Fiber reinforced polymer(CFRP) fabric reinforced bridge members have the advantages of light weight, high strength, high elastic modulus, corrosion resistance, good durability and impact resistance.
Key points for design and calculation of carbon fiber reinforcement fabric for bridge strengthening
1.
At present, the calculation method of CFRP reinforcement for old bridges is generally based on the standard of CFRP.
For example, the stress standard is allowed to be approximately converted into a certain amount of steel, and then, according to the traditional analysis model of the reinforced concrete stress analysis, although it is an approximate calculation method, the theoretical analysis results are in perfect agreement with the experimental data. Therefore, in general, it is applicable.
2.
The amount of carbon fiber reinforcement can be estimated by the press.
Acf - The amount of carbon fiber cloth (area);
Ag - The area required for resisting insufficient bending moments;
Rg - The tensile strength of the steel bar;
Rcf - The tensile strength of carbon fiber cloth.
3.
In addition to the amount of CFRP reinforcement calculated according to the above formula, consideration must also be given to:
Necessary anchorage length
The area required for lap length
Cutting loss, such as necessary side, corner waste, and so on
