The knowledge of this degradation process can be used with efficiency in order to assess the time history response and the aseismic design of critical structures such as dams, nuclear power plants and other important facilities. The objective of this study is to identify the effects of the frequency nonstationarity, on the nonlinear structural response, by using a nonstationary stochastic model based on the concept of physical spectrum and simple inelastic structural models.The nonstationary stochastic model is used to simulate, two sets of artificial earthquakes compatible with a real ground acceleration record and exhibiting similar phases distribution [6] and different frequency contents. The first group presents a time varying frequency content and the second one group has a time invariant frequency content. Three hysteretic models have been considered. The variability of the maximum displacement ductility was represented in terms of probabilistic inelastic response spectra for the two groups of the precedent simulated accelerograms.
