Whether it is a building or a structure, the most important load-bearing component of a building structure is the column structure, and the reliability and comfort of the building are closely related to it. Reinforced concrete columns are currently the most used column structure in the main structure of buildings and structures in my country. The development of the engineering field in our country has gradually transitioned from the first phase dominated by a large number of new projects to the second phase where new projects and maintenance and renovation projects coexist. Therefore, how to reliably strengthen buildings while occupying less resources is an important research topic in the current scientific research field.

CFRP cloth wrapping and wrapping confined concrete columns can effectively improve the axial compressive bearing capacity of the columns. The use of CFRP-confined concrete can significantly increase the compressive strength of concrete and improve the ductility of concrete. At the same time, for concrete structure reinforcement and reconstruction projects, CFRP reinforcement concrete column technology has many advantages. (High strength, light weight, durability, easy construction, etc.). The reinforcement method of CFRP reinforced concrete columns has been applied in more and more practical projects.

In projects where carbon fiber cloth is used for reinforcement and transformation, due to cost and construction considerations, many structures currently use carbon fiber cloth and strips for reinforcement. In many practical projects, carbon fiber cloth and strips are also used for modification and reinforcement, and they have also been proved in improving the bearing capacity and ductility of structural members. The use of carbon fiber cloth and strip reinforcement can effectively increase the utilization rate of carbon fiber and has good economic benefits. Especially in terms of construction, the use of carbon fiber cloth and strip reinforcement has very little requirements on the construction site and construction space, and can effectively and flexibly organize the construction.
