高层住宅钢结构体系的地震响应分析

Analysis of Earthquake Response of High-rise Residential Steel Structure Systems

结合不同钢结构体系的特点,分别建立了钢框架、钢框架-偏心支撑、钢框架-中心支撑、钢框架-剪力墙有限元模型,并对其在多遇地震下进行了时程分析,通过位移、加速度的时程曲线得到不同结构体系在地震时的动力响应,通过抗侧移能力的大小来表现出这四种结构体系的差别,通过不同结构的比较得出了四种钢结构体系下的抗震性能。

Combining different steel system features ,the finite element model of steel frame ,steel frame-ec-centrically support ,steel frames-support and steel frame-shear wall were established .The four different steel structural seismic performances were obtained by used the method of time history analysis to obtain the dy-namic response through displacement and acceleration time curve ,under the multi earthquake ,reflected the difference of the four kinds structural by the anti-lateral displacement capacity .
