High damping bearing pad is used in bridge and structure. It has high damping value which can effectively absorb seismic energy to reduce seismic response in the earthquake. As the lead core bearing pad, it belongs to the seismic isolation bearing. High damping bearing pad consists of special rubber with excellent damping attribute, sandwiched together with layers of steel.Feature
Features high vertical loading capacity, recovery ability and high damping ability.
Provides seismic isolation effect while earthquake happening.
Applied at the bridge and structure of different ranges of temperature.
The high damping rubber has excellent recovery properties.
Has better aging-resistant ability with the top quality rubber and steel.Working principle
The damping ratio of high damping rubber bearing can approach to 15% - 18%. The high damping rubber bearing has excellent seismic effect by producing large deformation and small rigidity during the earthquake, for the elastic stiffness relies on its deformation degree. When the deformation is small, the stiffness is large, otherwise, the deformation is large and the stiffness will be small. And the high damping rubber bearing utilizing this principle generates excellent seismic isolation function.
Application
High damping bearing pad is suit for bridges.
