High Damping Rubber Bearing(HDR)

- - 1

High Damping Rubber (HDR) Bearing – HDRBs use high damping rubber. This rubber acts as both a spring and a damper. Generally, a separate damper is not required; it is good for space-constrained installation. Seismic isolation makes buildings safer and protects sensitive equipment. The smooth hysteresis curves show this clearly. Rubber has two types of elastic modulus, noted as E0.4 and X0.6R. It works well for light column loads, too.

High damping rubber (HDR) bearings consist of layers of rubber and steel plates. They help isolate structures from ground movements during earthquakes. The rubber’s spring and damping help absorb seismic energy. The vertical stiffness of the steel plates also limits energy to 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.
