heal.abstract	A number of analysis methods of varying degrees of accuracy and efficiency have been developed in the past decades for the response of dams, earth embankments treated as one dimensional shear wave propagation problem. However, ""shearwedge"" model involve complicated material and geometric nonlinearities, such as soil inelasticity, stiffness and strength degradation with cycling loading and radiation damping. In this work, the nonlinear response of shear-wedges is described through a hysteretic model of Bouc-Wen type that can handle all types of hysteretic behaviour from a phenomenological perspective. This study preliminary addresses (a) the lateral monotonic, (b) the dynamic - sinusoidal type - response of wedges and (c) dynamic response to Ricker and Tsang pulses. Numerical examples are presented that illustrate the non-linear behaviour and versatility of the unified approach. © 2006 Civil-Comp Press.	en
