There are many researches on the normal section, oblique section bearing capacity, bearing capacity and ductility of the flexural members strengthened by CFRP, and the design and calculation methods can be more mature. However, the above calculation methods are based on the CFRP cloth and concrete bond firmly, CFRP cloth strain reached the allowable strain before peeling failure.

There are many researches on the normal section, oblique section bearing capacity, bearing capacity and ductility of the flexural members strengthened by CFRP, and the design and calculation methods can be more mature. However, the above calculation methods are based on the CFRP cloth and concrete bond firmly, CFRP cloth strain reached the allowable strain before peeling failure. But experiments show that. The effect of CFRP cloth on strengthening concrete structure is closely related to the bond performance between CFRP and concrete, and the stripping failure of CFRP cloth is a common form of failure, which is very sudden, brittle, and the use of CFRP cloth is also poor.
