Connecting method of steel corridors between the main structures of tall building can be rigid or flexible. The flexible connections of corridor can improve the dynamic performance and seismic behavior of the structure. The peak acceleration of human-induced vibration of long span floor structure was calculated and comfort evaluation was conducted. Results show that the main structures have well seismic performance and the dynamic response could be improved by the corridor with flexible connections.Keywords: connecting corridor; flexible connection; lead-rubber bearing; comfort; seismic performance作者簡介:姜擁軍,工程碩士,高級工程師,一級注冊結(jié)構(gòu)工程師, Email: jiang.yongjun@163.com。參考文獻(xiàn)[1]GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范[S].北京:中國建筑工業(yè)出版社,2010.[2]JGJ 3—2010 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,2011.[3]呂西林.超限高層建筑工程抗震設(shè)計(jì)指南[M].上海:同濟(jì)大學(xué)出版社,2009.[4]徐培福,肖從真,王翠坤. 架空連廊的震害及設(shè)計(jì)建議[J].建筑結(jié)構(gòu),2004, 34 (1):51-52.[5]徐培福,傅學(xué)怡,王翠坤,等. 復(fù)雜高層建筑結(jié)構(gòu)設(shè)計(jì)[M].北京:中國建筑工業(yè)出版社,2005.[6]朱鳴,張志強(qiáng),柯長華,等. 大跨度鋼結(jié)構(gòu)樓蓋豎向振動(dòng)舒適度的研究[J].建筑結(jié)構(gòu),2008, 38 (1):72-76.[7]JTG/T D60-01—2004公路橋梁抗風(fēng)設(shè)計(jì)規(guī)范[S].北京: 人民交通出版社,2004.
