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.
