Elastoplastic analysis of the soil-foundations-structure interaction

Résumé

This paper presents analysis of the influence of the presence of a structure on the soil-foundation-structure interaction. Analysis is carried out using a global elastoplastic finite element modelling of the soil-foundation-structure system. It is based on comparing the response of a single foundation to that of both adjacent foundations and soil-foundation-structure system. Analyses show that the interaction between adjacent foundations does not affect their response to vertical load, while the presence of the structure could affect largely the response of the soil-foundation-structure to vertical loads, in particular for high values of the soil-structure relative stiffness. The presence of the structure induces additional loads to the foundation (lateral reaction and overturning moment), which result in a reduction of the vertical bearing capacity of the foundation. These analyses show the necessity to consider the soil-foundation-structure in foundations design.
