the construction of steel plate strengthened is economical and reasonable. Because of the rapid construction, the construction time is avoided or reduced, and the reinforcement material is saved. Compared with other reinforcement methods, the cost of reinforcement of beam and stick steel is greatly saved

In general, there are several ways in the superstructure strengthening of bridge 1. CFRP reinforcement method 2. Bonded steel plate (tendons) reinforcement method 3. Prestressing FRP reinforcement method 4. Enlarging member section and reinforcing reinforcement method 5. Reinforcement method of rebars planting
