In this graduate thesis will be shown dimensioning of reinforced concrete pedestrian bridge, whose static system is simple beam. The location of the bridge is in the central part of Istria county, and the bridge is crossing the Istrian highway in municipality Cerovlje. The dimensions of the bridge are adapted to the situation in the field as well as traffic requirements. As there does not exist the possibility to acess the bridge by a vehicle, the service vehicle load is not taken into acount. Bridge is intended just for pedestrians, with its width of 2,40 m. The bridge has a ribbed slab cross section with a single rib. From the variable effects all loads are taken into account, except the earthquake since it is not critical for this type of construction and area. The main carrier leans on the abutment over the elastomeric bearings, through which the load is transferred to the ground. Elastomeric bearings are chosen based on the relevant load combination. All calculations related to the main bridge carrier are based on european regulations: - EN 1990 (2002) (English): Eurocode – Basis of structural design - EN 1991 (2002) (English): Eurocode 1: Actions on structures - EN 1992-2 (2005) (English): Eurocode 2: Design of concrete structures – Part 2: Concrete bridges All calculations related to abutement are based on: - Szavits-Nossan, A., Ivšić, T.: Novi Eurokod 7: geotehničko projektiranje, Zagreb, 2006. Suggestions are also given during the calculations, if changing geometry or material characteristics can contribute to better material utilization.
