In addition to the reasons for the poor column quality caused by the above mentioned construction, in practical engineering, the loading capacity of reinforced concrete columns is often insufficient because of poor design and disaster (earthquake, fire, flood), or the increase of the load to the column due to the change of the structure's function. When these conditions occur, strengthening reinforced concrete columns is need .

There are also some problems in the modern wood structure, such as carrying capacity. Therefore, the fiber reinfroced polymer(FRP) material reinforcement method is put forward.

The lack of concrete strength caused by improper construction and use will reduce the bearing capacity and stiffness of the structure, increase the deflection and deformation, and reduce the crack resistance, seepage resistance and durability of the structure, which will affect the use of the structure.

Carbon fiber reinfroced polymer(CFRP) sheet can improve the shear capacity of concrete beams, the mechanism of which is similar to the stirrup, and it can also improve the deformation properties of the components and enhance the deformation capacity of the components.

When the bonding quality is not required, the carbon fiber fabric should be cut off along the edge of the empty drum. The size of 100mm is extended to the outer edge of the same carbon fiber material, and the same binder is used in the original.

When the aseismic bearing capacity of the building fails to meet the requirements, the following reinforcement and transformation methods can be chosen
2018-06-28 16:17:52
If the bearing capacity of the building structure can meet the requirements, it is preferable to adopt the method of changing the structural system instead of reinforcing its components. When reinforced concrete structural members are required strengthening, the reinforcement method adopted in the design shall comply with the following table rules.
