SSI效应对隔震结构地震响应的影响分析
Effects of Soil-Structure Interaction on Earthquake Response of Isolated Structure System
摘要
Abstract
Through analyzing the data of shaking table model tests of isolated structure on fixed ground base and soil ground base, the effects patterns of soil-structure interaction (SSI) on dynamic characteristic and earthquake response of isolated structure are studied. The results show that effects of SSI on foundation motion of isolated structure are great, the peak value of foundation motion is smaller than that of the free field, and the spectral component of foundation motion is different. Effects of SSI on acceleration amplification factors of floors of isolated structure are significant, and the acceleration amplification factors of floors is greater than those on fixed ground base. One of main factors leading to the acceleration response of floors increasing is swing motion caused by rotation of isolated layer, which is the constitutions of acceleration amplification factors of floors.关键词
