In this paper, a two-dimensional non-linear finite element model is proposed for seismic analysis of integral abutment bridges (IABs). The model captures the soil-pile-structure interaction and includes far-field soil inertia effects and piles non-linear behavior. The compression-only (gap) elements behind abutments were used to detect possible soil wall separation phases during earthquakes. The gap stiffness parameter was studied, and a recommendation is given for its value. To validate the proposed model, several ground motion time histories were applied to pile supported single cantilever walls with free-field soil and gap elements. The active/passive seismic earth pressures exerted on the wall were compared with the conventional Mononobe-Okabe method, which is often used by practicing engineers. The results indicate that the proposed FE model is appropriate for seismic analysis of IABs and captures the soil-pile-structure interaction effects with acceptable accuracy in all phases of ground motions.
