520			_aA simplified numerical methodology is presented in the present study to investigate the seismic response of single piles in liquefiable multi-layered sloping ground taking into account of both kinematic and inertial interaction effects using pseudo-static approach based on beam on nonlinear Winkler foundation (BNWF) model. The open-source finite element-based code, OpenSees, is used to conduct the analysis using results obtained from a separate free-field effective stress-based nonlinear ground response analysis. The present numerical model has been validated with the established theoretical solution and past case study. The parametric studies have been performed for evaluating the influence of various parameters on seismic response of layered soil–pile system. The results show that the peak lateral displacement and bending moment of piles are significantly influenced by ground slope, slenderness ratio of pile, pile head fixity condition, depth of liquefiable layer and pile embedment depth. The peak bending moment occurs near the interface between liquefiable and non-liquefiable layer when the depth of liquefiable layer is almost 22% and embedment depth is almost 45% of total length of pile. It is also observed that peak lateral displacement of pile reduces and peak kinematic pile bending increases in liquefiable sloping ground with increasing of embedment depth of pile.
