Damping capacity is strong and durability, corrosion resistance, anti-fatigue performance are good, the big advantages such as low with maintenance cost of operating temperature range.
It is the root that structure generates vibration because the reasons such as earthquake are transferred to the external energy of building structure, so damper
Energy consumption property will be the key for the dynamic respons for reducing structure, and the damper researched and developed at present is easy because of energy dissipation behavior not
Sufficient and structure is uncoordinated and loses constraint and anti-buckling effect, its energy dissipation capacity is caused to be greatly reduced.Therefore, some dampers
Manufacturing process, there is still a need for be further improved for energy-dissipating property etc..
