DESIGN OF COMPOSITE STEEL AND REINFORCED CONCRETE BOX GIRDER ROAD BRIDGES WITH PARTIALLY PRESTRESSED DECK SLABS

Two similar 3-span continuous bridges over the Southern Expressway in the city of Wollongong, NSW, designed for the dmr in 1970 have concrete deck slabs forming the top flanges of steel box girders. The slabs are partially prestressed longitudinally to produce compression over the piers, where otherwise they would have been in tension. The selection of the type of superstructure was influenced by the suitability of steel as a structural material in tension and the proximity of steelworks as a politic factor, besides the relative cost of steel and concrete. The concrete deck prestressing, erection procedures and effect of creep of the elastomeric bearings at the abutments are mentioned (A). (TRRL)
