Structural strengthening methods for concrete structures

According to the actual situation, the structural reinforcement method of enlarging section, replacing concrete, external stick steel plate, sticking steel jacketing plate and sticking fiber reinfroced polymer(FRP) composite can be selected.

Bonding steel plate or carbon fiber fabric for strengthening

In the structure strengthening, pasting carbon fiber fabric(CFRP) and paste steel plate in the concrete structure is two frequently-used method.

New structural strengthening method of Civil Engineer

According to the different additive properties. The addition of the structural strengthening includes three aspects: bearing capacity (strength) reinforcement, service function (rigidity) reinforcement and durability reinforcement.

Beam bridge superstructure strengthening

There are several kinds of reinforcement and reconstruction techniques for the upper structure of girder Bridges: the expansion and increase of the original structural member section to improve the strength and stiffness of the original structure;To replace the structure of the original resistance with the new structure;The force system of the original structure is changed to reduce the force of the original structure.The prestressing force is applied to the original structure to improve the force performan

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.
