Structural strengthening are different from the new construction

The structural strengthening works are aimed at the existing projects, which are subject to objective conditions, and reinforce the design and construction according to the existing conditions.

Reinforcement of concrete beams with prestressed CFRP

Compared with the traditional carbon fiber reinforcement method, the high strength performance of the prestressed CFRP can be effectively used. The reinforcement effect is greatly improved than the CFRP, and it also has the advantages of CFRP reinforcement. It has shown remarkable effects in improving the flexural rigidity, bearing capacity, reducing the structural deformation and restraining the development of cracks.

Three sentence tells you why need to reinforce existing building

The construction reinforcement and reconstruction means that the existing building should adopt reasonable reinforcement and repair measures on the basis of scientific testing and identification for some reasons, or improve the safety and durability of the original structure by structural transformation.

Effectiveness of CFRP reinforcement for cracked brick walls

It is very effective to reinforce the cracked brick walls with CFRP sheets. The ultimate load of cracked wall strengthened with CFRP is significantly higher than that of unreinforced wall.

The difference between FRP strengthening and bonded steel plate

According to the design of equal strength, the glue dosage of the two schemes is equivalent. The FRP strengthening are much cheaper than the sticky steel plate. The cost of the two schemes is flat when short carbon fiber fabric are taken.

What is retrofitting? why need retrofitting?

Retrofitting, refers to inadequate reliability or owner for higher reliability of the bearing structure, component part and its related to enhance, local replacement or adjustment measures such as its internal force, to make it with the current design specification and the owner required safety, durability and applicability.
