Abstract: Conventional methods of seismic reintegration with concrete shear walls or rigid steel bracing are considered expensive and tedious. The schedule and tight budget meant that these conventional options are not feasible. The principle of friction brake is most widely adopted available method to extract kinetic energy from a moving body. It is the most reliable, effective and economical mean to dissipate energy. This principle of friction brake has inspired the development of friction dampers. Similar to automobiles, the motion of vibrating building can be slowed down by dissipating energy in friction. Several types of friction dampers have been developed. For frame buildings, these are available for tension cross bracing, single diagonal bracing, chevron bracing, and friction connectors at expansion joints to avoid pounding. The paper gives the study of different literature investigation taken on friction damper
