摘要

为了研究框架-剪力墙基础隔震结构的地震扭转反应,建立了地震作用下高层框架剪力墙基础隔震结构的平移-扭转耦联振动模型和运动方程,分析了单轴偏心基础隔震结构的平移-扭转耦联地震响应,并探讨了不同偏心率下隔震结构的地震反应.结果表明:在结构设计中应合理调整隔震结构上部结构和隔震层的偏心率.只有在上部结构和隔震层的偏心率满足一定关系的情况下,采用基础隔震才能明显减小结构的扭转反应.
In order to investigate the seismic torsional response of base-isolated structures with frame-shear walls,the lateral-torsion coupling vibration model and the corresponding motion equation are formulated for the high-storey structure with frame-shear wall and isolated foundation under seismic action.The lateral-torsion coupling seismic response of the uniaxialeccentricity base-isolated structure is then analyzed,and the seismic responses of several base-isolated structures with various eccentricity ratios are discussed.The results show that the eccentricity ratio of the superstructure to the base-isolated layer should be reasonably adjusted in the design of a structure,and that the torsional response of the base-isolated structure can be obviously reduced only when the eccentricity ratio satisfies a certain condition.
