按新旧规范设计的多层住宅砖房地震易损性的对比

Seismic vulnerability comparison of multistory dwelling brick buildings between two generations of codes

本文采用概率方法借助于拉丁超立方采样技术和非线性地震反应时程分析对按现行规范设计的多层住宅砖房的地震易损性进行分析,并与按上一代规范设计的多层住宅砖房的地震易损性分析结果[1]进行了比较,为进一步研究这类结构的地震安全性、未来地震的损失预测以及防震减灾对策奠定基础。

In this paper, the seismic vulnerability of muhistory dwelling brick buildings designed according to the current codes is analyzed by Latin hypercube sampling technique and nonlinear seismic time history response analysis. And the seismic vulnerability results are compared with those of the buildings designed according to the former codes. The research lays the foundation for evaluating the earthquake safety, estimating the earthquake losses in the future, and finding the practical earthquake security.
