Because the price of carbon fiber materials has decreased,and carbon fiber materials have the characteristics of high strength,low quality,simple construction and easy operation,carbon fiber as a new material has been widely used in the field of civil engineering.In order to study the com-pression behavior of reinforced concrete columns with carbon fiber cloth,ANSYS was used to nu-merically analyze the reinforced concrete,and compared the change of compressive strength of un-reinforced reinforced concrete cylinders and reinforced concrete columns reinforced with carbon fi-ber cloth,as well as the compression resistance of different carbon fiber cloth layers components.What is the impact of intensity.The results show that the reinforced concrete cylinder reinforced by the full-wrapped ring-oriented constraint method with carbon fiber is stronger than the unrein-forced reinforced concrete cylinder.The compressive capacity of reinforced concrete cylinders in-creases with the increase of the number of carbon fiber cloth layers,and the proportion of com-pressive resistance of reinforced concrete columns is decreasing.
