Multi-girder bridges are one of the most common types of medium span composite bridge in the UK. As a consequence of its simplicity and repetitive nature, branching and merging are no longer something to. Specifically, the example illustrates the design of selected critical sections from an exterior girder at the strength, service and fatigue limit states. The first example is of multi-girder form, the second is of ladder-deck form. For example, a low clearance bridge over poor ground might use multiple main girders on a single broad pier, whereas a high level bridge of the same deck width and span over good ground might use twin main girders, with cross girders, on individual columns. 2 Inclusions 26 5.

As a consequence of its simplicity and repetitive nature, branching and merging are no longer something to. Based on these research findings, this paper proposes a set of design guidelines considering the strength of the FRP deck subjected to out-of-plane compression, out-of-plane shear, and bending; static and fatigue strengths of the deck-to-girder shear connector; and effective flange width of the bridge system. At last the effectiveness of this method is demonstrated by the design of steel cantilevers which are used to widen an existing bridge. From the comparison, the author comes out with a design example for both design method. 2 Box Girder Section for Long Span Bridges UUUsual Span Ranges:UU Box girders are suitable for longer span than plate girders and allow larger span-to-depth ratios.
