[摘要]以实际工程为背景,采用简化模型,对带加强层结构体系、密柱深梁结构体系、外桁架筒结构体系这三种在超高层建筑中常用的结构体系进行分析。采用ETABS,MIDAS Building软件,通过弹性、静力弹塑性及动力弹塑性时程等分析方法,比较上述三种结构体系在高烈度区的结构性能,从而分析得出每种结构体系的整体受力、变形特点。

Abstract: Based on a practical building, three typical super high-rise structural systems were analyzed, including frame-core wall structural system with outriggers and belt members, dense columns and deep beams structural system and braced frame-core wall structural system. Through the methods of elastic analysis, Pushover analysis and dynamic elastic-plastic time-history analysis, programs of ETABS and MIDAS Building were applied to compare the structural performances of three structural systems in the high seismic fortification intensity region, and the structural mechanism and deformation performance were given.
Keywords: super high-rise building; high seismic fortification intensity region; with outrigger and belt member; dense column and deep beam; braced frame-core wall structure
