The main variables considered in this work were the internal reinforcement ratio and position of the strengthening. The result of this work generally indicates that beams strengthened by CFRP laminates are structurally efficient and were upgraded to more load carrying capacity. The deficient beams showed more softening due to crack propagation, whereas the beams, when strengthened by the laminates lost partial ductility. The maximum two point loads in which the beam deficient in flexure failed was recorded as 120 kN, and this load for the beam deficient in flexure and strengthened by CFRP laminates got enhanced to 168 kN. The corresponding loads for beam deficient in shear was 115 kN, whereas this load for the beam deficient in shear and strengthened by CFRP laminates increased to 167 kN. It is encouraging to note that about 40% increase in load carrying capacity for the beams deficient in flexure and strengthened by CFRP laminates, and about 45% increase in load carrying capacity for the beams deficient in shear and strengthened by CFRP laminates is attained.
