【摘要】 通过振动台地震模拟试验,以砂与橡胶颗粒混合垫层为研究对象,分析二层简化模型结构在不同橡胶颗粒含量下的隔震性能,研究了橡胶粒含量对减震率的影响。结果表明:随着橡胶颗粒含量的增加,结构各层的最大加速度呈减小趋势;当橡胶颗粒体积含量小于50%时,45%的橡胶颗粒体积含量配比为最优。更多还原

【Abstract】 The compound isolation cushion with sand and rubber was studied by simulation of shaking table experiment to investigate the performance of sliding base isolation under different rubber content in the isolation cushion and the effect of rubber content in isolation cushion on vibration reduction ratio. The result showed that the maximum acceleration in each layer of the structure reduces as the content of rubber in the isolation cushion increases. When the volume content of rubber is less than 50%,the optimal proportion of rubber particles volume content is 45%.更多还原
