本文从随机过程的理论出发,导出了结构在平稳反应下不同阻尼的加速度反应谱和标准加速度反应谱的转换公式;发现Мецкецев公式是在平稳白噪声作用下结构反应的阻尼变换公式。用不同文[7]的方法从等效平稳化的假定出发,导出了结构在非平稳反应下不同阻尼的加速度反应谱和标准加速度反应谱的转换公式。
Based on the theory of stochastic process, this paper derives the conversion formula of the acceleration response spectrum and the standard acceleration response spectrum with different damping under the smooth response. It is found that the Мецкецев formula is the damping transformation formula of the structural response under the smooth white noise. Using the method of different paper [7], based on the assumption of equivalent stationary, the conversion formulas of different damping acceleration response spectra and standard acceleration response spectra under non-stationary response are derived.
