When Should a Load Rating be Performed?
• Design stage
• Initial inventory inspection
• Change in the live loading
• Change in the dead load on the structure
• Physical change in any structural memberof the bridge
• Change in load rating method

Need of Innovations in Construction Materials
Infrastructure Decay Problems in Developed Countrie s- More Durable Materials should be Developed- Efficient and Effective Repair Materials are Requi red
Rapid Growth in Developing Countries (e.g., China)- Requirements on Material Durability, Sustainabilit y
as well as Construction Efficiency
Improvement of Living Quality- Functional Materials that are Self-Cleaning,
Sound-Proof, etc

What is FRP?Composite = combination of two or more materials to form a new and useful material with enhanced properties in comparison to the individual constituents (concrete, wood, etc.)
� FRPs consist of:1. Fibres2. Matrix (Resin, Fillers & Additives)
Uses of FRP in Construction
1. Internal reinforcement of concrete
2. External strengthening of concrete
Corrosion of steel reinforcement in concrete structures contributes to infrastructure deterioration
Use non-corrosive FRP reinforcement
Provide external tension or confining reinforcement (FRP plates, sheets, bars, etc.)
