A macro-element for a shallow foundation to simulate Soil–Structure Interaction considering uplift

Abstract In earthquake engineering, several approaches exist to take into account Soil–Structure Interaction (SSI): the following work is based on the “macro-element” concept. The particularity of the macro-element lies in the fact that the movement of a foundation is entirely described by a system of generalised variables (forces and displacements) defined at the foundation centre. The non-linear behaviour of the soil is reproduced using the classical theory of plasticity. This Note improves an already existing macro-element by adding the uplift behaviour of the foundation according to the plasticity theory. Comparisons with experimental results of a foundation submitted to cyclic loadings show the performance of the approach. To cite this article: S. Grange et al., C. R. Mecanique 336 (2008).
