CFRP strengthening method 

In addition to the advantages of similar stickup steel plate, it also has the advantages of corrosion resistance, moisture resistance, almost no increase of structure weight, durability, and low maintenance costs, but it needs special fire prevention and treatment. It is suitable for concrete structures and general structures of various material.

Bonding steel plate reinforcement method

It has little influence on production and life, and has no significant influence on the appearance of the original structure and the original clearance, but the reinforcement effect depends on the adhesive process and operation level to a great extent.

It is suitable for reinforcement of flexural or tensile members subjected to static and normal humidity.

Enlarging the cross section method

The method is simple and adaptable, and has mature design and construction experience.

Reinforcement of concrete for beams, plates, columns, walls and general structures.

However, the wet operation time of site construction is long, which has a certain impact on production and life, and the clearance of reinforced buildings will be reduced.

Anchorage method

This method is applicable to the transformation and reinforcement of the concrete bearing structure with the strength grade C20~C60.

It is not applicable to structures and lightweight structures that have been seriously weathered.

Displacement concrete method

The advantages of the method are similar to that of the enlarging section method, and the clearance of buildings will not be affected after reinforcement.

It is suitable for reinforcement of concrete bearing members such as beams and columns with low strength or serious defects in compression area.

Winding reinforcement method

The advantages and disadvantages of the method are similar to that of the enlargement section method.

It is suitable for reinforcement of concrete structure members with insufficient bearing capacity of oblique section or lateral restraint on compression members.
