Seismic forces are induced on the structure present in earthquake prone areas. These are induced due to the movement
of tectonic plates. Multi-storey buildings are those that have more than two stories, hence undergo large amount of deflection
due to their slender structure. Due to the deflection caused by the ground accelerations during earthquakes, the structure is
unstable and the structure undergoes damage which is not safe. Passive energy dissipation devices are gaining significance in
design of earthquake resistant structures because of their effective performance in controlling seismic effects on structures
during earthquake. Friction dampers and fluid viscous damper are passive energy dissipating devices which are used widely as
seismic control devices.
