This thesis details experimental work and fi-nite part simulation of concrete beams retrofitted with carbon fiber strengthened compound (CFRP).The objectives of this study were to analyze the behavior of retrofitted beams to develop fi-nite part model describing the beams, supportive the fi-nite part model against the experimental results and eventual-ly investigation the influence of chemical compound resins(GP, ISO, Epoxy) on the sweetening of strengthening of retrofitted beams. The experimental results square measure performed to analyze the behavior of beams designed in such approach that either flexural or shear are going to be expected. The beams rectangle measure loaded at exploitation 2 pur-pose bending till cracks square measure developed. The beams were then blank and retrofitted with CFRP. Finally the beams were loaded till failure. The ANSYS program is employed to de-velop finite part models for simulation of behavior of beams.
