As time goes up, structural capacity of members decreases in reinforced concrete structures. The deterioration of the capacity is mainly due to the corrosion of materials, poor construction and environmental pollution, etc. This deterioration is unavoidable, thus it is necessary to develop the method for repair and retrofit of structures in order to ensure structural safety of members The purpose of this paper is to investigate the load-deflection, ultimate strength, failure mode, and energy absorption capacity of reinforced concrete columns strengthened with angle and bolt tension, and evaluate the degree of their strengthening effect. For the test, the specimen size of column is 20cm x 20cm x90cm reinforced with 4 number of main bars of 13 mm diameter, tied bars of 6 mm diameter The test results show that the increasement of bolt and bolt tension’s Quantity improve the ultimate strength and energy absorption capacity
