Finite element modelling of flexural behaviour of externally bonded CFRP reinforced concrete structures

This paper focuses on the flexural behaviour of RC beams externally reinforced using Carbon Fibre Reinforced Plastics (CFRP) plates. A non-linear finite element (FE) analysis is proposed in order to complete the experimental analysis of the flexural behaviour of the beams. An elasto-plastic behaviour is assumed for reinforced concrete and interface elements are used to model the steel-concrete bond and the adhesive. The numerical analysis also includes simulations on pre-cracked beams.
