Frame-core-outriggers structural system was adopted in the structure. The frame was composed of steel reinforced concrete composite columns and steel beams, the core was made of reinforced concrete shear walls, and the peripheral frame and inner core were connected with outriggers and belt trusses. The foundation includes 1m diameter, 61m long cast-in-site piles with post grouting technology and mat of 4.3m thickness in this project. Structural performance index, structural calculating result, vertical deformation difference analysis and disposal measures, outriggers and belt trusses design, and elasto-plastic analysis were introduced.Keywords: frame-core-outriggers structural system; performance index; strengthened stories design; elasto-plastic analysis作者簡介:劉晴云,教授級高級工程師,Email:qingyun_liu@ecadi.com。參考文獻(xiàn)[1] 華東建筑設(shè)計研究院有限公司.上海北外灘白玉蘭廣場辦公塔樓超限高層抗震審查報告[R].2011.[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] 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[M]. 北京:中國建筑工業(yè)出版社,2005.[4] 周建龍,閆鋒.超高層結(jié)構(gòu)豎向變形及差異問題分析與處理[J].建筑結(jié)構(gòu),2007,37(5):10-13.[5] J 10285—2003 高層建筑鋼-混凝土混合結(jié)構(gòu)設(shè)計規(guī)程[S]. 上海:上海市建設(shè)工程標(biāo)準(zhǔn)定額管理總站,2003.
