EFFECT OF FRICTION DAMPER ON SEISMIC PERFORMANCE OF MULTISTOREYED FRAME STRUCTURE IN HIGH RISE BUILDING-A REVIEW

Abstract

An earthquake is a spontaneous event of shaking ground caused by the passage of seismic waves through earth’s rock. Over the centuries they have been responsible for millions of deaths and extensive damages to the property. Now-a-days high rise buildings have become a trend and, moreover, they have paved the way to world competition in constructing tall buildings to exhibit the symbol of power and technology possessed by its population. Structures are mainly subjected to various types of loading conditions such as earthquake, wind loads etc. For earthquake zone areas, the structures are designed considering seismic forces. The structure which are present in higher earthquake zone area are liable to get damaged or collapsed, hence to increase the safety of these structure few protective systems are in the form of seismic isolation system and supplementary energy dissipating device are used to stabilize the structures against the earthquake and wind forces. The mechanical devices are incorporated into the frames of the structure and absorb the energy from the earthquake reduces the drift as well as effect on
the critical components of the structures. From the literature study it is concluded that they include different types of dampers like metallic dampers, viscous dampers, viscoelastic dampers, friction dampers etc. however there have been few investigations for the combinations of dampers, its advantages are discussed and a detailed review is carried out. By using the mechanical dissipating devices, it has been found effective and their application form focus of the study.
