Seismic Evaluation of Existing Nuclear Facility Using Non LinearModelling

摘要

This paper aims at presenting the methodology and the non-linear modelling used for the seismic evaluationof existing nuclear facilities. Two different calculation methods are applied to the seismic analysis of a 4 storeyreinforced concrete frame tested with the pseudynamic method. In a first step, static and dynamic analysis areconducted with non linear beam elements. The second part shows the application of the simplified hinge methodbased on a event-to-event dynamic calculation. The main problems to be solved during the seismic assessment ofexisting facilities regarding the utilization of non linear modeling such as the definition of damage index accordingsafety requirements are discussed in this paper.
