high damping rubber bearing(isolation earthquake bearing) we usually call Base Isolation System, high stability aseismic bearing, Earthquake Absorbing Damper Bearing, Building shock isolation rubber bearing, Earthquake Isolation Bearing etc.
1. Application of High damping rubber bearing made in China.
High damping rubber bearings(HDRB) are used in bridges and structures. The principle is different from mass- Spring system with single degree of freedom of EBP, and they can achieve transverse and vertical damping effect on the basis of two-wad, especially applicable to the basic vibration reducing system. For the regions which have special requirements on the environment. Such as residential areas, high-tech industrial parks, nature reserves and etc, the bearings can be widely used.
2. Description of High damping rubber bearing made in China
High Damping Rubber Bearings (HDRB) are large laminated elastomeric bearings which are ideal for seismic isolation with one device - supporting the structure, for base isolation, providing elastic restoring force and required amount of damping up to a maximum of 10-15% of critical. Moderate damping is achieved with this type of bearing.
3. Features of High damping rubber bearing made in China
HDRB isolation bearings are vertically stiff, capable of supporting vertical gravity loads, while being laterally flexible, capable of allowing large horizontal displacements. In effect, the ground is allowed to move back and forth under a base isolated during an earthquake, while leaving the building to remain "stationary. "
