if the load is removed before the reinforcement of carbon fiber cloth, the situation is completely different. Due to reducing the influence of two times of load and decreasing the lag strain of CFRP, the old and new two parts can enter their respective limit state at the same time, and the overall bearing capacity of the structure can be significantly improved.

The main reasons for structural strengthening:materials reson(unqualified cement quality),design reason(lack of security design),change usage(seismic reinforcement of existing buildings),construction reason(construction method is wrong),environment reason（concrete corrosion，corrosion of steel bar）

In order to protect the life and property, the building have to do seismic strengthening. However, some buildings have not been aseismatic in the design and construction, which requires the seismic identification and reinforcemen . In particular, the old buildings, such as the general hotel, need to be identified as a whole in the new era and to be reinforced in accordance with the design.

the use of the carbon fiber adhesive, can work well, greatly improving the tensile strength of carbon fiber, the carbon fiber reinforcement must first make carbon fiber work together, so the adhesive on CFRP plays a key role, it is necessary to ensure the carbon filaments work together and work together to ensure that the carbon fiber cloth and structure, so as to achieve the objective of strengthening.

Increasing the cross-section reinforcement method for the traditional reinforcement construction method, the main method is applied to the beam stiffness, bending or shear capacity and the difference between the larger enough difference or the original column strength or stiffness of the reinforcement.

Carbon fiber reinfroced polymer(CFRP) fabric is one of the commonly materials used in concrete reinforcement, and externally bonded carbon fiber reinfroced polymer(CFRP) is a new advanced mehod of concrete strengthening. The reinforcement of carbon fiber cloth can repair the structural cracks and improve the bearing capacity of the structure

Under the three circumstances, it is necessary to reinforce the slab: the bearing capacity of the slab is insufficient; the strength of the floor slab is unqualified; the slab is opening.

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.

With the development of construction industry, many buildings come into repair and strengthening period due to various diseases. What are the reasons for building reinforcement?
2018-01-19 19:48:50
there are two advanced structural strengthening methods widely used, bonded steel plate reinforcement and FRP composite strengthening. The reinforcing principles of the two are similar: the structural glue is used to as a reinforcing material, externally bonded on the structure to form an integral structure, and work together
