STUDY OF POUNDING MITIGATION TECHNIQUE BY USE OF ENERGY DISSIPATION DIVICES

In this paper the pounding mitigation techniques using dampers are studied in detail. The dampers such as viscous damper, viscoelastic damper, friction damper and tunned mass dampers can be used as a energy dissipation devices, however viscous damper and viscoelastic dampers are most commonly used. Viscous material is material in which strain developed over a period of time and material does not go to its original shape after stress is removed. Viscoelastic material is a material in which total strain developed has two components namely viscous and elastic. In this case the response of viscous and viscoelastic dampers are studied with respect pounding of building.
