索桁架玻璃幕墙结构承载性能研究

Study on Loading Performances of Glass Curtain Wall Structure with Cable Truss

为了研究索预应力和玻璃刚度对索桁架玻璃幕墙承载性能的影响,论文分别对有玻璃面板参与协同工作和无玻璃面板参与协同工作的索桁架支承结构体系进行理论分析,在不同预应力作用下以及安装玻璃面板后施加水平荷载采用数值模拟的方法研究索桁架的承载性能。结果表明:索预应力越小,玻璃刚度的贡献作用越大;考虑玻璃刚度减小了索桁架变形,对索桁架幕墙的承载性能有所贡献。

In order to study the anchor pre-stress and grass rigid affected to the loading performances of the anchor truss grass curtain wall,the paper had a theoretical analysis on the cable truss support structure system with the grass panels and coordination work as well as the no grass panels coordinated work individually.Under the different pre-stress role and the horizontal loading added after the grass panels installed,the numerical simulation method was applied to study loading performances of the cable truss.The results showed that the smaller pre-stress on the cable,the higher contribution role of the grass rigid would have.Due to the grass rigid reduced the deformation of the cable truss,the grass rigid would have the contribution to the loading performances of the cable truss curtain wall.
