| 摘 要： | 钢结构是近年来工业建筑较多采用的一种建筑形式,但是一直以来缺乏该类建筑的地震破坏数据。考虑了地震动的随机性和不同场地条件下建筑物震害的差异,给出了一种该类建筑地震灾害风险评估的方法;以上海某机械有限公司单层钢结构车间为例,对其进行了多地震非线性动力时程分析。利用分析的结果,结合地震破坏指标给出结构的震害率曲线。该曲线可以预测同类建筑的震害,为城市抗震防灾政策的制定提供依据。

| Abstract: | It is difficult to estimate the seismic damage of steel structural workshop due to lack of the seismic damage data on this kind of building.It is presented an analytical method for the seismic hazard assessment on steel structural workshops.A single-layer steel structural workshop in Shanghai was analyzed using the nonlinear time-history method.A seismic fragility curve is presented according to the seismic damage index.The developed hazard curves can be used for predicting seismic risks of similar buildings,which provides a basis for making the policy of urban antishock and damage prevention. |

| Keywords: | seismic risk assessment hazard curves damage index elastic-plastic analysis steel structural(workshop) |
