The objective of this research focus is to develop digital tools for understanding and accounting for Soil-Structure Interaction in order to assess the vulnerability of structures subjected to static (monotonic/cyclic) or seismic loads.
The focus will be on developing both refined modeling strategies (coupled hydro-mechanical calculations, microstructured media) and simplified approaches (suitable for use in engineering firms) for the nonlinear behavior of the structure, its support (foundation), and the soil.

RESEARCH EXAMPLES
FACILITIES
Experimental methods and adapted optical techniques are developed for laboratory monitoring of the aforementioned processes. It is worth noting that some of these research subjects have no equivalent worldwide.
Mechanical modeling is developed while always positioning itself at the interface between macroscopic modeling of continuous media, whether enriched and/or micro-morphological, and homogenization modeling, in order to address any issues related to the multi-physics and multi-scale nature of the phenomena considered.
Numerical simulation is integrated with mechanical modeling through the development of suitable finite elements, but it will also operate independently within the framework of discrete element methods (DEM), Smoothed Particle Hydrodynamics (SPH), and Machine Learning.
