Rehabilitation of the bridge over the river Ribnica

Abstract

The paper presents a rehabilitation project of the bridge over the river Ribnica, based on on-site inspection and available technical documentation on the condition of the bridge. The existing bridge is a road, reinforced concrete with main steel girders IPE 180. The existing girder bridge has a span of 2 m x 6,5 m. Two variant solutions for the rehabilitation of the existing bridge are analyzed. The first solution included the removal of the existing reinforced concrete plate and the production of a new reinforced concrete plate, with the rehabilitation of the steel girders in accordance with the new load impacts. The second solution includes the removal of the existing reinforced concrete plate, the dismantling of the existing steel profiles and the production of a new reinforced concrete plate. The terms of reference required that the effects on the bridge be considered for the V300 vehicle. In addition to the road construction, two footpaths were designed. The static calculation was done in the Radimpex Tower 8.4 programme.
