Product Description

Product Description

High damping rubber bearing, also called HDR bearing pad, is one of seismic isolation bearing. It has excellent seismic isolation performance to effectively reduce the bridge damage caused by earthquake.

HDR bearing pad is composed of specialized designed rubber with high damping performance, sandwiched together with steel plate layer. When installing, the high damping rubber bearing is commonly used with top and bottom steel plate and connection accessories.

Working principle

During earthquake, the vibration from various directions will impact fixed base building and results in deformation and building or bridge damages. The high damping bearing pad is improved through high damping material, which the damping ratio can approach to 15% to 18%.

When the earthquake comes, the high damping rubber bearing will increase the horizontal displacement through rubber shear deformation and reduce friction coefficient. The large displacement can weaken the vibration from all direction and reduce the damage of building and bridges.
 

	Damping ratio
HDR (I) bearing rubber	15%
HDR (II) bearing rubber	12%
LNR bearing rubber	10%
