Introduction of Rubber Bearing for Bridge:
The Rubber Bearing for Bridge also known as elastomeric bearings, are a critical component in modern bridge design. They are placed between the bridge superstructure (the deck and supporting beams) and the substructure (the piers and abutments) to allow for controlled movement and flexibility.
Rubber Bearing for Bridge are often used in applications where the bridge is expected to experience significant thermal expansion, seismic activity, or other types of movement. The curved shape and rotational capacity make them well-suited to handle these demanding bridge loading conditions.

The bearing capacity of Rubber Bearing for Bridge depends on the following three situations:
(1) The rubber itself is crushed or cut;
(2) the compression deformation and shear deformation of rubber exceed the allowable use;
(3) When the support (concrete, steel plate or other) is pulled off by the outward reverse horizontal shear force of rubber or the contact surface of the support and rubber slips off each other.
Classification of Rubber Bearing for Bridges: round board type rectangular plate type
Scope of application: ordinary bridge rubber bearing is suitable for the span of less than 30 meters, small displacement of the bridge. Different plane shapes are suitable for different bridge spans, rectangular support for orthobridge; curved, diagonal and cylindrical piers.
As with any bridge bearing, proper sizing, installation, and maintenance of basin type rubber bearings is crucial to ensure the long-term integrity and safety of the overall bridge structure. Let me know if you need any clarification or have additional questions!

characteristics and features of Rubber Bearing for Bridge:
Curved/Concave Shape: The defining feature of basin-type bearings is the curved, concave shape of the rubber element. This curvature is typically spherical or cylindrical in nature.
Rotational Capacity: The curved design allows the bearing to pivot and rotate as the bridge deck moves, helping to accommodate changes in load direction and bridge deformation.
