［提要］  结合中国平安金融大厦超限高层的结构设计，详细介绍了基础与上部结构设计及节点设计构造，特别是针对这种外周圈为SRC框架结构，中央为钢管混凝土(CFT)柱、钢梁以及钢支撑构成的框架支撑结构体系。采用ETABS有限元程序对结构在多遇地震作用下结构构件的强度、刚度、整体稳定性进行分析，并选用上海市《建筑抗震设计规程》(DJ08—9—2003)所列的4条上海人工地震波对整体结构进行了弹性动力时程分析补充计算，对整体结构采用罕遇地震作用下静力弹塑性Pushover分析。结果表明，该结构体系是安全、可行的。

Abstract:Referring to design of super highrise building of Pingan Finance Tower,the design of foundation,superstructure and joint construction,especially this frameshoring system consisting of SRC frame structure in the periphery and concrete filled steel tubular (CFT) column,steel beam and steel support in the middle are introduced.Based on the ETABS procedure,the strength,rigidity and integral stability of the structural member under the action of frequently occurred earthquake are analyzed;elastodynamic timeprocedure analysis on integral structure are carried out in adoption of Shanghai artificial seismic wave listed in 4 items of Code for Seismic Design of Building(DJ08—9—2003),and pushover analysis on overall structure under the action of rare occurrence earthquake is finished.The results show that this structure is safe and reliable.
Keywords:CFT concrete filled steel tubular column; steel brace; nonlinear static pushover analysis; sliding support
