Types of isolation bearing according to the degree of damping points
1.Lead rubber bearings
LRB rubber bearing, applied to building and bridge constructions, is a practical and cost-effective choice for seismic isolation. It is composed of laminated elastomeric bearing pad, with lead in
the center of bearing. This series of bearing is suitable for 8 degrees and the earthquake intensity area
of highway and municipal bridge.
2.High damping rubber bearings
Its structure is the same as ordinary laminated rubber bearings, High Damping Rubber Bearing is
improved through rubber formula, so that the rubber material damping is increased, so that the bearing's
damping ratio can reach 15-18%. This series of bearing is suitable for 9 degrees earthquak intensity
area of highway and municipal bridge.

Special Features of lead rubber bearing
(1) Strong Points
(2)Property of Lead as a Suitable Material for Earthquake Absorbing Work
(3)The Economic Design
(4)The More Excellent Safety
(5)Easy Installation

Function of lead rubber bearing
The rubber in the isolator acts as a spring. It is very soft laterally but very stiff vertically. The high vertical stiffness is achieved by having thin layers of rubber reinforced by steel shims. These two characteristics allow the isolator to move laterally with relatively low stiffness yet carry significant axial load due to their high vertical stiffness. The lead core provides damping by deforming plastically when the isolator moves laterally in an earthquake.
