Prestressed carbon fiber plate vs steel plate reinforcement

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

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

Item	Pre-stressed carbon fiber plate	steel plate reinforcement
Reinforcement material stress method	Active 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
Maintenance	After being reinforced, the bridge girder has strong durability and less maintenance in the later period	Large amount of maintenance work such as anti-corrosion and rust removal
