Common structural strengthening method for reinforced concrete structure

1.Enlarging section reinforcement method

In order to improve the load-bearing capacity, stiffness, stability and crack resistance of the original member by adding the reinforced concrete to the outer section of the component section and adding the reinforced bar or structural reinforcement.The slenderness ratio and axial compression ratio can also be reduced for compression members. Therefore, it is often used for reinforcement of beams, columns, plates and foundations.

2.Steel plate strengthening

The sticking steel plate method is a reinforcing method for improving the bearing capacity of components by using structural glue to paste steel plates on the surface of concrete components.

3.FRP composite strengthening

With structural adhesive externally bonded FRP fabric or FRP lamiante to the surface of the reinforced component. The purpose of improving the bearing capacity and ductility of the structure is to use the high tensile strength and tensile modulus of the fiber composite material to improve the structure’s bearing capacity and ductility.
