Large bridges will need to have their sizes adjusted upwards in a proportional method, e.g. broad ladder decks would require proportionally wider and thicker flanges. The design charts cowl each ladder deck and multi-girder forms of building and account for the variations between internal and outer girders in multi-girder bridges. The charts are totally according to Eurocode loading, as carried out by the National Annex to BS EN , and design resistances given in accordance with the related Parts of Eurocode 3 and Eurocode four. For ladder decks, the spacing of the main girder is dictated by the chosen length of cantilever, with a most spacing of about 18m. Cross girders are generally spaced at between three.5m and 3.8m however the spacing will have to be adjusted at the ends and intermediate supports of skew bridges. Steel cantilevers can be added to support longer cantilevers on ladder decks if required … Read More
