Reinforcement technology for quality defects of RC column
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 .

Strengthening of wood structure by FRP composite
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.

Structural strengthening or insufficient strength of concrete
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.

Mechanical analysis on CFRP sheets strengthening
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.

Measures for quality problem of CFRP strengthening
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.

18 methods for seismic strengthening
When the aseismic bearing capacity of the building fails to meet the requirements, the following reinforcement and transformation methods can be chosen

Seismic reinforcement of concrete structures
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.

Bonded steel plate reinforcement method
In construction, the steel plate will be attached to the outer edge of the stressed part of the reinforced structure with structural steel plate bonding adhesvie, in order to give full play to the strength and effect of the steel plate, and to close the cracks in the pasted parts at the same time, to restrain the deformation of the concrete, and thus effectively improve the crack resistance and stiffness of the reinforced component.

Cracks in reinforced concrete(RC) structural members
Structural cracks not only represent the structural stress, but also affect the durability of structures. The bigger the crack width is, the easier the steel will corrode, which means that the bond between the steel bar and the concrete has been completely destroyed and the service life has come to an end.
