The lead rubber bearing has same mechanical properties with laminated rubber bearing. Besides, it has high damping property.
As we all know, the laminated rubber bearing has large displacement deformation in horizontal direction.
In the earthquake, this structure can separate top and bottom structure vibration, enlarge self vibration cycle and reduce seismic force. Besides, the lead core will be squeezed and yielded during the shear process to dissipate Seismic force.
After the earthquake, the lead rubber bearing can help building restore the normal position through dynamic recovery and recrystallization of lead core and shear strain of laminated rubber bearing.
