摘　　要：采用微分型滞回恢复力模型模拟隔震支座的恢复力特性,对基础隔震单层偏心结构的扭转地震反应进行分析,研究隔震系统偏心距和上部结构偏心距对结构扭转反应的影响。结果表明,采用隔震技术可以显著降低隔震结构的扭转地震反应。In this paper, the differential hysteretic restoring force model is used to simulating the characteristic of restoring force of isolation bearings. The torsional seismic response of one-story asymmetric structure is calculated, the influences of eccentricity of the isolation system and the supper-structure on torsional response of the structure are investigated. It is proved that the torsional response of the structure could be greatly reduced by means of base isolation techniques.
