world class HDR bridge bearing rubber damping bearing

1)up to 16% damping,high damping 2)no damage for high intensity earthquake 3)used in building and bridge 4)rubber products

high damping rubber bearings:HDRB isolators consist of alternate layers of rubber and vulcanised reinforcement steel plates of limited thickness. They allow isolation of the structure by a proper selection of the horizontal stiffness and they can dissipate energy up to 16% damping due to high damping rubber compound.

HDRB isolators fulfil the following requirements: Transmit the vertical loads due to permanent and accidental effects; Capacity to support horizontal loads due to service load conditions with very low displacements Capacity of isolate the structure by shifting the fundamental vibration period to an optimal and safe level Capacity to dissipate energy to reduce the horizontal displacement of the isolated structure with respect to the ground
