Product Description

Product Description

LRB Lead Rubber bearing for Bridge seismic Isolation
Base Isolation LRB lead rubber bearings work on the principle of base isolation and limits the energy transferred from the ground to the structure in the event of an earthquake. Base Isolation Lead Rubber Bearings (LRB) consists of a laminated rubber and steel bearing with steel flange plates for mounting to the structure. All isolators have an energy dissipating lead core. 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.

LRB Lead Rubber bearing for Bridge seismic Isolation 
Excellent durability of rubber: LRB applies special additives for the rubber, yielding stable mechanic properties: tensile strength, ultimate elongation and adhesive strength.

Stable Bilinear behavior:LRB demonstrates stable bilinear behavior, resulting in a more accurate structural analysis, since bilinear simulation accurately simulates real-world scenarios.

+ Vertical load applied:5 tonf~2000 tonf.
+ Easy design to accommodate different structural properties.
+ Easy installation, low cost maintenance.
+ Effectively reduce the ground acceleration, long durability.
