Seismic response control for high-rise buildings using energy-dissipation devices
Application of energy dissipation devices is reasonable and cost effective to maintain main structural members in elastic state for high-rise buildings. This paper discusses required energy dissipation performance for the long-period ground motion on M7 class earthquake and the ability of JFE hysteretic energy dissipation devices. Some important points to keep in mind in the structural design of vibration damping structures applied to recent high-rise buildings are described, the structural performance of the vibration dampers developed at JFE Steel are outlined. The performance of vibration dampers installed in high-rise buildings against long-period earthquake motions is evaluated. Some examples of the application of JFE vibration dampers to high-rise buildings are presented. Many of JFE's vibration dampers are adopted in RC high-rise buildings, as well as in steel-frame high-rise buildings. And the adoption of JFE vibration dampers in production facilities other than high-rise buildings is also increasing. Many predictions of damage due to massive earthquakes, such as inland earthquakes in the Tokyo Metropolitan Area, have been disclosed to the public in recent years. This is one of the reasons why seismic dampers are expected to become more widespread in various building applications in the years to come. JFE will take part in this trend by developing new vibration damping techniques to meet social needs in the future, as well.
