In this article the results of experimental study of reinforced concrete columns strengthened by reinforced concrete jacketing are produced. Reinforced concrete jacketing was chosen as the strengthening method since it is the most commonly used for reinforced columns repair and strengthening. The design of such strengthening will differ from basic column design methods since the impact of the load supported by the existing structure during strengthening should be taken into consideration. Determination of the impact of that factor is the main objective of this research.
