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. Then the number of floors will be increase to 1 numbers above the top floor of existing building so that the building becomes G+4 floors. Because of increment of floors the load on the building will be increase 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 be 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 raise to the above mentioned floors. Hence columns can be strengthened to carry the increased load safely. Also we repair cracks on surface of elements and walls.
