000021809 520__ $$2eng$$aA plasticity model is presented for the non-linear ground response analysis of layered sites. The model is the one-dimensional version of that recently proposed by Tasiopoulou and Gerolymos (2016) for sand behavior, designated as TA-GER sand model. Critical state compatibility for monotonic and cyclic loading, anisotropic plastic flow rule and Bouc-Wen motivated hardening law are among the key-features of the developed 1D model, offering considerable flexibility in representing complex patterns of cyclic behavior such as stiffness decay and increase in strength due to build-up of pore-water pressure. Implemented through an explicit finite–difference algorithm into an in-house computer code which performs integration of the wave equations to obtain the nonlinear response of layered soil deposits, the model is first calibrated to match published experimental shear modulus and damping curves and is then validated against results from two wave-propagation codes available in literature.
