The optimum length for FRP shear strengthening of RC beams subject to uniform distributed load. Is it logic ?

I`m conducting a parametric study using FE abaqus on RC beam shear strengthened with externally side-bonded CFRP. The optimum length which i get is 0.36L, where L is the beam length. Is this...
