Abstract: In the nuclear industry, the seismic probabilistic risk assessment (PRA) has become the most commonly used methodology for evaluating the seismic risk of nuclear plants. In this framework, fragility curves express the conditional probability of failure of a structure or component for a given seismic input motion parameter value. The failure probability of a component due to a seismic event is obtained by integrating the conditional probability of failure (fragility) with respect to seismic hazard curve. In this paper, we present an application of moment independent sensitivity measures as introduced by Borgonovo in order to assess the sensitivity of these curves with respect to model parameters.
