摘　　要：合肥高速·滨湖时代广场C1#塔楼北立面在其高度为220m处设置有尺寸为27m×44m的单层平面索网幕墙,具有超高层、超大空间特征,风荷载作用时平面外变形较大,其安全问题显得尤为突出。为此,制作了缩尺比例为1:10的无玻璃和有玻璃两种模型,分别对两种模型进行了面外静力加载试验,分析了其在均布静力荷载作用下的平面外变形和拉索内力等静力性能。试验结果表明:有玻璃模型结构满足规范对单层平面索网幕墙风荷载作用下平面外变形要求,具有较高的安全性,玻璃对平面索网幕墙的刚度具有一定的贡献。最后,采用ANSYS有限元软件对试验过程进行模拟,并通过对比数值模拟结果和试验数据,验证了数值模型的正确性。A single-layer plane cable net curtain wall measuring 27m×44m is placed on the north facade of Hefei Highway Lakefront Times Square C1#building at the height of 220m.This curtain wall is featured with super high-rise and large space and the out-of-plane deformation is large when wind load acts,and its safety problem is particularly prominent.For this reason,two test models with a scale ratio of 1∶10,one with glass and one without glass,were produced and out-of-plane static loading test were carried out on the two models respectively.The static performance of the out-of-plane deformation and internal force of the cable under uniform static load were analyzed.The experimental results show that the glass model structure meets the requirements of the specification for the out-of-plane deformation of the single-layer plane cable net curtain wall under wind load,and has high safety.Glass has a certain contribution to the rigidity of the plane cable net curtain wall.Finally,the ANSYS finite element software was used to simulate the experimental process,and the correctness of the numerical model was verified by comparing the numerical simulation results with the experimental data.
