This paper extends the mode-acceleration decomposition method to random vibration. The power spectral density function of the response of building under the excitation of earthquake has been derived based on mode-acceleration method. Then a mean-value response spectrum random mode-acceleration method has been proposed based on the spectral moment theory and extreme value theory in random vibration.Using the proposed method, the statistics of maximum responses of building under earthquake can be obtained.The calculation results of a twelve-story building show that the combination of only a few first modal responses can yield accurate results and the convergent rate of this method is far faster than the existing random mode-displacement method.This method is particularly applicable to the analysis of stochastic seismic response of high-rise buildings with non-coincident mass and elastic centres.
