The results of an experimental and analytical Study of the behaviour of reinforced concrete (RC) T-section beams strengthened with carbon fibre reinforced polymer (CFRP) sheets are presented. Shear deficient specimens are strengthened by using side-bonded and (sic)-jacketed CFRP sheets. The effect of CFRP sheets on strength and stiffness of the beams is considered for various orientations of the fibres. The main objective of the Study is to obtain ductile flexural behaviour from the shear deficient RC beams. To verify the reliability, test results were compared with results of ACI-440 design code, Concrete Society TR55, Fib Bulletin 14 and Colotti et al. model.
