Stage PFE - Interaction Sol-Structure dynamique avec pieux
Core
Develop a parametric 3D model and automated workflow to calculate soil-structure interaction impedances for pile foundations in seismic safety assessments.
Role type
Junior IC geotechnical/structural dynamics engineer (intern)
Builds
Parametric 3D models (Code_Aster, Salome_Meca) and automated Python scripts for pile group impedance calculations
Domain
Geotechnical engineering + Structural dynamics
Required skills
Finite element analysis (FEM), Python scripting, modal analysis, soil-structure interaction modeling, sensitivity analysis
Preferred skills
Geotechnical mechanics, non-linear soil modeling, FEM/BEM coupling
Technologies
Code_Aster, Salome_Meca, Python, ANSYS, MISS3D
Responsibilities
Review literature on dynamic pile modeling and group effects; benchmark simplified vs. 3D linear/non-linear models; develop automated 3D impedance calculation tools; derive equivalent spring-damper systems from impedance matrices; perform sensitivity studies on soil parameters and boundary conditions; validate and document the method.
Seniority
Junior, hands-on IC
