| 摘 要： | 选择金井清过滤白噪声模型,采用留数定理推导出K-T谱激励的自相关函数表达式,并在此基础上利用相关函数法分析出K-T谱激励下的平稳反应,并采用功率谱方法加以验证。这些结果可为结构随机地震反应时域分析和抗震可靠性评估提供基础。

| Abstract: | In this paper,Kanai-Tajimi filtered Gaussian white noise model is researched for representing the actual earthquake ground acceleration.The residue theorem is used to derive the autocorrelation function expression of Kanai-Tajimi spectrum excitation.Then the stationary response under K-T spectrum excitation is obtained using the correlation function method and confirmed by the power spectrum method.These results provide a basis for the random response analysis and reliability assessment of the earthquake resistant capacity of structures in time domain. |
