| 摘 要： | 首先推导出层间隔震结构的结构动力模型,采用将地震学中低频模拟方法和工程学中高频模拟方法相结合的综合功率谱模型,来模拟地震地面运动功率谱。其次用虚拟激励法进行层间隔震结构的随机响应分析。文末对一个20层的层间隔震框架作数值模拟,探讨了隔震层设置在不同层时,对结构层间位移随机响应的影响,通过各种综合因素的比较,而获得隔震层设置的最佳位置。

| Abstract: | This article firstly deduces the dynamic model of interlayer seismic isolation,adopts the comprehensive power spectrum model which combines the low frequency simulation method in seismology and the high frequency simulation method in engineering,to simulate the power spectrum of earthquake ground motion.Secondly pseudo excitation approach is employed to analyse random response.Finally,a 20-story interlayer seismic isolation frame is used as numerical example;the effect of Random response in interstory drift is discussed when isolation floor lies different floor.Comparing each kind of comprehensive factor,We can obtain the best position of isolation floor. |

| Keywords: | interlayer seismic isolation pseudo excitation approach random vibration isolation floor |
