[摘要] 框支剪力墻結(jié)構(gòu)設(shè)計(jì)方案越來(lái)越普遍，但震害調(diào)查表明由于結(jié)構(gòu)豎向剛度的不連續(xù)導(dǎo)致框支剪力墻結(jié)構(gòu)容易在轉(zhuǎn)換層附近發(fā)生嚴(yán)重破壞。通過(guò)采用具有延性好、承載力大等優(yōu)點(diǎn)的鋼-混凝土組合轉(zhuǎn)換構(gòu)件，可提高框支剪力墻結(jié)構(gòu)的抗震性能。以某超限工程為背景，基于增量動(dòng)力分析結(jié)果對(duì)結(jié)構(gòu)進(jìn)行地震易損性分析，建立地震動(dòng)強(qiáng)度與結(jié)構(gòu)失效概率之間的關(guān)系，評(píng)估結(jié)構(gòu)超越各種極限破壞狀態(tài)的概率。分析結(jié)果表明：在小震作用下結(jié)構(gòu)保持基本完好，并未出現(xiàn)損傷；中震作用下結(jié)構(gòu)產(chǎn)生輕度損傷，損傷仍處于可控范圍；罕遇地震作用下結(jié)構(gòu)發(fā)生嚴(yán)重破壞的概率為5.24%，結(jié)構(gòu)抗震能力儲(chǔ)備充足，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
