An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections. Expansion joints can be non-metallic or metallic (often called bellows type). Non-metallic can be a single ply of rubberized material or a composite made of multiple layers of heat and erosion resistant flexible ...
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.
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.
mageba was founded in 1963 in Bulach, Switzerland. By 1969 the company was designing and manufacturing a variety of bridge bearings and expansion joints, [4] and had heavy duty testing facilities in operation. [5] In 2004 the company merged with Proceq. [6] The resulting company continued to design and manufacture bridge bearings and expansion ...

“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."
An expansion joint which allowed for a maximum thermal movement of ± 835 millimetres (32.9 in) was also provided and located inside the approach span. The bridge parapets are of a special design by Hong Kong standards, comprising high-tension steel strands anchored on metal posts. [25]
A slide plate is a linear bearing that may be part of the expansion joints of bridges, high temperature horizontal ducts of water-tube boilers and other mechanical or structural engineering applications. In each case one plate is fixed and the other slides on top as expansion or contraction occurs.
