[摘要] 建筑結構抗震易損性分析是基于性能抗震設計的核心目標。首先根據(jù)我國現(xiàn)行框架結構破壞狀態(tài)的判定標準，對典型框架結構的破壞狀態(tài)指標量化進行了研究；其次，通過動力增量時程分析法，分析了一組不同層數(shù)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；最后通過研究易損性分析結果，討論了現(xiàn)行規(guī)范下建筑層數(shù)對抗震性能的影響并針對結構抗震設計給出了相關建議。

Abstracts: Structural seismic vulnerability analysis is the most important objective of performance-based seismic design. First of all, according to the current criteria to judge the frame structure damage state, the index quantification of typical frame structure damage state are studied; Secondly, through the incremental dynamic analysis method, a group building of frame structure with different layers is analyzed when Subjected to seismic damage, the statistics shows that the corresponding destruction probability matrix and structural vulnerability curve; Finally, through studying the vulnerability analysis results, this paper discusses the influence on the seismic performance with different building storey number of current standard and suggestions about structure seismic design are given.
Keywords: RC frames; seismic vulnerability; IDA
