FRP composite strengthening system in bridge engineering
The bridge structure in the tension side with the reinforcement method of epoxy resin bonded CFRP materials, has simple construction, low cost of strengthening (instead of steel reinforcement can save money 25 %), does not reduce the clearance under the bridge reinforcement materials

Advantages of FRP composite bridges
FRP composite has the advantages of light weight, high strength and strong corrosion resistance, making it a substitute for steel and prestressed tendons in concrete bridges.With the decrease of the cost of the fiber composite industry, the scale of its application in bridge structural engineering will continue to expand.

What is the difference between structural strengthening adhesive
The structural strengthening adhesive has high strength (compressive strength >65MPa, steel steel tensile bonding strength >30MPa, shear strength >18MPa). It can withstand large loads, and is resistant to aging, fatigue and corrosion. It has stable performance in the expected life and is suitable for bonding with strong structural member.

Can FRP strengthening be interchangeable with steel plate?
Fiber reinfroced polymer(FRP) and steel plate reinforcement are all similar of bonding form and strengthening mechanism. Essentially, they are equivalent to increase the reinforcement of members, and they can replace each other in shear and flexural strengthening.

Why load is removed in the process of strengthening?
In order to make the new and old structure to bear force together, should first remove the original structure load before the reinforcement. It is a better way to reapply it after reinforcement.
