摘　　要：在玻璃幕墙设计时,设计者都会注意考虑风荷载及地震作用效应,但却经常容易忽略其他因素的影响。幕墙结构上的热应力及其作用效果同样也是玻璃幕墙结构上非常重要的荷载形式,尤其是幕墙玻璃出现瑕疵或被切割时,会对玻璃幕墙结构产生致命的破坏。以某大楼玻璃幕墙破坏工程为例,利用有限元软件ANSYS的热应力分析模块对玻璃破坏的原因进行分析。其分析结果能为同类工程的检测提供参考,同时使后期的加固更具有针对性。When designing the curtain walls,most designers would consider wind load and seismic loads while ignoring other factors such as thermal stress which is also quite important especially when the glass with flaw is used or the glassis being cut.This article focuses on anslysing the reason of failure in curtain walls used in high-rise buildings by using the tool of ANSYS and combing the experience of an engineering example,hoping to provide some meaningful references for similar engineerings,get attention from most designers and reduce lost.
