Concrete beams, which have insufficient bending and shear strengths, were strengthened wrapping them with Carbon Fiber Reinforced Polimer (CFRP) in this study. The work was implemented on the rectangular section beams that were observed to requiring reinforcement after the examination and statistical analysis conducted. The aim was to strengthen beams that have insufficient shear strength values. Three among the nine used for the examination, was reinforced by using CFRP and epoxy in the tension surface whereas another three of them was reinforced by wrapping CRFP with 45 angle in the shear. The remaining three beams, on the other hand, were used as the reference beams. The reinforced beams were tested under the loading on the four points. The values were then compared with the reference beams' values. As a result of the test; the strength was observed to increase with a 40% whereas a small increase was determined when rigidity and energy consumption values were determined.
