The expressions are empirically determined based on extensive numerical simulations, which are carried out for linear SDOF(Single Degree of Freedom) systems subjected to white noise excitations. A new parameter representing a “strength of non-stationarity” of the responses is proposed for organizing the characteristics of extreme responses. The expressions for the peak factor and the cov (coefficient of variation) of extreme values are empirically determined as a function of the proposed parameter. The response spectra subjected to filtered white noise excitations are evaluated for verifying the accuracy of the expression of the peak factor. The comparisons with MCS (Monte Carlo Simulation) show that the expression is not only simple but also accurate for non-stationary responses.
