Many of the existing bridges are in need of repair and strengthening due to various reasons including design flaws, fatigue and deterioration of steel reinforcement, increase in traffic volume, and accidental impact loads during collisions between vehicles and bridge girders or piers. The use of fiber reinforced polymer (FRP) materials to repair and strengthen the deficient infrastructures has become very popular due to FRP’s well known advantages such as high strength-to-weight ratio, corrosion resistance, light weight, and ease of applications. This paper presents a review of existing experimental investigations and field applications of FRP-strengthened reinforced concrete structures. Various FRP retrofit techniques are also discussed. A Finite Element Model (FEM) of a prestressed reinforced concrete beam is modeled based off an experimentally tested beam. The model is intentionally damaged by cutting two prestressing strands and one mild steel bar. The beam is repaired with three layers of Carbon Fiber Reinforced Polymer (CFRP) to recover the original design strength of the beam.
