摘　　要：针对现行幕墙设计规范没有明确规定单层平面索网幕墙体系的风载荷计算的问题,以某大厦裙房幕墙为研究对象,用ADINA分析考虑流固耦合作用的玻璃-索网体系风振响应分析,并与通常采用的等效静风载荷方法得到的结构风效应比较.分析表明,对于非线性的索网玻璃幕墙结构,现行载荷规范采用的等效静风载荷方法会导致偏于不安全的设计计算结果.As to the issue that the wind load calculation on single-layer plane cable network curtain system is not clearly defined in the current curtain design specifications, the curtain of a building podium is taken as the research object, the wind-induced vibration response of the system of glass vs cable network is analyzed considering fluid-solid coupling by ADINA. The results are compared with the results of the structural wind effect obtained by the usual equivalent static wind load method. The analysis indicates that the equivalent static wind load method which is used in the current load specifications may lead to unsafe design and calculation results for the nonlinear structures of single-layer cable network glass curtain walls.
