Analysis of seismic risk on existing dams. Part I: an example of masonry structure

The paper deals with the analysis of a gravity masonry 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 Abaqus and the analysis suggested by the Italian code for dams was performed. Verifications in terms of stresses, in non-linear range assuming a concrete damaged plasticity model for masonry, were made, showing their compatibility with both tensile and compressive strengths
