FRP strengthening or steel plate reinforcement
In structural reinforcement, FRP composite strengthening and steel plate strengthening are two commonly used methods in concrete structures. In the selection of reinforcement schemes, the two methods often appear simultaneously. From the point of view of the mechanism of action, the two reinforcement methods are formed by structural adhesive and concrete base material as a whole, and the two methods are similar in construction technology, often causing certain obstacles to the choice of methods.

Carbon fiber for structural reinforcement
Carbon fiber structural reinforcement technology is suitable for various types of structures, various structural parts of the reinforcement and repair, such as beams, slabs, columns, roof trusses, piers, bridges, cylinders, shells and other structures. The strength level of base concrete should be no less than C15. In addition, some mechanical properties of brick masonry can also be strengthened with carbon fiber.

RC beams strengthened with FRP laminates
The ultimate bearing capacity of concrete beams strengthened with FRP laminate is related to the initial stress level. The ultimate bearing capacity of concrete beams strengthened with FRP laminate is the largest when the initial stress is zero. The loading capacity of beams strengthened with fiber materials is the minimum when loading to 50% without unloading.

FRP reinforcement for bending members
The bridge has already entered the reinforcing and repairing period. The application of FRP to reinforce the bridge can effectively improve the corrosion resistance and strength of the bridge.

FRP to reinforced concrete structures
The corrosion of the corroded damaged columns strengthened with FRP can be greatly reduced by corrosion, but the corrosion of the reinforcement in concrete can not be completely prevented.

FRP strengthening technology in bridge retrofitting
FRP composite strengthening of the bridge is similar to that of bonding the iron plate to the bearing edge of the cement component by chemical bonding agent, so that it can bear the supporting and compressive functions together with the bridge components, and then enhance the deformation resistance and bearing capacity of the bridge structure.
