Abstract
This publication briefly reviews the various passive energy dissipation devices that have been proposed and developed for reducing the seismic response of structures. The effects of supplemental damping on the seismic response of single and multi-degree-of-freedom systems are discussed. The devices are grouped into two categories: passive damplers and tuned systems. The first includes friction, metallic, viscoelastic, and viscous dampers and the second tuned mass dampers, tuned liquid dampers, and tuned liquid column dampers. The devices in each category, their make up, method of operation, method of design (if available), advantages and disadvantages, and examples of their applications are presented.
