Four damaged concrete filled steel tube columns strengthened with carbon fiber reinforced plastics（CFRP） and four contrast columns were tested. All specimens were notched in the central zone to simulate the loss of section due to corrosion. All specimens were axially loaded while strain and displacement were measured to demonstrate the effectiveness of this repair concept. Influences of the CFRP confinement and the aspect ratio on the load bearing capacity of the columns are analyzed. The test results show that within the scope of the test, CFRP would enhance the load bearing capacity of the damaged concentrically compressed concrete filled steel tube columns effectively; the increase rate of load bearing capacity due to CFRP decreases with the increase of aspect ratio. A calculating method is also presented, capable of predicting the axial load strength of concrete filled CFRP steel tube members. Experimental results are in good agreement with the predicted values.
