［摘要］针对某典型框架-核心筒结构超高层建筑，分别按小震弹性计算和弹性时程分析、中震弹性计算、大震弹塑性动力时程分析对结构抗震性能进行分析，重点对中震作用下弹性计算和弹塑性动力时程计算进行对比分析，分析了中震作用下框架和核心筒基于弹性反应谱与弹塑性计算的内力和配筋变化规律。结果表明，对框架-核心筒结构超高层建筑采取相应计算方法和加强措施，并对中震弹性计算配筋进行适当调整后，结构可满足中震抗震性能目标。

Abstract:For a typical super high-rise building with frame-corewall structure, the seismic performance of the structure was analyzed using elastic calculation and elastic time-history analysis under  frequent earthquake, elastic calculation under fortification earthquake and elastic-plastic dynamic time-history analysis under rare earthquake, focusing on the comparison and analysis of elastic calculation and elastic-plastic dynamic time-history calculation under fortification earthquake. The variation of internal force and reinforcement of frame and corewall under fortification earthquake was analyzed based on elastic response spectrum and elastic-plastic calculation. The results show that the structure can meet the seismic performance target under fortification earthquake after adopting the corresponding calculation method and strengthening measures for the super high-rise building with frame-corewall structure, and adjusting the elastic calculation reinforcement appropriately under fortification earthquake.
