Components of a typical Plate girder and their functions are discussed in this article. Initial design of main plate girder is generally based on experience or thumb rules such as those given below. Riveted steel plate girder bridges Literature Wojnowski, Daniel A. If large embankment fills are required in the approaches to the bridge, in order to comply with the minimum headroom clearance required, the half through bridge is more appropriate . Triangulated bracing as shown in Fig. The detailed design process to maximise girder efficiency satisfying strength, stability, stiffness, fatigue or dynamic criteria, as relevant, can be then carried out. / Kenner, Matthew T. (2002): Analysis of a hybrid plate girder bridge during erection: collapse of Tennessee Highway 69 bridge . In the deck-type bridge, a wood, steel or reinforced concrete bridge deck is supported on top of two or more plate girders, and may act compositely with them. A compact section can develop full plastic moment i.e. Spacing of piers between the abutments is dependent on the capacity of the selected plate girders. Based on these, the summation of load effects due to different load combinations for various load factors are obtained. Thus, lateral bracings are a system of cross frames and bracings located in the horizontal plane at the compression flange of the girder, in order to increase lateral stability. When non-compact sections are used the redistribution will not occur and hence plastic analysis is not applicable. Technology Madras. This Plate Girder Bridge kit can be made up to suit any length of span required and is therefor.. £6.16. In this case the restraint to lateral buckling of compression flange is achieved by a moment resisting U-frame consisting of floor beam and vertical stiffness, which are connected together with a moment resisting joint. This type of girder is usually used to make certain types of bridges, and the girders themselves are very often in the shape of an I-beam. Become VIP Member.

Usually, the large steel plates of desired thickness are cut into the flanges and webs from the plates in the desired length and shape. [2], Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Free shipping . This type of failure depends on the unrestrained length of compression flange, the geometry of cross section, moment gradient etc. Retail $52.48 SAVE 14% ! Loads that act transverse on the plate girders also cause the lateral bending and the major contribution is from wind loads. The sections can be connected longitudinally or laterally and offer a vast range of spans and road widths. What is the percentage of carbon in wrought Iron? Based on these, the summation of load effects due to different load combinations for various load factors are obtained. This form of bridge is most often used on railroads as the construction depth (distance between the underside of the vehicle, and the underside of the bridge) is much less. $14.44. Cuts easily with fine-tooth or chop saw. Measures 26.5" wide x 1.75" high x .25" thick. ADD TO CART. The concrete deck is recommended to be precast on the girder and the modular unit can be shipped by truck to the bridge site. The deck slab spans transversely between the longitudinal girders and cantilevers transversely outside the outer girders. One option is then the Network Rail ‘Standard Box Girder’. Stresses on the flanges near the centre of the span are greater than near the end of the span, so the top and bottom flange plates are frequently reinforced in the middle portion of the span. In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam.In some cases, the plate girders may be formed in a Z-shape rather than I-shape.
