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 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.
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.
