Performs vertical force transmission and rotational functions through reinforced special rubber pads that dissipate seismic energy, control displacement and transmit remaining horizontal forces to piers through special rubber properties
Accommodates horizontal displacement through shear deformation of rubber pads
Main material: special rubber
overview
A mixture that can absorb vibration energy is added when compounding rubber, and the rubber intermolecular friction damping and the viscous damping element due to the viscous material existing between the rubber molecules combine to absorb the energy.
Since the rubber itself has a mechanism that can absorb energy, the resilience characteristics after an earthquake are superior to lead seismic isolation tables.
