Inelastic Aseismatic Analysis Of New Energy Dissipation Braced Frame

Passive energy dissipation technology is a new structure design method developing in recent year. It is more safe, economic and reasonable than traditional structure design method, especially suitable for using in cases where earthquakes are unpredictable. The energy dissipation system is formed by adding some energy dissipaters into the structure that will dissipate most vibration energy from vibration sources, then ensure the structure to be safe in earthquake or to satisfy the using requirement in wind. A variety of energy dissipation systems have been developed in the past two decades, such as friction dampers, metallic dampers, visco-elastic dampers and viscous dampers.In this paper, the studies and application of the new technique at home and abroad are reviewed, including the principles and characteristics; the behaviors and restoring models of some energy dissipaters. Energy dissipation braced frames will be used to design a power plant structure, through comparative inelastic aseismatic analysis for four frame structures; the excellent aseismatic behaviors of the energy dissipation braced frame are obtained.
