Advantages of Prestressed Reinforcement Technology in the Reinforcement of Factory Building Steel Structure

1. The reinforcement work can be carried out without unloading or stopping production;

2. Applying prestress can directly reduce deformation, rapidly eliminate overstress and peak internal force;

3. It can eliminate the stress hysteresis, make full use of the high strength characteristics, and improve the reinforcement efficiency.

4. It can reduce the peeling stress of bonding interface, avoid overall peeling, and improve the reliability of reinforcement;

5. Reduce the reinforcement cost and application cost.

The damage of steel structures is characterized by locality and multiple occurrences. These structures cannot be retired immediately when damage occurs. Therefore, seeking an economic and efficient steel structure reinforcement technology is not only a technical problem to be solved in the field of civil engineering, but also a problem related to the sustainable development of society.
