Seismic damping technology has been used for years in order to protect structures from adverse effects of earthquake. Thus, it is important to study seismic damping technologies in order to use them effectively. The purpose of this paper is to broadly classify the dampers currently in popular use, and explain their functioning. Friction Dampers, Viscous Dampers, Visco-Elastic Dampers and Tuned Mass Dampers are the majorly used dampers in the market nowadays. Viscous Dampers are considered the most efficient type of dampers. The efficiencies of various dampers also differ from each other and thus can be used at various places based on requirements. On further studies, it was found that the efficiencies of dampers not only depend on their type but also on their location and orientation. Dynamic analysis is used for the assessment of effects of dampers on structures. There are two types of Dynamic Analysis methods – Response Spectrum Analysis and Time History Analysis
