Products Description

BAOLI HDR rubber bearing is composed of alternating laminations rubber layers and vulcanized steel plates (shims), bonded together to provide vertical rigidity and horizontal elasticity.

The vertical stiffness ensures that the isolator will support the weight of the structure, while the horizontal flexibility translates the destructive horizontal vibration into a gentle motion.

Since the steel plates are completely embedded in the elastic material, they are sealed and thus prevent corrosion. The devices are manufactured with rubber vulcanized to the top and bottom connection plates. The bearings can also be supplied with additional anchor plates, allowing easier replacement of device in case of maintenance needs.

Design principle

The working principle of BAOLI high damping rubber bearing is the isolation of the base and the transfer of energy from the ground to the structure during an earthquake. Rubber and steel laminate supports are designed to support the weight of the structure and provide flexibility after yielding. After the earthquake, the rubber provides isolation and re-centring of the bearings, while reaching higher damping of up to 16%.
