Box girders are usually considered for footbridges only for spans over about 30m, and most box girder footbridges adopt an all-steel configuration. The advantage in using an all-steel configuration is that the whole cross section, including parapets, can be fabricated at the works for delivery and erection in complete spans; the weight of such spans is modest and easily . Why Composite Box Girders? According to The Steel Construction Institute (SCI, 2004), box girder bridges and I-beam bridges require approximately the same weight of steel. However, it has been discovered that composite box girders can be optimized to make the best use of their advantages, which can lead to slightly less steel usage.applications in which the girders have been used in straight bridge applications to match adjacent prestressed concrete U-beams. In these cases, straight steel box girders are used in regions where the clear span requirements preclude the use of the concrete U-beams. 17. Key Words Steel, Box Girders, Trapezoidal, Torsional 18.
