Abstract :
    Abstract In many cases, reinforced concrete structures need repair and repair due to changes in operating loads, user and operation modifications, computational errors, faults and imperfections, and failure to meet design requirements during execution. The Federal Emergency Management Agency (FEMA) for the upgrading of structures has evaluated the methods of rebuilding existing buildings and providing retrofitting methods. It can be noted that reinforcement and retrofitting, bearing more load and eliminating structural weakness. Fiber-reinforced polymer (FRP) is one of the materials used in civil engineering to repair and strengthen the structure. FRPs are durable, durable, lightweight materials, and the relatively thin thickness of these sheets makes them more efficient and easy to use. Among the weaknesses of these sheets are short life and fire resistance and weakness against stresses. This paper reviews the methods of maintenance of concrete structures by FRP fibers according to the standards defined by the Federal Emergency Management Agency (FEMA).
