Retrofitting means modifying structures with additional or new components or members. It refers to the addition of new technology or features to older system. Retrofitting of a existing building can be more cost effective than the newly constructed building. It adopts new technology and provides better features to older systems. Retrofitting is the modification of existing building to resist seismic activity, soil failure due to earthquakes and grounds motion. The retrofit techniques are also applicable for other natural hazards such as tornadoes, tropical cyclones etc. Many structures were earlier constructed without detailing and reinforcement for seismic protection. After year of research, the retrofit and rehabilitation has been found and used across the world. In retrofitting we have to install a system in building after the construction of building. These systems are heating system, cooling system, integrated design process etc. In retrofitting system we have to upgrade the energy performance of commercial building and improve energy efficiency (reduce the operational costs) or decrease the energy demands. Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. The retrofit techniques outlined here are also applicable for other natural hazards such as tornadoes, tropical cyclones and severe wind from thunderstorm. It is also important to keep in mind that there is no such thing as an earthquake proof structure, although seismic performance can be greatly enhanced through proper initial design or subsequent modifications.
