Approximate solution methods for nonlinear random vibration problems are developed using computational tools of the time-invariant structural reliability theory. The basic framework of the approach is composed of: 1) representation of the input stochastic excitation in terms of a finite number of random variables, 2) formulation of each response statistic of interest in terms of one or more limit-state functions of the random variables, and 3) estimation of the response statistic using computational reliability tools.
