BRIDGE SUPERSTRUCTURE

'Bridge Superstructure' deals with the behaviour of different types of bridge decks under different systems of loading. Mathematical modeling and the behaviour of different types of bridge decks are clearly explained. Solid slab, voided slab and skew slab bridge decks are detailed out for analysis and design. Box girder bridges is specially discussed for better understanding of its behaviour and its design. Special points relating to creep and shrinkage effects in continuous bridge decks are explained. Bridge bearings, expansion joints and appurtenances of different types are explained with respect to their place of use and their functions. A few methods of erection of bridge decks of simply supported spans or continuous spans are presented to give a good understanding of such possibilities.
