In a seismic hazard assessment of an embankment dam, the ground motion intensity measure (IM) deemed important to the dam must first be identified (e.g., spectral acceleration, SA; peak ground velocity, PGV; and Arias intensity, AI). It is important for the IM to relate well to the engineering demand parameter (EDP) of interest. Results from a study are presented that had set out to identify IMs that related to embankment dam deformation. Read more
