Figure 9: Numerical load-deflection curve for S02, S02S, and S02U beams.

Effect of CFRP sheet size for in case of three-layers The predicted load versus mid-span deflection curves for the three layers are provided in Fig. 10. The ultimate load of beam S03 with a 150 mm wide CFRP sheet is 22.50 % greater than that of the control specimen. Table 4 shows that the increase in Pu for beams S03U with 150 mm wide CFRP sheets and S03S with 150 mm wide CFRP sheets was 14.10 % and 14.32 %, respectively.
