Product Details
elastomeric seismic isolation bearing in bridges
High-damping rubber bearings are made by adding various compounding agents to natural rubber, which can improve the damping performance of rubber. The bearings made of rubber with this damping effect are called high-damping rubber isolation bearings. High-damping rubber bearing, due to the use of high-damping rubber, has stable support, elastic reset and damping functions, can absorb seismic energy during earthquakes, reduce earthquake impact, and can be used alone as an isolation device.
Product features
1. Trinity of vertical bearing capacity, horizontal recovery force, damping (energy absorption);
2. The hysteretic characteristics of the bearing (load-deformation curve) are full and the energy consumption is significant;
3. The rubber formula is improved, and the equivalent damping ratio can reach more than 12%;
4. Low maintenance management cost (no other damping device required);
5. The residual deformation after the earthquake is very small, no need to replace;
6. The surface of the high damping bearing is covered with a rubber protective layer to protect the internal rubber from ozone and ultraviolet rays, and has better aging resistance. The equivalent damping ratio in 50 years is less than 2%;
7. HDR high damping rubber has low temperature dependence and is widely used in different climate regions;
8. HDR high damping rubber has superior creep performance like natural rubber;
9. Environmental protection and no pollution.
