Abstract: Retrofitting can increase a building's structural qualities, including its strength, stiffness, ductility, and stability. Due to the probable design problems in the current columns and the increasing strain the building will receive as the number of retailer’s increases, the bottom story may experience the greatest amount of column failure. As a result of the jacketing process, the columns will become stronger and the jacketing will be constructed to sustain the greater load in accordance with IS code, reducing the number of columns that fail (IS 15988:2013). The structure may rise to the aforementioned floors because the strengthened columns' bigger surface area can withstand a heavier load. The software will model every unsuccessful column. A common refit technique is concrete jacketing. The concrete junketing’s design and computer-aided modeling are crucial components of the retrofitting procedure to be used on an existing structure. Particularly in India, there aren't enough laws and norms governing retrofitting. Use the structural engineering tool ETABS to analyze multi-story buildings for seismic loads, and then present retrofitting options to reduce the building's overall displacement and raise the frequency of seismic vibrations.
