Analysis of seismic risk on existing dams. Part II: an example of concrete structure

The paper deals with the analysis of a light-weight gravity concrete dam in Italy. Its mechanical properties are defined by means of experimental tests on the dam and the bedrock. A 3D finite element model was implemented in Strand 7 r.3.4 and the procedure described by the Italian code for dams was performed. Verification in terms of stresses, in non-linear range were made, to assess the structural safety and vulnerability to piping effects
