Abstract: Passive energy dissipation technology is widely used to protect structures from seismic damage together with traditional aseismic measures. In this paper, the studies and applications of the new technique at home and abroad are reviewed, including the principles and characteristics; the energy dissipation technology; the behaviors and restoring forced models of some energy dissipaters. The performance, design methods and codes of structure systems with energy dissipaters are introduced. Then, some new idea...
