HDRB High Damping Rubber Bearings are used for the isolation of a superstructure from the sub-structure. During an earthquake, the isolation can reduce the impact by seismic energy acting on the structure. HDRB High Damping Rubber Bearings are similar to normal elastomeric bearings with laminated steel plates, but the elastomer material has a special composition that dissipates seismic energy by deformation and heat generation.
In regular conditions, HDRB High Damping Rubber Bearings act as normal structure bearings, which transfer loads, movement and rotation between superstructure and sub-structure, but when earthquake comes, they work on the principle of base isolation and limit the energy transferred from the ground to the structure.
1. Put vertical bearing capacity, horizontal restoring force and damping (energy absorbing) these three characteristics into one ;
2. The hysteretic characteristic (load-deformation curve)of the bearing is plumper and the energy consumption is significant;
3. Rubber formula improving and equivalent damping ratio can reach more than 12%;
4. Low maintenance and management costs (no need of other damping devices);
5. Residual deformation is minimal after earthquake and do not need replacement;
6. The surface of high damping bearing is covered with rubber protective layer, which can protect the inner rubber from ozone and ultraviolet rays, and has better aging resistance. And decrease amplitude of equivalent damping ratio is less than 2% in 50 years;
7.HDR high damping rubber has low temperature dependence.And it can be widely used in different climatic regions;
8.HDR high damping rubber has superior creep properties as natural rubber;
9. Environmental and non-pollution.
