Strengthening/repair of existing reinforced concrete structures has become one of the important issues in the field of civil engineering. Corrosion of reinforcement in Oman and the Middle East region is a serious problem and is the main cause of concrete structures deterioration costing millions of dollars even though the majority of such structures are at the early age of their expected service life. This paper presents the experimental results of damaged/repaired reinforced concrete beams. The experimental program consisted of reinforced concrete rectangular beam specimens reinforced with flexural reinforcement only without shear reinforcement and exposed to accelerated corrosion. The corrosion rate was varied between 5 to 7.5% which represents loss in cross sectional area of the steel reinforcement in the tension side. Damaged beams were repaired by bonding Carbon Fiber Reinforced Polymer (CFRP) U-straps and in some by CFRP sheets to the tension side to restore the strength loss due to corrosion. Test results showed that it is possible to use external shear reinforcement to enhance the strength of damaged concrete beams. In addition, combining U-straps and CFRP sheets is very effective to restore the lost strength in corrosion damaged beams.
