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%.Keywords:specially shaped column frame-shear wall structure; modal analysis; elastic timehistory analysis; story displacement吉林省教育廳科技計(jì)劃項(xiàng)目(200630);吉林市科技發(fā)展計(jì)劃項(xiàng)目(200702)。作者簡(jiǎn)介:秦力,博士,教授,Email:jilinql@163.com。參考文獻(xiàn)[1]徐培福.超限高層建筑結(jié)構(gòu)基于性能抗震設(shè)計(jì)的研究[J]. 土木工程學(xué)報(bào),2005,38(1):1-10.[2]FEMA 356(2000) Prestandard and Commentary for the Seismic Rehabilitation of Buildings[S].
