摘要
采用双过滤白噪声模拟地震动,采用虚拟激励法,对装有MR阻尼器的智能隔震结构进行随机响应分析.算例表明,与被动隔震结构相比,在几乎相同的失效概率条件下,智能隔震结构的隔震层位移明显减小,显示了智能隔震结构的优势.
With double--filter white-noise simulating seismic motion,the random response of MR smart isolated structure is solved by pseudo-excitation method.The result shows that isolator draft of smart isolated structure is obvionsly smaller than that of isolated structure,while corresponding story acceleration of super structure just increases little.
