国内一些文献已经对索穹顶结构的静动力性能进行了一些研究,但涉及的参数比较单一,未能充分揭示其特性。本文运用空间非线性两节点直线杆单元和悬链线单元模拟索穹顶结构中的压杆和长索,对Geiger体系索穹顶结构进行全面参数分析(包括温度、预应力水平、构件截面面积、结构形体),得出了一些有益的结论,可以指导以后的索穹顶结构设计。 Some domestic literatures have done some research on the static and dynamic performance of the cable dome structure, but the parameters involved are relatively single, which can not fully reveal its characteristics. In this paper, a comprehensive parametric analysis of cable dome structure of Geiger system (including temperature, prestress level, cross-sectional area of ​​component, structure Body), come to some useful conclusions, can guide the future cable dome structure design.
