Abstract: This study's primary goal is to discuss the impact of the shear strengthening of Confined concrete beams and compare with control unstrengthened specimen to show the impact of side bonded beams retrofitting externally by Cfrp. Beams are designed to show also size effect impact. Two concrete beams were casted at the laboratory with concrete dimension of 180*40*2200mm while casted concrete strength of 30 MPa with 5Φ22 Bottom Reinforcement and 3Φ16 Top Reinforcement while the web reinforcement of T8 Spaced at 150mm.beams are tested under a/d radio of 2. The first beam used as a control beam without strengthening, and the other beam that are externally strengthened with CFRP strips with full height spaced at 150 mm and leaved for 28 days to gain full strength of epoxy resin as per the manufacturer data sheet before testing the beams. Each of these beams was tested with a particular span-depth ratio under a single point of loading until it failed in shear.
Keywords: CFRP, debonding, shear strengthening and concrete beams.
