In general, there are several cases of slab reinforcement:

1. Floor bearing capacity is insufficient (usually increasing load on the floor, such as increasing equipment);

2. Unqualified strength of floor concrete

3. Floor openings.

The CFRP sheet is bonded to the tension part of the bottom of the plate along the transverse direction of the plate by structural glue, and the end of the sheet must be anchored reliably. The advantages of CFRP are light weight, high strength, multi-layer bonding, no increase in the weight of the original components, and no impact on the shape of the structure. It can not only improve the bearing capacity of the structure, but also enhance the stiffness of the structure.
