Probabilistic evaluation of seismic response of fluid-structure system

Technical Report:

Abstract

Given the seismic characteristics of Italian territory, structural safety problems as a consequence of possible earthquakes are of upmost importance for ENEL (Italian Board of Electricity) which directly manages most of the largest electric power plants in Italy. Recently, ENEL recognized the opportunity to develop a probabilistic approach to the safety evaluation of the most important dam-reservoir systems and, to this purpose, a research program in cooperation with the CISE research institute and with the Department of Structural Mechanics of the University of Pavia was defined. As a first step, a method for the analysis of a deterministic linear system, whose response randomness is due to the seismic input only, was set up; a finite elements model of the dam-reservoir system was employed in the probabilistic approach. The comparison of a real system response to different space distributions of the seismic input (uniform and multisupport excitation) is reported.
