| Abstract: | Study was made on the repair and strengthening of damaged tubular concrete elements with carbon fiber material. On the basis of the study, basic equations were derived for the rational quantity of strengthening of the concrete elements and the ultimate bearing capacity of the concrete elements after the repair. A simplified equation applicable for engineering projects was then derived on the basis of the basic equations and the reliability of the equation was also verified by corresponding loading tests. |

| Keywords: | carbon fiber concrete tubular pile ultimate bearing capacity |
