What is Seismic Retrofit

Seismic retrofit is normally performed in seismic zones for the prevention of damage by earthquake seismic waves. Several techniques are used including use of trusses, dampers, and absorbers. Seismic retrofit is a field of construction engineering that focuses on the modification of the existing structures to enhance their capability to resist earthquakes. Seismic retrofitting is achieved by the inclusion of structural improvements that may prevent the building, people, and the equipment from the damage by seismic waves. In seismic zones retrofitting may be essential for the bridges, overpasses, tunnels, and buildings, while the new construction would require compliance to seismic standards.
