装完成后两种状态下的钢索索力差异,并提出了此类结构的设计方法和施工方法,可供类似工程参考。The suspended-cable structure is used for the day-lighting ceiling of jinsha site. The structural configuration is a modern design. Structural design and analysis of form-finding are carried out using ANSYS 10.0.The structural forms, member cross sections and the amount of prestressing of the string structure are determined through synthetic analysis. On this basis, the behaviors of the BSS during the construction period and the serviceability phases are analyzed and investigated. According to the constrution monitoring result ,the difference of cable force is analysed after prestressing tension and glazed work. The methods of structural design and construction are proposed. Which may be a reference for other similar projects.
