为保证玻璃与与索网的协同变形，建立包含玻璃面板、索网、爪件、密封胶的有限元模型，真实反映了单层索网幕墙的传力途径；根据有限元模型，研究玻璃面板对单层索网静力性能和动力特性的影响；在此基础上，考虑索网幕墙周围建筑建立数值风洞，建立流固耦合模型，研究索网玻璃幕墙振动特性；以索网在平均风荷载作用下到达的新平衡位置为基准，采用频域方法计算单层索网风致动力响应。对比分析结果表明：风荷载作用下，索网幕墙主要做受迫振动，振动为窄带过程；玻璃面板有效降低了索网的平均位移和脉动响应。

In order to ensure glass deformation coordinated with a cable net,a FE model including a glass panel,a cable net,sealants,and spider was established to study the influence of glass panel on the static performance and dynamic characters of the cable net.The flowing field was simulated considering the buildings around the glass curtain wall.Based on those,fluid-structure interaction (FSI)analysis was performed to study the spectrum characteristics,dynamic response of the glass curtain wall.Under the average wind load,the cable net reached a new equilibrium position,the wind-induced response of the structure was studied with the frequency domain method.Comparison of two methods results showed that under wind load,the structure forced vibration is a narrow band process;the glass panel effectively reduces the average displacement and pulse response of the cable net.
