摘　　要：针对超高层混凝土框架-核心筒结构的弹塑性时程分析与性能化设计进行了研究。首先,对Midas Building的有限元理论进行介绍。在此基础上,对某超高层框架-核心筒进行弹塑性分析,并对结构进行性能化分析与研究。结果表明,在罕遇地震作用下,结构楼层位移角时程包络满足不大于1/100抗震设防要求;实现了“强柱弱梁”的延性设计要求,整个外框架梁在罕遇地震作用下基本保持弹性工作状态,框架柱应变始终未超出屈服应变值,该结构设计分析研究对此类超高层框架-核心筒结构设计提供参考。The elastic-plastic time history analysis and performance design of super high-rise concrete frame-core tube structure are studied. The finite element theory of Midas Building are introduced. On this basis, the elastic-plastic analysis as well as performance analysis of a super high-rise frame-core tube are carried out. The results show that the time history envelope of the displacement angle of the structural floor meets the seismic fortification requirements of not more than 1/100 under the rare earthquake;the ductility design requirements of the "strong column weak beam" are realized, and the entire outer frame beam is in the rare earthquake The basic elastic state is maintained, while the strain of frame columns never exceeds the yield strain value. The reference for the design of such super high-rise frame-core tube structures is provided by the research of structural design analysis provides.
