Recently, strengthening and repairing concrete structures are increasing due to the deterioration of concrete infrastructures. Carbon Fiber Reinforced Polymer Plastic (CFRP) system for strengthening concrete structures have emerged as an alternative to traditional strengthening techniques, such as steel plate bonding, section enlargement, and external post-tensioning. CFRP systems offer advantages over traditional strengthening techniques such as lightweight, noncorrosive, and relatively easy to install. In this paper, we present the structural design algorithm for the RC beams strengthened with CFRP sheet based on ACI 440. In addition, structural behavior of strengthened RC beams is investigated by varying the amount of CFRP sheets.
