Now-a-days retrofitting is expanding its legs in the world like a wild fire, as many of the historical, public and private important structures get real old and become weak due to flow of time.Retrofitting is one of the best options to make an existing inadequate building safe against future probable earthquake or other environmental forces. Retrofitting is the process of addition of new features to older buildings, heritage structures, bridges etc. Retrofitting reduces the vulnerability of damage of an existing structure during a near future seismic activity. It aims to strengthen a structure to satisfy the requirements of the current codes for seismic design. In this respect, retrofit is beyond conventional repair or even rehabilitation. It is the modification of existing structures to make them more resistant to seismic action, motion of ground, and failure of soil due to earthquakes or other natural calamities such as tornadoes, cyclones, and winds with high velocitycaused by thunderstorm, snowfall, hailstorms etc. Structures lose their strength in due course of time, some structures are important in view of public, social or past importance. Retrofitting helps to increase the strength, resistivity and overall lifespan of the structure.
