Etude expérimentale et modélisation du comportement en flexion de poutres BA renforcées par collage de composites
This paper focuses on the flexural behaviour of RC beams strengthened using carbon fibre pultruded plates. Several parameters (number of layers, effect of a pre-cracking) are investigated in a first experimental part on full-scale beams. Then a non linear finite element (FE) analysis is proposed in order to complete the analysis of the behaviour of the strengthened beams. An elastoplastic behaviour with hardening is assumed for reinforced concrete and interface elements are used to model the steel-concrete bond and the adhesive. They enable to study the normal and shear stress distribution in the adhesive. This numerical analysis also includes simulations on pre-cracked beams.
