摘　　要：建立了地震作用下多层框架隔震结构的平移 扭转耦联振动模型和相应的运动方程 ,分析了基础隔震下双轴偏心框架结构平移 扭转耦联地震响应 .在隔震和非隔震情况下 ,计算了多层框架结构不同偏心的地震反应 .结果表明 ,对易于扭转变形的结构 。The translation-torsion coupling model and motion equation of isolated multi-story frame structure under earthquake action are established. The translation-torsion coupling seismic responses for a double-axis eccentric frame building with base isolator are analyzed. The seismic responses of multi-story frame structure under different eccentricities with or without base isolator are calculated. The results indicate that the base-isolation can decrease the torsional responses and interstory deformations of the multi-story frame structure significantly.
