heal.abstract	This paper studies how 1D equivalent-linear analyses may be accurately used for simulating the seismic response of sites improved with inclusions (e.g. gravel columns). For this purpose, the composite ground is modeled as an equivalent-uniform material, whose dynamic non-linear properties are a function of the respective properties of the natural soil and the inclusion material (e.g. gravel), as well as the replacement ratio of the composite ground. The equivalent-uniform model of the composite ground has a theoretical basis and is verified by comparing parametric results from pertinent 1D and 2D seismic ground response analyses, performed with the equivalent-linear method, for small and high intensity motions. Emphasis is put on replacement and solidification of cohesive soils using a grid of reinforcing columns (inclusions). © 2006 Taylor & Francis Group.	en
