采用Pushover能力谱分析方法针对典型三层和六层RC框架结构进行易损性分析，分析时采用层间位移角作为整体性能指标，建立了易损性曲线和易损性矩阵。结果表明，强震作用下三层RC框架结构发生各破坏等级的概率均低于六层RC框架结构，分析得出的易损性矩阵与根据实际震害得到的易损性矩阵吻合较好，验证了该方法可靠且简便易行。
採用Pushover能力譜分析方法針對典型三層和六層RC框架結構進行易損性分析，分析時採用層間位移角作為整體性能指標，建立瞭易損性麯線和易損性矩陣。結果錶明，彊震作用下三層RC框架結構髮生各破壞等級的概率均低于六層RC框架結構，分析得齣的易損性矩陣與根據實際震害得到的易損性矩陣吻閤較好，驗證瞭該方法可靠且簡便易行。

This paper adopts Pushover capacity spectrum analysis method of vulnerability analysis for the typical three-layer and six-layer RC frameworks,using the inter-story displacement angle as the overall performance index analysis,establishes fragility curves and the seismic vulnerability matrix. Results show that the probability of each damage level that occurs in three-layer RC frame structure under strong earthquake is lower than the six-layer RC frame structure,the obtained analysis of vulnerability matrix is in good agreement with the obtained vulnerability matrix from the actual earthquake damage,which proves the reliability and easy accessibility of the method.
