幕墙抗震性能试验方法研究

幕墙抗震性能是结构性问题,本文认为,较合适的方法是建立合理的动力或等效静力模型进行分析,并结合试验验证其抗震性能;认为幕墙经合理设计能够抵风荷载作用时,抗震的焦点将集中在变形能力;认为模拟地震振动台试验方法是检验幕墙安全性的最准确,直观的方法,并提出了相应的试验建议。

Study on approach of earthquake resistance of curtain walls

Architectural curtain wall is non structural member,but its safety is of structural problem.To solve the problem,the reasonable approach is to establish the dynamic or static numerical model to analyze its seismic behavior and to access its earthquake resistance.On the other hand,test method is used to solve the problem as well.After proper design to resist wind loads,the earthquake resistance of curtain wall is focus on the deformation behavior under earthquake.Shaking table test is the most visual and precise method for the purpose,which can reproduce the earthquake waves and realize the earthquake actions.Some suggestions are put forward at the end of this paper.
