Advanced composites in bridge construction and repair
The advanced composite materials have the advantages of corrosion resistance, light weight (1/5 to 1/4 of the bulk density of steel), high strength (the strength is higher than the high strength steel wire or the equivalent).

Prestressed FRP laminate is widely used in bridge strengtening
For the problems brought about by the strengthening of carbon fiber reinforced material, the reinforcement method of Prestressed CFRP laminate can be solved by applying a pre stress to the carbon fiber plate, and then anchoring it on the reinforced component.

Construction operation of CFRP U shaped hoop
The CFRP U - shaped hoop is a U - shaped stirrup made of carbon fiber fabric. In order to fix the carbon fabric of the bottom of the beam and transfer the reliable force, when the CFRP is strengthened, the carbon fiber cloth U shaped hoop is often pasted, and the strip is not allowed only on the side of the beam.

Stress analysis of structural strengthening by FRP wrap
In bridge reinforcement projects, fiber reinfroced polymer(FRP) wrap is mainly to improve the flexural capacity of the component, the shear bearing capacity and the axial compressive bearing capacity of the compression member, and to improve the stiffness and ductility of the component, the crack width of the reinforced concrete member can be controlled.
