基于小波包变换的摩擦滑移隔震结构能量分析
Analysis of sliding-isolated structure energy based on wavelet packet transform
【摘要】 采用小波包变换的方法,分析了摩擦滑移隔震结构在不同场地类别地震波重构信号作用下能量传递规律.结果表明,地震波的低频信号对结构能量反应起主要作用;对于不同的场地类别,摩擦系数对隔震结构能量传递的影响不同.
【Abstract】 Based on the wavelet packet transform,the law of energy response of sliding-isolated structure under deferent site reconstructed seismic wave is analyzed.The results show that the low-frequency signals of seismic wave play a major role in the energy reaction of the sliding-isolated structure;As far as the venues is concerned,the influence of friction coefficient to the energy transfer is different.
