[摘要] 框支剪力墙结构设计方案越来越普遍，但震害调查表明由于结构竖向刚度的不连续导致框支剪力墙结构容易在转换层附近发生严重破坏。通过采用具有延性好、承载力大等优点的钢-混凝土组合转换构件，可提高框支剪力墙结构的抗震性能。以某超限工程为背景，基于增量动力分析结果对结构进行地震易损性分析，建立地震动强度与结构失效概率之间的关系，评估结构超越各种极限破坏状态的概率。分析结果表明：在小震作用下结构保持基本完好，并未出现损伤；中震作用下结构产生轻度损伤，损伤仍处于可控范围；罕遇地震作用下结构发生严重破坏的概率为5.24%，结构抗震能力储备充足，能保障生命安全。

Abstract: The frame-supported shear wall structure was more and more widely used, but seismic damage investigation indicated that due to discontinuity of vertical rigidity, the nearby transfer story of frame-supported shear wall structure was severely damage. The adoption of steel-concrete composite transfer component with the advantage of good ductility and bearing capacity could improve the seismic performance of the frame-supported shear wall structure. The seismic fragility analysis based on an overrun practical engineering structure was carried out by adopting the incremental dynamic analysis method, and then the relationship between structure failure probability and ground motion intensity parameters were established. Results show that under frequent earthquake, the structure was in good condition and basically undamaged; under moderate earthquake, mild damages could be found in the structure which was still in the controllable range; under rare earthquake, the failure probability of serious damage was 5.24% ,which mean the structure was with sufficient anti-seismic capacity reserved.
Keywords: frame-supported shear wall；seismic fragility analysis；incremental dynamic analysis；seismic performance
