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 member
of the bridge
• Change in load rating method

34. Need of Innovations in Construction Materials
Infrastructure Decay Problems in Developed Countries
- More Durable Materials should be Developed
- Efficient and Effective Repair Materials are Required
Rapid Growth in Developing Countries (e.g., China)
- Requirements on Material Durability, Sustainability
as well as Construction Efficiency
Improvement of Living Quality
- Functional Materials that are Self-Cleaning,
Sound-Proof, etc
45. 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. Fibres
2. Matrix (Resin, Fillers & Additives)
46. 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.)
