Abstrakt:

Arcadis recently designed and completed two complex bridges using the concept of composite plates (see EN 1994-2, section 9). The first bridge using this method, the Saint Lazare Bridge, crosses the busiest railway network in the city of Paris. The bridge consists of a 125 m long steel box deck with a deck width of 17,5 m resting on V-shaped piers. The thickness of the concrete slab is 120 mm. The second bridge, currently under construction, is the viaduct of Guerville. This viaduct is a 360 m long concrete-steel composite bridge with two I-shaped girders linked together by floor beams. The design of the central part of the deck, which is governed by the central span length of 116,5 m, required a lighter and thinner slab than the typical reinforced concrete top slab. This led to the use of a composite plate, 160 mm thick for the 157 m central part of the bridge. This paper presents the general design of both bridges along with the specific methodologies and calculations used for the composite deck plate designs.
