Abstract:
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.
