What are the different types of bridge bearings

The main types of bridge bearings include oil felt or flat plate bearings, plate rubber bearings, spherical bearings, steel bearings, and special bearings. These types of supports have their own characteristics and are suitable for different bridge structures and requirements.

Oil felt or flat support: This type of support has a simple structure, low cost, and is suitable for bridges with small loads.

Plate type rubber bearings: made of multiple layers of rubber sheets and thin steel plates vulcanized, suitable for bridges with spans less than 30 meters and small displacements.

Spherical bearings: capable of adapting to large displacements and angles, suitable for large-span bridges.

Steel bearings: With high bearing capacity and stiffness, they are suitable for bridges with heavy loads.

Special bearings: designed according to special requirements such as seismic resistance, corrosion resistance, etc., suitable for bridges in specific environments or applications.

These types of supports play an important role in bridge engineering, effectively transmitting and dispersing the loads borne by the upper structure of the bridge, while adapting to the deformation requirements of the bridge, ensuring the safety and stability of the bridge.
