Different types of terminologies associated with bridge structures

Given below, some of the general and short glossaries of terminologies found in a bridge construction.

Abutment: It is the portion of a structure that provides support to the end of a span or tolerates the thrust of an arch; frequently supports and sustains the approach embankment.

Anchor span: It is situated at the farthest end, it neutralizes the arm of span expanding in the opposite direction from a major point of support. Most of the time, it is connected with an abutment.

Anchorage: It is situated at the remotest ends, the section of a suspension bridge to which the cables are affixed.

Aqueduct: It stands for a pipe or channel that is open or encircled. It carries water. It is also utilized as the portion of a canal to transmit boats.

Arch: It belongs to a curved structure that provides support to beam a vertical load primarily by axial compression.

Arch barrel: It is the inside surface of an arch expanding the entire width of the structure.

Arch ring: It belong to an exterior course of stone that develops the arch. It is formed with a series of voussoirs. An archivolt is an arch ring having decorating moldings.

Ballustrade: It stands for a decorative railing, that is specifically built up with concrete or stone, along with the top and bottom rail and the vertical supports known as ballusters. It also contains larger vertical supports known as stanchions.

Baltimore truss: It belongs to a subdivided Pratt truss usually built up for the Baltimore and Ohio Railroad. It contains angled end posts and a top chord that is straight and horizontal.

Bascule Bridge: A bascule bridge means a movable span (leaf) that revolves on a horizontal hinged axis (trunnion) to hoist one end in vertical direction. A big counterweight is applied to offset to weight of the raised leaf. There is a single raising leaf or two which assemble in the center when closed.

Beam: It stands for a horizontal structure member that provides support to bear vertical loads by countering bending. A girder belongs to a larger beam, specifically when developed with several plates. The trusses are used to form deeper, longer members.

Bearing: It is a tool that is situated at the ends of beams and arranged on top of a pier or abutment. The ends of the beam are hinged on the bearing.
