Seismic retrofitting will be the modification of existing structures to all of them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better associated with seismic demand on structures and along with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Earthquake engineering is applied for the seismic retrofit of structures that involves alteration of existing structures to obtain resistance to seismic activity or soil failure due to earthquakes. Retrofit is now widely performed, especially inside the active seismic zones.

Seismic retrofitting is an area of construction engineering that focuses along the modification of existing structures to boost their capability to face up to earthquakes. It is achieved the particular inclusion of structural improvements that may prevent the building, people, as well as the equipment from damage by seismic ocean. In seismic zones, retrofitting may be essential for bridges, overpasses, tunnels, and buildings. While new construction would require compliance to seismic values.

Seismic retrofitting may be executed on concrete masonry, unreinforced masonry, soft story and concrete tilt-up material. Soft story building is a multi-story building with abundant open space and in concrete tilt-up construction. Concrete is filled in the panels that make up the walls of the structure. Since the concrete tilt-up walls tend to be heavy, seismic retrofitting the necessary. The motive for the concrete tilt-up retrofit is to prevent the separation with the roof contrary to the building inner walls.

There are some categories of seismic retrofitting and their nature depends upon the purpose for the fact that retrofit is executed. Appropriate form may be the public safety retrofit involving structural reinforcement to save human life though some amount of injury is acceptable. Such retrofit is performed on structures aren't extremely expensive and where a complete rebuild isn't desired. A lower level retrofit may be selected in order that earthquake endurance of framework with some repairs needed after the earthquake. Extensive retrofit the essential for buildings which have been important due to cultural, historical or some other reasons. Mostly, retrofit is performed on buildings that are extensively high, with an unhealthy earthquake vibration frequency. Roads also have a priority in retrofit as their service necessary during an earthquake to guarantee the function of emergency specialists.

There are many techniques in which used for the seismic retrofitting of architecture. Their selection is based more than a objective of retrofit, connected with structure, soil conditions and the expenditures attached. Seismic retrofitting of buildings may reduce the earthquake damage by suitable structural modifications, but no technique will completely remove risk of seismic swells throughout the year. Reinforcement of the buildings by means of girders and trusses are normally implemented to make the buildings safe. Base isolators are utilized to decouple the structure from the shaking ground, thus achieving seismic vibration control. Supplementary dampers minimize the structure resonant effects, increase power dissipation high blood pressure the displacement of structures. Other retrofit techniques include the usage of absorbers and baffles help make the building safe from an earthquake.
