Structure description
At this location the motorway route follows a horizontal curve of 2,655-metre (8,711 ft) radius. Transversal grade of the deck is constant and equal to 2.5%, while elevation grade of the eastern part (closer to Bosiljevo 2) of the viaduct is constant at 5.2505% while its western part (closer to Vrbovsko) follows a concave vertical curve of 12,000-metre (39,000 ft) radius. The viaduct is a beam structure supporting the deck slab across 18 spans: 38.8 m (127 ft) + 16 x 39.9 m (131 ft) + 38.8 m (127 ft).[1][4][6]
Superstructure of the viaduct consists of prestressed prefabricated girders executed as freely supported beams. As their longitudinal joints were concreted atop the viaduct piers they comprise continuous girders, made composite with the deck slab using standard reinforcing steel. Cross-section of the viaduct consists of two parallel structures, and each structure comprises five longitudinal girders whose axes are placed 2.6 metres (8 ft 6 in) apart. The deck slab consists of 7 centimetres (2.8 in) thick prefabricated omnia slabs and a 18-centimetre (7.1 in) thick monolithic section completing the deck. Piers of the viaduct comprise a 5-metre (16 ft) by 3.2-metre (10 ft) box section with 30-centimetre (12 in) thick walls. Height of the piers ranges from 20 metres (66 ft) to 55 metres (180 ft), carrying the route across a natural dry valley.[1][4]
