Comparison of Bridge Reinforcement Schemes: Pre-stressed carbon fiber plate vs steel plate reinforcement

Prestressed carbon fiber plate for bridge reinforcement


Prestressed carbon fiber plate for bridge reinforcement


Prestressed CFRP System(Post-tension CFRP system) includes anchoring devices and CFRP strip specially designed for bridge or long span beam reinforcement.


• improve the bearing capacity of bridge structure,has incomparable advantages in large-span beam slab of flexural reinforcement.

• significantly reduce deformation of the structure and improve the bearing capacity of structure,decrease the crack width and deflection deformation,and is suitable for large span beam slab of flexural reinforcement.

• improve the stiffness of structure ,and make full use of the material performance ,save a lot of materials and engineering cost.

steel plate for bridge strengthening


Steel-bonded reinforcement is the use of high-performance epoxy adhesives to bond the steel plate to the surface of the concrete member, so that the steel plate and concrete form a unified whole, and the good tensile strength of the steel plate is used to achieve the purpose of enhancing the bearing capacity and rigidity of the member.

Pre-stressed carbon fiber platesteel plate reinforcement
Reinforcement material stress methodActive reinforcement, significant reinforcement effect

Passive reinforcement, general reinforcement effect

Increase in structural weight

Small increas

Increase more

Difficulty in construction

The construction is simple, quick and short in construction period

The difficulty of construction is greater, and the speed of construction is slower

Traffic impact

It has little impact on traffic and can quickly restore traffic

Need to interrupt long-term traffic

MaintenanceAfter being reinforced, the bridge girder has strong durability and less maintenance in the later periodLarge amount of maintenance work such as anti-corrosion and rust removal
