Abstract

This paper presents repair design for bridge over the Resnica River in Koceljeva municipality (Serbia). As part of repair strategy, visual inspection of damages and condition diagnostics of structural elements were conducted. In addition, the bridge was tested with trial static loads. Structural system of the existing bridge is constructed as a double overhanging slab with inner span of app. 4,5 m and cantilevers of approx. 1,0 m each. Main span is supported by transverse beams with variable cross-section which are constructed on top of the abutments. As part of repair design, the bridge was widened on each side with 1.0 m wide footways. Since the original structural design documents are missing, control calculations were conducted with Tower Radimpex Software (according to national codes). This analysis was followed by more sophisticated numerical modelling and analysis according to Eurocode with Abaqus Software.
