seismic applications; passive energy dissipation


This publication briefly reviews the various passive energy dissipation devices that have been proposed and developed for reducing the seismic response of structures. Most of the devices are effective in providing structures with additional damping and strength and in reducing seismic response. 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 dampers 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. Further research is needed to provide standardized performance evaluation procedures and testing for small and full-scale specimens.
