摘　　要：弦支穹顶是由上部单层网壳和下部预应力索杆体系组成的空间结构。结合体育馆屋盖的设计,对采用的弦支穹顶结构进行始态、荷载态、地震作用分析。讨论弦支穹顶设计的基本过程,并对索所需的预应力大小进行分析设计。计算结果表明,弦支穹顶结构具有良好的受力性能和经济性能,满足建筑造型的要求。The suspendome is a type of spatial structure composed of the single-layered grid shell and the prestressed cable strut system. Based on the design of a gymnasium roof, the loading behavior of the suspendome has been investigated in this paper, including the initial state analysis, load state analysis, as well as seismic action analysis. The process of the design of the suspendome has been analyzed, and the values of prestress in the cables were designed. The results indicate that this form of suspendome has good loading performance and economic efficiency, and can meet the requirements of the modelling of an architecture.
