What is the principle of aramid fiber cloth to reinforce the bridge structure? It acts on the compression, tension and shear reinforcement of concrete members.

For the purpose of reinforcement, the principle of reinforcement is different:

1) Shear resistance VAFyd= Vc + Vs +VAfd
Among them, VAfyd is the design shear strength of concrete members, Vc is the shear resistance of simple concrete, Vs is the shear resistance provided by steel bars, and VAfd is the shearing capacity that aramid fiber cloth can withstand.

2) Bending and compression If the interface crack does not occur and the interface peeling damage occurs, the general reinforced concrete design theory can be applied to the aramid-reinforced steel-concrete structure. However, if the above situation occurs, the bending strength value of the reinforced concrete beam estimated by the conventional beam theory is reduced, and the reduction factor is 0.9. In addition, when the axial compression design is performed, if the fiber cloth is used for the circumferential direction, the axial compressive strength and ductility of the structure are increased.

3) ductility uAFd=2.2+3.2 (VAFyd·la / MAFyd)
Where uAFd is the design ductility of the component, 2.2 and 3.2 are empirical constants (refer to Japanese specifications), VAFyd is the design shear strength, MAfyd is the design bending strength, and la is the shear span ratio of the component.

The above can be used as a design principle or as a basis for evaluating various reinforcing performance after component reinforcement. The fiber cloth is adhered to the surface of the concrete with a resin, and the high-strength characteristics of the fiber cloth are fully utilized to bear the load together with the concrete.



Glitter carbon fabric

Glitter carbon fabric is a type of fabric that is made by incorporating carbon fibers into the material. It is known for its unique glittery appearance, which is achieved by adding metallic or shimmering particles to the carbon fibers during the manufacturing process.
