High damping rubber (HDR) bearing-HDRBs that uses high damping rubber; where the rubber material itself demonstrates spring and damping capability. Generally, separate damper is not required; good for space-constraint installation.
Since its hysteresis curves are relatively smooth, seismic isolation effect can also be expected for in-building precision equipments, etc., rather than for buildings only. Rubber material has two different kinds of elastic modulus(refer red as E0.4, X0.6R), it’s also applicable to light column load.
High damping rubber (HDR) bearings are made of alternating layers of rubber and steel plates, and they are designed to isolate a structure from ground movements during an earthquake. The rubber’s spring and damping properties, along with the steel plates’ vertical stiffness, help to dissipate seismic energy and limit the amount of energy that acts on the structure.
Benefits
HDRBs are cost-effective, maintenance-free, and can be designed to withstand significant earthquakes without major damage. They can also be used to isolate precision equipment within a building.
Features
HDRBs have a strong bond between the rubber and steel, and the rubber is specially formulated to provide the required damping. They can operate in temperatures ranging from -40°C to +60°C.
