Product Description
High Damping Rubber Bearing – Fixed and Sliding Types for Large Displacement
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.
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.
Joint structure
*The HDR (Ⅰ) rubber bearing. It is designed with top and bottom embedded steel plate. And the rubber bearing is connected with pier and beam by sleeve. The top and bottom loading plate is connected with sleeve by anchor bolt. The top and bottom embedded steel plate is connected with sleeve by welding.
*HDR (Ⅱ) rubber bearing. It is designed with top embedded steel plate and without bottom embedded steel plate. The bottom loading bearing is connected with sleeves with anchor bolts. The top embedded steel plate is connected with top loading plate with shear tenon. And the top embedded steel plate is connected with sleeve by welding.
HDR (Ⅰ) rubber bearing.
HDR (Ⅱ) rubber bearing.
Feature
*Excellent horizontal displacement. absorb shock energy effecively.
*Excellent reset structure. there is no residual displacement.
*High damping material. 10% to 18% damping capacity for shock absorption.
*Wide range structure for different environments and displacement requirements.
*Economical and high performance for lower total construction budget.
*Easy installation and replacement for lower maintenance cost.
*Excellent reset structure. there is no residual displacement.

Damping structure
*Fixed type (HDR rubber bearing). The high damping rubber has excellent horizontal shear performance to bear the horizontal force. It can absorb vibration through large displacement in horizontal direction and hysteretic energy.
*Rectangular HDR rubber bearing.
*Round HDR rubber bearing.
*Sliding type (LNR rubber bearing). The displacement is achieved by sliding friction. The top stainless steel plate and PTFE sliding plate can reduce friction coefficient and achieve large displacement for shock absorption.
*Round HDR rubber bearing.
