Product Description
Building Construction Isolation Lead Core Rubber Bearing
Building Construction Isolation Lead Core Rubber Bearing
Lead Rubber Bearing – Excellent in Absorb Energy Dissipation and Seismic Isolation
    Lead rubber bearing, also called lead core rubber bearing, LNR rubber bearing, has similar structure with high damping rubber bearing. It is an important component of seismic isolation bearing. It is composed of laminated rubber bearing and lead core. The lead core can not only bear the heavy load and horizontal force, but also absorb energy through plastic deformation of hysteresis damping.
    Lead rubber bearing can be divided into round and rectangular shapes for different application. Additional, the lead core quantity can be single or multiple to supply maximum flexibility in the bridges or building.
Working principle
Building Construction Isolation Lead Core Rubber Bearing
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.

Performance comparison between lead rubber bearings and ordinary rubber bearings
There are significant differences in damping performance between lead rubber bearings and ordinary rubber bearings. The damping coefficient of the former typically exceeds 15%, while that of the latter is generally below 5%. This excellent damping property allows lead rubber bearings to effectively extend the structural period of bridges and significantly reduce the acceleration response of the superstructure. Under seismic action, lead rubber bearings can significantly improve the stress state of the structure during the earthquake due to their unique mechanical properties, making them particularly suitable for being set in areas with a seismic intensity of 8 degrees or higher.
