| Abstract: |
The viaduct over the Genil River is a road bridge built as part of the Albolote-Santa Fe Segment (Granada) of the A44 Highway in Sierra Nevada. It consists of three spans 15 m + 80 m + 15 m long making a total length of 110 m. Three concrete tied arches are placed in the main span. The central arch, with a sag of 16,6 m, remains in a vertical position while the lateral arches at both sides are sloped towards the inside of the deck, 10 degrees with respect to the vertical. The superstructure is 41,20 m wide and consists of three longitudinal prestressed concrete beams. The exterior beams consist of a solid section 1,30 m deep while the interior beam consists of a box girder 1,50 m deep. The reinforced concrete slab is supported by transversal prestressed girders. The viaduct is placed in high risk seismic zone, being the acceleration 0,33 g. |
