Abstract
Site-dependent response spectra accounting for soil nonlinearity are at Grst estimated and then simulated accelerograms compatible with prescribed response spectra are generated. Inelastic response analysis for different idealized structural systems subjected to simulated accelerograms is performed, focusing on the effect of local soil conditions and input motion intensity on normalized drift response. Results presented in this study indicate that for relatively long period structural systems increasing softness of soil deposit is associated with increasing spectral response. This general tendency becomes less visible for relatively low level of yield acceleration and high level of input motion intensity.
