A simplified, efficient and cost-effective numerical procedure to perform the phenomenological elasto-plastic seismic response analysis of earth dams is developed. The procedure is applicable to long dams with nearly symmetrical triangular cross-sections made of homogeneous horizontal layers and accounts for the presence of water in the dam material. The method is based on a two-dimensional Galerkin formulation of the equations of motion for the dam material, and fully coupled soil skeleton and pore water equations are used in the saturated portion of the dam. The soil skeleton nonlinear hysteretic response is modelled using an effective stress multi-surface elasto-plastic constitutive model.
