摘要
对由高效阻尼装置(HEDMS)连接的两单自由度相邻结构在过滤白噪声激励下的相对位移响应进行了随机分析。在对阻尼装置滞变位移等价线性化的基础上,采用虚拟激励法计算结构响应的谱密度和互谱密度,研究了该阻尼装置各参数对位移响应方差的影响以及该装置的适用范围。
Stochastic dynamic Analysis of two single degree of freedom adjacent buildings linked with HEDMS (High Efficient Damper Suitable for Multi-Structure System) under earthquake excitation is presented here. The ground motion is idealized as filtered white noise process. On the basis of linearization of damper's hysteresis displacement, Pseudo-excitation algorithm is adopted to compute spectral density. according the deviation of displacement, some studies on parameters of the HEDMS are performed in this paper.
