摘要
弦支穹顶作为一种新型的预应力空间结构形式,凭借其高效的传力机制和优美的外形效果,已在国内外近20项实际工程中得以应用。对现有工程的跨度、上部网壳结构形式、下部张拉整体部分形式、预应力施加方式、撑杆上节点和撑杆下节点等工程进行总结。在此基础上,对结构的预应力设计方法、节点设计、预应力张拉、模型试验等内容进行分析,提出一些可供工程参考的建议。
Suspen-dome structures,as new pre-stressing spatial structures,have been applied in about twenty projects in the world due to its highly-efficient structural mechanism and beautiful appearance.In this paper,some main information of suspen-dome projects were summarized such as span,type of upper dome,type of bottom tensegrity systems,pre-stressing method,upper joint of strut,bottom joint of strut and so on.Based on which,some analyses were carried out on the design method of pre-stressing,joints design,pre-stressing method and model tests,and some suggestions that would be a reference for projects were put forward.
