Refinement of concrete bridges using FRP fibers

In recent years, efficient and economical methods have been developed to reinforce the pillars and bridges. Methods such as the use of sheets to enclose and prevent the sealing of concrete from the oldest of these methods. Among those who have been involved in this research, we can mention. FRP or reinforced polymer fibers is a composite material that consists of two parts of the fiber that plays the role of composite load as well as the adhesive (resin), which plays the role of keeping the fibers together. The main function of the fiber is to provide hardness and strength in the reinforced member. The most common type of fiber used in the manufacture of composites, carbon fibers, glass fibers and aramid fibers. The fibers have a very high tensile strength and the stress-strain behavior of these fibers is linear.
