The shear capacity of reinforced concrete T-beam strengthened with CFRP sheet can be significantly improved by anchorage device, and the shear effect (relative control beam) of the strengthened beam can be increased from 21.16% of U-shaped stirrups to 92.55%.

In residential building project, before the construction of cushion layer and surface layer, cracks less than 0.3 mm were found in cast-in-situ concrete slab, and leakage was found after water injection. After core drilling, it was found that the cracks were caused by concrete strength and slab thickness not meeting the design requirements.

The flexural and shear bearing capacity of concrete beams strengthened with CFRP is significantly improved. CFRP can effectively inhibit the development of cracks, and make the width and spacing of cracks smaller.

AFRP composites have a series of advantages, such as light weight, high strength, high modulus, good corrosion resistance, non-conductivity, good impact resistance and so on. Therefore, it has a very wide range of applications in bridge, tunnel, subway, harbor and industrial and civil construction projects, especially in the field of concrete structure reinforcement and repair.

Carbon fiber composite strengthening methods include carbon fiber fabric strengthening and carbon fiber strip strengthening, and carbon fiber strip reinfrocement has many advantages over carbon fiber fabric reinforcement.

FRP composite material have high strength and specific stiffness, to achieve the same reinforcement effec. The size of the composite material is obviously less than the size of the steel plate, after reinforcement, it does not increase the weight of the original structure and the size of the original component.
