Bridges are usually constrained against horizontal displacement by providing a fixed bearing at one support and movement bearings that permit linear displacement of their upper parts relative to their lower parts at other supports. Such displacements occur principally due to thermal expansion and contraction.
This publication provides guidance on the determination of design values of linear displacements for bridge movement bearings, for use in specifying the requirements for bearings designed and manufactured in accordance with EN 1337.
