Pin and hanger assembly. A pin and hanger assembly is used to connect two plate girders of a bridge.These assemblies are used to provide an expansion joint in the bridge. One beam (the anchor span) is set on a pier with a short section cantilevered out toward the next pier.
A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.
A breather switch, expansion joint, or adjustment switch is an intentional gap in railway tracks to allow for thermal expansion in long sections of otherwise unbroken rail. . They are placed between very long sections of continuous welded rail or at the transition from continuous welded rail to jointed track, and commonly in the vicinity of bridges, viaducts and tunnels where the ...
The omission of the expansion joint removes a pathway for the penetration of chloride-bearing road salts to the bridge's sub-structure. In the United Kingdom there is a presumption that most new short to medium length bridges will be of the integral type. [citation needed] An early example of an integral bridge is masonry arch bridge.
The bridge design submitted by the winning team is an efficient solution that utilizes a shallow superstructure and a 350' long-span design to minimize the number of piers, provide a sleeker ...
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
An expansion bearing on the Queen Elizabeth II Metro Bridge. A bridge bearing is a component of a bridge which typically provides a resting surface between bridge piers and the bridge deck . The purpose of a bearing is to allow controlled movement and thereby reduce the stresses involved.
“Whenever a design code is written, decisions have to be made about what the most extreme conditions are,” he said. Maryland Gov. Wes Moore said the bridge was "fully up to code."
