The project selects reinforced concrete tube in tube structural system, the frame column is steel tube confined concrete column and it uses the partial reinforced concrete frame-wall outriggers. Through-calculation and analysis, the structural design is verified to be safe and reasonable, and the results indicate that the structural design can satisfy the seismic performance requirements.Keywords:reinforced concrete tube in tube structural system;steel tube confined concrete column;partial reinforced concrete frame-wall outriggers作者簡介:唐蘭云,高級工程師,一級注冊結(jié)構(gòu)工程師,Email:cloud881@sina.com。參考文獻[1]JGJ94—2008建筑樁基技術(shù)規(guī)范 [S]. 北京:中國建筑工業(yè)出版社,2008.[2]GB50011—2001建筑抗震設(shè)計規(guī)范[S]. 2008年版.北京:中國建筑工業(yè)出版社,2008.[3]劉大海,楊翠如.高樓結(jié)構(gòu)方案優(yōu)選[M]. 西安:陜西科學(xué)技術(shù)出版社,1992.[4]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.[5]趙西安.高層結(jié)構(gòu)設(shè)計[M]. 北京:中國建筑工業(yè)出版社,1995.[6]徐培福.復(fù)雜高層建筑結(jié)構(gòu)設(shè)計[M]. 北京:中國建筑工業(yè)出版社,2005.
