Three Dimensional Probabilistic Soil-Structure-Interaction Analyses for Buildings of NPP Beznau
Year: 2007
Type: conference-paper
Abstract: In the framework of new evaluation of fragilities for the seismic probabilistic safety analysis of the Beznau NPP, threedimensional probabilistic seismic response analyses including the soil-structure interaction effects are performed for ten safety-related buildings using computer code SASSI2000.The generation of Acceleration Response Spectra (ARS) for seismic design and re-qualification of safety-related components is based on deterministic analyses according to the stateof-the-art methods in the mid eighties using simple lumped-mass stick models of structures with frequency-independent soil springs and dampers.This paper presents the assumptions for the probabilistic response analyses and comparisons of ARS from the probabilistic analyses and the earlier deterministic design analyses.The results of the probabilistic SSIanalyses are basis to evaluate seismic fragilities for structures and components.1
