 ［摘要］以某219.95m高超高层写字楼为例，进行了小震、中震反应谱分析和大震动力弹塑性时程分析。讨论了不同加强层的设置对框架核心筒结构在地震作用下的影响。结果表明，增加加强层数量，并采用刚度较小的环带桁架方案，可以有效减小结构变形，减轻结构地震损伤情况，且不会引起结构内力和刚度的剧烈变化，抗震性能较好。

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: framecore wall; strengthened storey; seismic action; response spectrum analysis; timehistory analysis
