Bridge bearings are the critical components that connect the bridge deck to the substructure, providing support and allowing for movement due to thermal expansion, contraction, and live loads. They play a vital role in ensuring the safety, durability, and lifespan of bridges.
Types of Bridge Bearings:
Bearing Type | Description | Advantages | Disadvantages |
---|---|---|---|
Elastomeric Bearings | Made of rubber compounds | High flexibility, low cost | Limited load capacity |
Steel Bearings | Consists of steel plates and rollers | High load capacity, long lifespan | Susceptible to corrosion |
Pot Bearings | Filled with rubber or PTFE | Excellent load distribution, seismic resistance | Complex design, higher cost |
Spherical Bearings | Allow for significant rotation and axial movement | High load capacity, low friction | Require specialized maintenance |
