［摘要］以某219.95m高超高層寫字樓為例，進(jìn)行了小震、中震反應(yīng)譜分析和大震動(dòng)力彈塑性時(shí)程分析。討論了不同加強(qiáng)層的設(shè)置對框架核心筒結(jié)構(gòu)在地震作用下的影響。結(jié)果表明，增加加強(qiáng)層數(shù)量，并采用剛度較小的環(huán)帶桁架方案，可以有效減小結(jié)構(gòu)變形，減輕結(jié)構(gòu)地震損傷情況，且不會引起結(jié)構(gòu)內(nèi)力和剛度的劇烈變化，抗震性能較好。

Abstract: Based on a 219.95 meters frame-core wall super high-rise structure, the structure model was analyzed by using response spectrum method under minor and moderate earthquake and by using dynamic elastic-plastic time history analysis under major earthquake. The impact of different strengthened storey setup schemes on frame-core wall under seismic action was discussed. The results show that increasing the number of strengthened storeys and adopting belt truss that has smaller rigidity can reduce the structural deformation and seismic damage efficiently, and the change of internal force and rigidity of the structure is small relatively. The structure performs well in seismic performance.
Keywords: framecore wall; strengthened storey; seismic action; response spectrum analysis; timehistory analysis
