摘　　要：为了研究索预应力和玻璃刚度对索网幕墙承载性能的影响,参考北京新保利大厦二期工程,进行了1∶10比例的点支式玻璃幕墙单层索网模型试验.试验中分三级对索网进行预应力施加,在各级预应力下以及安装玻璃后施加水平荷载研究索网的承载性能,并和有限元计算结果进行对比.试验结果表明:水平荷载越大,增加索网预应力对降低索网变形的作用相对越小;考虑玻璃刚度减小了索网变形和索内力,对索网幕墙的承载性能有所贡献.In order to study the influence of prestress and glass stiffness on the loading capacity of monolayer cable net for point supported glass curtain wall, an experiment on 1 ： 10 scale model according to Beijing New Poly Plaza was carded out. The process of pretension was simulated in three steps. Horizontal load was applied to the cable net under different prestress and with the glass so that the loading capacity of the cable net could be researched. The results of experiment and finite element calculation were compared. The experiment results show that the larger the horizontal load, the less the effect of prestress increasement on descending deflection of cable net. The stiffness of glass contributes somewhat to the loading capacity of the cable net since it reduces the deflection and force of the cable net.
