[摘要]  建筑结构抗震易损性分析是基于性能抗震设计的核心目标。首先根据我国现行框架结构破坏状态的判定标准，对典型框架结构的破坏状态指标量化进行了研究；其次，通过动力增量时程分析法，分析了一组不同层数框架结构遭受地震动破坏时的情况，统计得出了相应的破坏概率矩阵与结构易损性曲线；最后通过研究易损性分析结果，讨论了现行规范下建筑层数对抗震性能的影响并针对结构抗震设计给出了相关建议。

Analysis on structural seismic vulnerability of RC frames with different building storey number

（1 Inner Mongolia Technical College of Construction，Hohhot 010070, China; 2    ）

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
