Within this context, a beam on nonlinear Winkler foundation model is adopted based on the Boundary Element Method (BEM), accounting for the effects induced by geometrical nonlinearity, rotary inertia and shear deformation, employing the concept of shear deformation coefficients. The soil nonlinearity is taken into consideration by means of a hybrid spring configuration consisting of a nonlinear (p-y) spring connected in series to an elastic spring–damper model. The nonlinear spring captures the near–field plastification of the soil while the spring–damper system represents the far–field viscoelastic character of the soil. An extensive case study is carried out on a pile–column–deck system of a bridge, founded in two cohesive layers of sharply different stiffness and subjected in various earthquake excitations.
