The Acciano rockfill dam was originally designed withouttaking seismic action into account. The area where it is located is nowclassified in the 2nd seismic zone, according to the current Italianregulations. On September 26th 1997, an earthquake of magnitude Mw=5.5,one of the largest seismic events of the last 20 years in Italy, occurred in thatarea and caused some visible damage to the dam. Subsequent investigationprogrammes and structural assessments were carried out to evaluate theresidual safety margins of the dam in order to identify possible rehabilitationprovisions to comply with the Italian standards for seismic design. This paper describes the evaluation of the post – earthquake condition of thedam and outlines the assessments to validate the rationale of therehabilitation project.
