摘要
建筑幕墙属于非结构构件 ,但其本身的安全问题却是结构问题。本文对幕墙抗震性能进行了探讨 ,认为幕墙单元应满足加速度和层间位移反应的检验标准 ;模拟地震振动台试验方法能够再现真实的地震作用 ,是检验幕墙安全性最准确直观的方法。本文采用该方法对某花岗岩幕墙进行了试验研究 ,验证其抗震性能。
Architectural curtain wall is not a structural member, but its safety is a structural problem. The earthquake resistance behaviors of the curtain wall are discussed in this paper. The safety of the curtain wall under earthquake must be verified in two aspects, i.e. acceleration response and story drift. Shaking table test for simulating earthquake is the most visual and precise method for the purpose, which can reproduce the seismic excitations and realize the earthquake actions. A granite curtain wall is tested and analyzed in the paper.
