This paper presents an investigation conducted on repairing damaged Reinforced Concrete (RC) beams with a large rectangular web opening using externally bonded plates. Carbon Fiber Reinforced Polymer (CFRP) and steel plates were used as repair materials with two types of configuration - hexagonal and rectangular - for each material. The beams contain a rectangular web opening at one of the shear spans. The externally bonded CFRP sheet and steel plate were found to be effective in repairing RC beams with a large rectangular web opening. The results showed that CFRP plates perform better than steel plates and that the rectangular configuration is better than the hexagonal one.
