Abstract

The work is concerned with the development of an original macro-element model for shallow foundations within the context of performance-based design of structures. The macroelement can be viewed as a link element placed at the base of the structure that reproduces in a simplified, yet coherent way the non-linear interaction phenomena arising at the soil-footing interface during dynamic excitation. As such, it offers an efficient prediction of the maximum and permanent displacements at the foundation level by identifying the non-linear mechanisms that produce them. These are: (a) the sliding mechanism along the soil-footing interface, (b) the irreversible soil behaviour mechanism and (c) the foundation uplift mechanism. These non-linear mechanisms are introduced within the macro-element model in a fully coupled way. In its present state of development the model can be used for strip and circular footings in purely cohesive or purely frictional soils.
