Elastomeric Bridge Bearings

Structures are subjected to imperceptible displacements and rotations that have to be accommodated to protect the structure and
surrounding infrastructure. The most common causes of movement being:
Temperature changes
Traffic movement and braking
Wind
Shrinkage and creep
Foundation movement
Post stressing
The function of the bearing is to safely accommodate the various movements and rotations as well as supporting the weight of the
structure and to transmit the load through to the structures foundation.
Elastomeric Bearings are designed to accommodate three types of movement:


1. Vertical
2. Shear
3. Rotation
