| 摘 要： | 弦支穹顶结构是一种新型结构体系,它综合了单层网壳结构和索穹顶结构各自的优点.为全面认识弦支穹顶结构在地震作用下的动力稳定性问题,本文以具有实际工程意义的50m跨度凯威特型弦支穹顶结构作为研究对象,系统分析了多种因素对弦支穹顶结构动力稳定性临界荷载的影响,其中包括:不同支座条件、不同矢跨比和不同杆件截面、不同拉索布置层数、不同拉索预应力值以及不同地震输入.本文成果为弦支穹顶结构的工程应用提供有价值的参考.

| Abstract: | As a new type of structural form,the suspend dome structure combines both benefits of the single layer reticulated shell structure and the cable-dome structure.To investigate the dynamic stability behavior of the suspend dome structure under earthquake excitation,suspend domes with a span of 50 m are taken as examples and a comprehensive numerical analysis on dynamic stability behavior of some proto-type suspend domes is carried out with the following primary parameters: boundary conditions,rise-to-span rat... |
