Effectiveness of CFRP reinforcement for cracked brick walls
It is very effective to reinforce the cracked brick walls with CFRP sheets. The ultimate load of cracked wall strengthened with CFRP is significantly higher than that of unreinforced wall.

Mechanical analysis on CFRP sheets strengthening
Carbon fiber reinfroced polymer(CFRP) sheet can improve the shear capacity of concrete beams, the mechanism of which is similar to the stirrup, and it can also improve the deformation properties of the components and enhance the deformation capacity of the components.

Carbon fiber fabric reinforced brick masonry chimney
The cracks are first treated by grouting and sealing, so as to restore the integrity of cracked masonry, and then reinforce the treatment with carbon fiber fabric. After strengthening, it has been used for more than a year, and no new cracks have been found

Structural strengthening or insufficient strength of concrete
The lack of concrete strength caused by improper construction and use will reduce the bearing capacity and stiffness of the structure, increase the deflection and deformation, and reduce the crack resistance, seepage resistance and durability of the structure, which will affect the use of the structure.

Fiber reinforced polymer(FRP) strengthening technology
Sticking FRP in the tensile area of concrete structure can effectively improve its bearing capacity and restrain crack propagation. The damage characteristics of the reinforced concrete structure after the FRP reinforcement are different from that of the ordinary concrete structure and the reinforced concrete structure, and the calculation method of its bearing capacity is different.
