| 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－扭转偶联地震响应，在隔震和非隔振情况下，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，采用基础隔震技术可明显减少结构的扭转响应和层间变形。

| Abstract: | 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. |
