Viaduct Designs on the Section of the Pan-European Corridor X in South Serbia

On the planned section of the motorway E–75, a viaduct design has been developed to connect the deep valley and Koznicka River. The right and the left lane of the motorway divert in the viaduct area, because the motorway leads into two separate tunnel tubes, right after the bridges. According to the layout solution, a design has been prepared for a 6 field viaduct, bridged over by previously prestressed precast girders with a span L = 25.40 m and which have continuity over intermediate piers. Within the scope of a cross section, four precast girders with 'I' cross-section, with height of h = 1.70 m and mutual spacing λ = 3.00 m, have been anticipated. Reinforced concrete pavement slab is cast over the girders. Reinforced concrete cross girders above intermediate piers are being cast together with a slab, thus providing continuity. The impact calculation within the load girders, caused by their own weight, fresh concrete mass of cross girders and the pavement slab, has been carried out within the first phase. For this loading phase calculation and impact control have been carried out within the bearing beams and intermediate piers for cases of symmetrical and asymmetrical load disposition. After the executed continuation of the span structure and formation of a continuous panel structure with intermediate piers, calculations have been carried out for the impact of primary and additional constant load, traffic volume, additional effects and exceptional effects, using the SOFISTIK software package.
