[摘要]以實(shí)際工程為背景,采用簡(jiǎn)化模型,對(duì)帶加強(qiáng)層結(jié)構(gòu)體系、密柱深梁結(jié)構(gòu)體系、外桁架筒結(jié)構(gòu)體系這三種在超高層建筑中常用的結(jié)構(gòu)體系進(jìn)行分析。采用ETABS,MIDAS Building軟件,通過(guò)彈性、靜力彈塑性及動(dòng)力彈塑性時(shí)程等分析方法,比較上述三種結(jié)構(gòu)體系在高烈度區(qū)的結(jié)構(gòu)性能,從而分析得出每種結(jié)構(gòu)體系的整體受力、變形特點(diǎn)。

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
