Elastomeric bridge bearings, also known as can bearings or elastomeric bearings, are a common type of modern bridge bearing. The term includes several different types of bearings, including bearing pads, bridge bearings, laminated elastomeric bearings and vibration isolators. ...... In the construction industry, these bearings are often referred to as "bridge bearing pads".
The purpose of elastomeric bearings is to support a bridge or other heavy structure so that the load moves slightly in the horizontal direction relative to the ground or foundation. Without such bearings, the bridge support may break or fracture during movement due to ground movement or thermal expansion and contraction. Resilient bearing pads compress under vertical loads and accommodate horizontal rotational and horizontal shear movements.
The internal structure of a resilient bearing consists of three layers: a lower "pan" made of steel, which sits on a foundation or base; a relatively thin resilient pad (rectangular or disk-shaped) that rests on the lower pan; and a steel plate set loosely on top of the resilient disk, on which the weight of the bridge rests. The bearings are usually produced as a unit ready for installation.
Resilient pads can be made of any of a variety of materials, including natural rubber, elastomer, PTFE, or synthetic rubber (e.g., neoprene).
Elastomeric bearing pads are the most economical solution for use in the construction of large span bridges and buildings.
Elastomeric bearings are often used in applications other than bridges, for example, to support buildings built on soil that may move slightly and cause concrete loads to crack in the absence of elastomeric bearings.
Excellent flexibility: Adapts to the rotation of the beam end.
Large shear deformation: Capable of meeting the horizontal displacement of the superstructure.
Sufficient vertical stiffness: Able to withstand vertical loads and external forces.
Excellent isolation effect.: Can reduce the live load and the impact of earthquake.
Wide range of application.:In addition to bridges, it can also be used for water conservancy projects and seismic facilities
