Seismic behavior of composite concrete floor without earthquake design provisions Part 1 : experimental program

Abstract : In some existing nuclear facilities in France, composite concrete floors were designed to support only gravity loads. Therefore those slabs were constructed without earthquake design provisions. In order to assess the structural dynamic behaviour and seismic margins of such slabs with regards to the resistance calculated with construction codes used in France for existing buildings, CEA and IRSN launched in 2008 a research program which is divided in two parts (1) an experimental program performed on two full scale identical models one subjected to a mono-axial in-plane static cyclic loading up to failure tested at GINGER CEBTP and one subjected to a series of bi-axial horizontal seismic excitation at CEA/Saclay on AZALEE shaking table, (2) a numerical analysis program of the tests results using the finite element code CAST3M developed at CEA/Saclay. This paper is dedicated to the presentation of the two experimental campaignsPresentation of the models (geometry, reinforcement detailing, construction, material properties),Instrumentation of the two models, Experimental campaign protocol,Main tests results. Numerical analyses performed after the experimental campaigns are presented in a second paper in this conference.
