Expansion joints are prone to leak and allow the ingress of de-icing salts into the bridge deck and substructure. In general all bridges are made continuous over intermediate supports and decks under 60 metres long with skews not exceeding 30° are made integral with their abutments.
Designing Metal Roofs For Thermal Movement ::Building The fixed joint should provide enough fasteners with a cinch plate to resist the combined affects of gravity loads and expansion/contraction forces as shown in Anchorage at Eave. The cinch plate confines the panel material which helps to increase its bearing resistance against the fastener and compresses the sealant for a tight seal.

Expansion Joints - an overview ScienceDirect TopicsOften involved are metal expansion joints between equipment and condensers (or coolers) and large, low-pressure piping with little flexibility. Concrete shrinkage and creep also belong in this category. A 10-ft column shrinks 0.06 in. during the first 6 years. Creep during the first 2 years is three to four times the original static deflection.
Designed to span gaps between structural elements, expansion joints are necessary to absorb movement, accommodate shrinkage and creep effects and changes in temperature on reinforced concrete, pre-stressed concrete and steel structures, and particularly on bridge decks.
Expansion Joints RJ Watson, Inc. - Bridge & Structural Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures.They stop the bridge from bending out of place in extreme conditions, and also allow enough vertical movement to permit bearing replacement without the need
Floor Expansion Joint CoversFloor expansion joint systems. allow 6 way movement or 4 way movement, whilst the surface fixed products generally cover 2 directional movement. They are designed to do the job right while barely being noticed by featuring minimal sight lines and high load ratings,available in Stainless Steel, Aluminium, Brass and various shallow cover plate inserts, to complement most facets of architectural design,
