摘　　要：通过调整某异形柱框架-剪力墙结构的剪力墙布置方案,进行改进后模型的模态分析和弹性时程分析,研究剪力墙和异形柱不同平面布置对地震响应的影响。分析发现,改进后模型的抗震性能显著提高,底部剪力变化不大,最大楼层位移和结构自振周期得到明显改善,最大楼层位移值减小14.4%,自振周期减小4.34%。The layout of shear-walls of an actual RC frame-shear wall structure had been adjusted, and then methods of modal analysis and time-history analysis were used to study the effect of different layouts of shear-walls and specially shaped columns on the structure under earthquake. After analysis, it is found that the seismic behavior of the adjusted model has improved obviously when having slightly variations of shear value at the bottom of structure. The maximum story displacement and natural period are reduced most apparently by 14.4% and 4.34%.
