［摘要］武漢中心塔樓為巨柱框架-核心筒-伸臂桁架體系的超高層結(jié)構(gòu)，框架柱采用了大直徑鋼管混凝土柱，底部核心筒為內(nèi)置鋼板組合剪力墻。對(duì)該工程結(jié)構(gòu)的特點(diǎn)進(jìn)行了闡述，介紹了其抗震超限設(shè)計(jì)的主要措施；對(duì)大直徑鋼管柱及梁柱節(jié)點(diǎn)、伸臂桁架伸入核心筒節(jié)點(diǎn)等關(guān)鍵部位的做法進(jìn)行了探索；最后對(duì)利用施工順序優(yōu)化主動(dòng)控制結(jié)構(gòu)內(nèi)力分布的設(shè)計(jì)方法進(jìn)行了嘗試。

［關(guān)鍵詞］鋼管混凝土柱；伸臂桁架；鋼板組合剪力墻；結(jié)構(gòu)內(nèi)力；主動(dòng)控制

Abstract: Tube-frame structural system with outriggers is adopted in super high-rise building Wuhan Center Tower. Huge size concrete filled steel tubes（CFT）act as columns and steel-concrete composite shear walls are used at the bottom part of the tube structure. Structural characteristics of the project were expatiated, and seismic measures for this structure that is beyond the scope of Chinese code were introduced. Details of the huge size CFT column and the column-beam joint, as well as different approaches of outrigger-tube connection were explored. Method of adjusting force distribution by optimizing the construction process with active control technology was attempted.

Keywords:  concrete filled steel tube; outrigger; steel-concrete composite shear wall; structural force；active control
