Figure 21: Numerical load-deflection relationship for C2, CF2 and SF2 techniques at  avg.

The numerical results of load-mid span deflection for C2, Cf2 and SF2 beams are presented in Fig. 21 at  avg . Typical behaviors of linear and nonlinear response were found as in case of  min with an increase in the value of Pcr and Pu as compared to  min due to increase in the ratio of steel reinforcement. On the other hand, the values of cracking and maximum deflection were decreased as compared to those of  min . Fig. 22 a, b and c show crack pattern for beams at steel reinforcement equal to  avg.

a) Control beam, C2.

CFRPs DEBONDING

b) Carbon fiber reinforced polymers technique, CF2.
