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.

Keywords:frame-corewall structure; super high-rise building; elastic response spectrum under fortification earthquake; elastic-plastic  dynamic time-history analysis
