The basic principle of bridge reinforcement
Because of structural failure or damage, when it can not meet the requirements of structural safety or normal use, the bridge structure must be strengthened.6) The reinforcement design should be closely combined with the construction method, and take effective measures to ensure that the new and old structures are connected reliably and can work together.

Section-enlarging Reinforcing Method for Concrete
Enlarged cross section method is a method used to increase the components of the structure or increase the components of the reinforcement area , not only enhance the bearing capacity, but also can increase its cross section stiffness and change the natural frequency of vibration, the normal use of stage performance is improved, the reinforcement method is widely used in reinforced concrete structure of the beam, slab, column, etc.

Reinforcement of old factory buildings
In the absence of changing the original structure, it is decided to reinforce the column,beam and slab with carbon fiber reinfroced polymer (CFRP).

The difficulty of the old building reinforcement
The difficulty of the old building reinforcement and retrofitting:1. Short construction period；2. Many obstacles of strengthening design；3. More difficulty in construction；4. High security requirements

Houjie plant reinforcement project
The building should be reinforced and retrofitting into industrial factory building of the first and thecond level, and third to five floors for the office building.A large amount of reinforcement and repair construction of the foundation, column, beam, plate and other components which are not satisfied with the requirements of standard and safe are carried out.

Wall and floor openings strengthening
According to the requirements of the standard, the reinforcement of the concrete structure should be strengthened when the opening of the concrete structure is more than 300*300mm. In order to ensure the stability of the original structure, the shear wall and floor of this project are 300*400mm and 400*700mm, which should be strengthened according to the requirements of the standard.
