Strong ground motion and site effects

Strong ground motion and site effects

The Research Unit of SDGEE is a world leader in experimental and numerical studies of strong ground motion and site effects. Among its diversified activities, it operates since 1995, with the collaboration of several European institutes and ITSAK, a unique experimental site (EUROSEISTEST) dedicated to the in-depth study of site-effects and strong ground motion. In particular, we perform:

  • ID empirical site response characterization (HVSR, SSR, GIS methods)
  • ID, 2D and 3D numerical modeling of site response
  • 2D/1D aggravation factor
