To investigate its seismic performance under earthquake, a shaking table test for its 1/30 scale model was carried out. The dynamic characteristics of the structure and its dynamic responses under different levels of earthquake were studied. Using the shaking table test data and the observed cracking pattern, seismic performance and failure mechanism of tested model were studied. The weakness parts of the structure were investigated and the suggestions and measures to improve the seismic ability were presented.Keywords:shaking table test; high-rise buildingsbeyond the code\|specification; seismic performance; seismic response*武漢市建委科技項(xiàng)目(200839)。作者簡介:李書進(jìn),教授,Email:lishujin@yahoo.com。參考文獻(xiàn)[1]JGJ3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京:中國建筑工業(yè)出版社,2002.[2]李書進(jìn),陳玉璽,周強(qiáng),等. 超限高層建筑整體結(jié)構(gòu)模型振動(dòng)臺(tái)試驗(yàn)設(shè)計(jì)[J]. 工業(yè)建筑,2009,39(S1):222-226.[3]GB50011—2001 建筑抗震設(shè)計(jì)規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2001.[4]李檢保,呂西林,盧文勝,等. 北京LG大廈單塔結(jié)構(gòu)整體模型模擬地震振動(dòng)臺(tái)試驗(yàn)研究[J]. 建筑結(jié)構(gòu)學(xué)報(bào),2006,27(2): 10-15.[5]呂西林,鄒昀,盧文勝,等. 上海環(huán)球金融中心大廈結(jié)構(gòu)模型振動(dòng)臺(tái)抗震試驗(yàn)[J]. 地震工程與工程振動(dòng),2004,24(3): 57-63.[6]李永雙,徐自國,曹進(jìn)哲,等. 某高層住宅項(xiàng)目振動(dòng)臺(tái)試驗(yàn)研究及彈塑性分析[J]. 建筑結(jié)構(gòu),2009,39(3): 47-50.[7]LI C S, LAM S S E, ZHANG M Z, et al.
