Box Girder Bridge is a bridge where the key beams consist of girders shaped like a hollow box. The deck may consist of 3 girders spaced at 2, 45 m. centres. However, the bulk of this long viaduct consists of longer spans each of which has been strengthened by adding a small degree of upward curvature to the upper horizontals. The transverse location is described by an offset from either the Bridge Line or the Alignment. 0000005487 00000 n girder definition: 1. a long, thick piece of metal or concrete, etc. 0000004356 00000 n It … LRFD Design Example for Steel Girder Superstructure Bridge SI Units Early iron structures using a Town-type lattice replicated this appearance, leading to the instantly recognisable lattice-work shown in the bridges in Part A of this list.

The span of the girders is 23.35m(c/c brg), and the overall girder length is 24.0m. The term "lattice girder", is used in the UK and "lattice truss" is more widely used in the USA. 0000005012 00000 n Girder bridges are the simplest bridge type in structure and consist of steel beams shaped to an I-section or box section, called a plate girder bridge or a box girder bridge, respectively. 2. Adil, M., Adnan, M., Hueste, M., and Keating, P. (2007). In later forms, various developments took place: for example, the lattice became less dense and each individual diagonal thus much more substantial; vertical members were introduced; and eventually both diagonal and vertical members achieved cross-sectional dimensions comparable to those of the main top and bottom components, thus forming what is more commonly known as a truss. Examining the cross section of the I-Beam speaks for its so name. Such a member is better described as a "laced strut", and such members frequently form a significant part of a lattice girder. Trussed Girder Bridges. The remaining portions are regular beam bridges. 0000010591 00000 n Type # 1. The following examples illustrate how girder spacing is defined. 0000170065 00000 n trailer 0000147644 00000 n Attached is a model file and a PDF which outlines the procedure for modeling a concrete box-girder bridge, a steel-girder bridge, and a cable-stayed bridge. (Note that some bridges, for example the New Clyde Viaduct (or Second Caledonian Bridge) in Glasgow, appear to be of lattice construction whereas in fact the latticing is used solely for the protective parapet.). In its simplest form, a log across a creek is an example of a girder bridge; the two most common girders are I-beam girders and box-girders used in steel girder bridges. 0000148523 00000 n The design example and commentary are intended to serve as a guide to aid bridge design engineers with the implementation This example illustrates New Mexico Department of Transportation (NMDOT) design procedures for a three-span prestressed concrete girder bridge.

Bridge Design Group. Tied-arch bridge (also called bowstring-arch or bowstring-girder bridge) is a type of bridge that has an arch rib on each side of the roadway (deck), and one tie beam on each arches, that support deck. Girder bridges are comprised of deck slabs, on which vehicles and people pass, and of main girders supporting the deck slabs. This list is intended to help identify a particular early form of lattice girder bridge which was popular with bridge engineers particularly in the United Kingdom in the latter half of the 19th century. 0 The offset can be measured to a specific girder or to the center of the girder spacing. <]/Prev 568447/XRefStm 2329>> 0000004912 00000 n Attachments. 118. startxref 0000146236 00000 n Learn more.
