employing an appropriate numerical model is the most practical method to evaluate site effects on propagated ground motion , this paper employs one -dimensional numerical site response analysis models to investigate seismic response of stiff granular soil deposits on vertical propagation of horizontal shear waves. soil response is modelled by traditional equivalent -linear EL frequency -domain analysis using DEEPSOIL software and nonlinear NLtime domain analysis using OPENSEES software.
