摘要

为研究高层建筑采用铅芯橡胶垫进行隔震后的结构减震效果,对一两向不同高宽比1:16小比例尺隔震结构模型,进行了双向不同地震波输入下的地震反应数值计算和振动台试验分析。对模型上部结构加速度和隔震支座位移反应的分析表明,隔震技术对高层建筑同样有较好的减震效果;数值计算结果与振动台试验结果的对比分析表明,两者具有较好的一致性,数值计算较好地模拟了振动台试验;两组数据的相近证明了数值计算结果和振动台试验过程进行的正确性。
For analyzing vibration reduction effect of a high-rise isolated structure with LRB,numerical calculation and shaking table test for two-directional earthquake responses of an isolated structure model under different earthquake waves were done.The model structure had different height-width ratios in two directions with a scale of 1:16.Earthquake acceleration responses of the model structure top and the isolation bearing displacement responses were analyzed.Analysis showed that the isolation technology for high-rise structures also has good vibration reduction effect.Analysis of shaking table test results and numerical calculation results showed that the numerical calculation works well for simulating the shaking table test;the agreement between them verifies the correctness of the numerical calculation results and the shaking table test.
