Modeling surface waves.
Designing safer structures.
IM-SURF studies the impact and mitigation of seismic surface waves (Rayleigh, Love) on large 3D structures — moving engineering practice beyond the conventional 1D approximation toward full 3D dynamic soil-structure interaction analysis, and toward practical guidelines for when that matters.
About IMSURF
IM-SURF is a research project funded by the French National Research Agency (ANR). It studies the impact and mitigation of seismic surface waves on large 3D structures, building on the earlier ANR MODULATE project.

Program
The proposed project is divided into 5 Work Packages (WP). Each WP contains tasks with detailed actions, milestones and deliverables.
Each WP has a partner as responsible Leader, who coordinates the tasks of the WP.
Working Packages
- WP1 - Project Management and Dissemination of results
- WP2 - Enrichment of existing strong motion databases for surface wave studies
- WP3 - Numerical techniques for obtaining full 3D wave regimes from the geological to the geotechnical scale
- WP4 - Development of numerical techniques for seismic SSI calculations with complete wave regime and presence of strong nonlinearities in the near field
- WP5 - Seismic performance of structures of large dimensions subjected to the incidence of “3D” motions with surface waves
The following figure presents the global flowchart of IM-SURF project with the role of each partner of the research consortium.
