External bonding steel plate or steel jacketing reinforcement method is a kind of reinforcement method of wrapping steel around reinforced concrete beams and columns. Steel jacketing reinforcement method can greatly improve the bearing capacity of the original member on the basis of increasing the section size of few members.

In fact, in addition to the different modes of stress, the selection of concrete column reinforcement scheme is related to multiple factors. The scheme selection should also take into account the specific characteristics, technical and economic conditions of the original structure.

Reinforcement of reinforced concrete members with embedded prestressed FRP plates can significantly improve the mechanical properties of reinforced concrete members, and its mechanism and effect are similar to that of external prestressed FRP plates.

Compared with single-layer CFRP, double-layer CFRP bears higher tensile stress, so it needs higher performance colloid to ensure the overall force.

Structural strengthening can not only improve the bearing capacity and durability of the structure, but also improve the seismic capacity. So can it be considered that conventional structural strengthening can simultaneously enhance the bearing capacity and seismic capacity, the two can be treated the same?

The tensile strength of the tow is very stable, the dispersion is small, and the coefficient of variation is below 5%. It is easy to control the performance and quality of the tow effectively in the process of production and use.

At present, it is very common to use carbon fiber reinforced polymer (CFRP) composite to reinforce bridges, especially when the structure is in corrosive environment, it is more suitable to use this kind of composite material to reinforce bridges.
