[摘要] 基于動力增量時程分析法的結構易損性分析是基于性能抗震設計的重要內容。本文重點分析了不同抗震設防烈度下三層RC框架結構遭受地震動破壞時的情況，統(tǒng)計得出了相應的破壞概率矩陣與結構易損性曲線；建立了設防烈度與破壞概率之間的關系，為設計人員確定結構抗震性能水準提供了數據支持。

Abstracts：Seismic vulnerability analysis based on IDA is the most important content of performance-based seismic design. A three-storey frame structure designed under different seismic fortification intensity were analyzed when Subjected to seismic damage in this paper, the statistics show that the corresponding destruction probability matrix and structural vulnerability curve; The relationship fortification intensity and failure probability were founded, and it can give the designers support data when determining the structural seismic performance level .
Keywords：vulnerability；IDA；frame structure
