Retrofitting is a technique to improve the structural capacities including the strength, stiffness, ductility, stability of a building that is found to be deficient. It can effectively improve the performance of a building. In this paper, an RC building of G+3 will be analyzed and design in E-tabs software. Then the number of floors will increase to 3 numbers above the top floor of existing building so that the building becomes G+6 floors and again it is increased by 2 numbers above the top floor of existing building then it becomes G+8 floors. Because of increment of floors the load on the building will be increased so the existing columns may fail in design the failure of columns may be maximum in bottom storey, so how many number of columns fail the same will rectified by Reinforced Concrete jacketing technique, because of jacketing the column strength will increased and the jacketing will be design to carry the increased load by using IS code (IS 15988:2013) and the jacketing will be done in ETABS software. In the software each failed column will be modeled and the increased area of reinforced column can able to take an increased load so the building can be raised to the above-mentioned floors. Hence columns can be strengthened to carry the increased load safely.
