This report presents the design and results of the strengthening of a double trough concrete railway bridge in Haparanda, Sweden. The objective was to find a strengthening solution, which provides a sufficient shear capacity in the transversal direction for the bridge slab when the allowed axle loads on the railway are increased from 25 to 30 ton.Unbonded post-tensioning was chosen as the strengthening method and the design was performed according to the design criteria of Eurocode. The results indicate increased interaction between the two troughs, as well as an increased capacity. All reinforcement strains caused by a train with 21.5 ton axle loads were counteracted by the compressive action obtained by eight prestressing bars, stressed w...
