Numerical Modeling of Reinforced Concrete Beams Strengthened by NSM-CFRP Technique
Résumé
The NSM method has been used in recent years for the strengthening of RC beams with CFRP materials. A numerical study has been carried out on rectangular RC beams, strengthened with NSM-CFRP by using FE code ATENA. The numerical FE simulations were compared with experimental measurement tested by other investigators on specimen strengthened with NSM CFRP strips. On overall, the predicted FE peak loads and mid-span deflection responses agreed quite well with the corresponding measured experimental tested data at all stages of flexural loading. Therefore, the developed FE model is suitable as a practical and economical tool especially in parametric studies for accurate modeling and analysis of flexural strengthening of RC members with NSM-FRP reinforcement.
