In this study, the effect of strengthening RC beams in shear on its ductility, toughness, and strain in main reinforcing steel was studied. Beams were strengthened using GFRP-U strips. The variable studied were width of GFRP and spacing of such strips measured from centerline to centerline. Ductility in terms of mid span deflection was found to decrease as the GFRP surface area increases. The same result was reached at for toughness of specimens measured in terms of the area under the load deflection curves of the specimens. Maximum strain in reinforcing steel decreases with the increase of GFRP strip width or decrease spacing between GFRP strips, which could be attributed to the increase of specimens' stiffness.
