A nonlinear damping random vibration problem was solved by means of nonlinear spectral analysis. The response spectrum for the nonlinear random vibration was obtained by introducing Hermite polynomial. The study indicates that it is possible to gain high efficiency as compared with statistic linearization method. Therefore,this will provide a useful tool for solving nonlinear damping random vibration problems.
