Comparison of Main Reinforcement Methods of Bridges

Using reinforcement method to strengthen and maintain the original bridge not only saves a lot of construction funds, but also solves the contradiction between the bearing capacity of the bridge and traffic demand in a short time. At present, the main methods used to reinforce bridges include enlarging section and reinforcing steel bar, bonding steel plate, external prestressing and carbon fiber sheet.

Overloading damage reinforcement for beam and slab structures

After the steel plate is bonded, a 25 mm thick epoxy mortar protective layer is applied on the surface of the beam. For the slab with a width of more than 0.2 mm and the crack-dense area, the cracks on the top of the slab are chiseled out in Fig. 2, showing C.

Structural reinforcement for small and medium span bridges

These structural reinforcement methods are often used in the conventional reinforcement of medium and small span bridges. Due to the limited temporary economic capacity of our country, in order to ensure the safe operation of bridges, the maintenance and reinforcement of bridges is inevitable in a certain period of time.

Carbon fiber reinforced beam and slab structure

Carbon fiber fabric is suitable for reinforcement and repair of various structural types and parts, such as beams, slabs, columns, roof trusses, piers, bridges, cylinders, shells and other structures. The strength grade of base concrete is not less than C15, and CFRP fabric has been successfully used in various beam and slab reinforcement and maintenance in China.

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.

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.
