【摘要】 遭受地铁振动影响的建筑往往位于抗震设防区,对这类建筑进行隔振设计时,其隔振层最好兼具隔震的效果。某6层砌体结构采用了橡胶支座与叠层橡胶滑板支座并联的组合隔振(震)系统,针对这种组合隔振(震)系统的水平隔震效果进行了振动台试验研究,对比了隔震和非隔震情况下模型结构在不同水准地震作用后的动力特性、加速度反应、层间位移角反应、基底剪力及模型结构的破坏情况。结果表明,这种组合隔振(震)系统的水平隔震效果明显。更多还原

【Abstract】 Buildings suffered from the subway-induced vibration are frequently located in the seismic fortification area.The vibration isolation layer is expected to have the seismic isolation capacity when designing such buildings.A six-story masonry structure was equipped with rubber bearings and laminated rubber sliding bearings.To appraise the horizontal seismic isolation effect of the composite isolation system,the dynamic characteristics,acceleration responses,relative storey drifts,base shear force and damage of the structure with and without the composite isolation system under different earthquake levels were tested on the shaking table.The results show that the horizontal seismic isolation effect of the composite isolation system is remarkable.更多还原
