The bearing is composed of several layers of rubber sheet and thin steel plate superimposed by pressure vulcanization, which has enough vertical stiffness to meet the vertical load, and has good elasticity to adapt to the rotation of the beam end. It has large shear deformation to meet the water of the superstructure horizontal displacement, and has a good seismic effect, can reduce the dynamic load on the upper structure and pier impact.
Features of rubber bridge bearing:
(1) Quality materials including natural rubber, neoprene complying with AASHTO standards.
(2) Allow for expansions and contractions of precast steel structure of bridges.
(3) Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.
(4) Vibration, sounds and shocks isolation.
(5) Avoid excessive load eccentricity and edge compression.
(6) Simple but robust structure.
(7) Lower price than laminated elastomeric bearing.
(8) High cost effectiveness.
(9) Minimal maintenance is needed.

The elastomeric rubber bearings are widely used in bridges, buildings, roads, railways, and other engineering projects. They primarily serve to transmit the load from the superstructure and alleviate displacement and deformation caused by temperature changes, concrete shrinkage, and uneven foundation settlement. Due to their excellent elasticity, seismic performance, and durability, plate rubber bearings play a crucial role in various engineering projects, especially in seismic design, where they effectively reduce the damage to structures caused by earthquakes.
