A recent research on seismic assessment of concrete dams is illustrated in this chapter, including a brief comparison with other available approaches to the subject. The work of the authors has been focused on development and validation of a probabilistic methodology taking into account the uncertainties affecting structural data and external actions as well as the physical complexity of the dam-foundationreservoir system. The seismic response of such a system is estimated from a reduced number of dynamic finite element analyses and the corresponding fragility curves are obtained via a Monte Carlo simulation procedure. The main results of the application of the proposed methodology to the case of an existing concrete gravity dam are finally summarized.

Abstract
A recent research on seismic assessment of concrete dams is illustrated in this chapter, including a brief comparison with other available approaches to the subject. The work of the authors has been focused on development and validation of a probabilistic methodology taking into account the uncertainties affecting structural data and external actions as well as the physical complexity of the dam-foundationreservoir system. The seismic response of such a system is estimated from a reduced number of dynamic finite element analyses and the corresponding fragility curves are obtained via a Monte Carlo simulation procedure. The main results of the application of the proposed methodology to the case of an existing concrete gravity dam are finally summarized.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
