INVESTIGATION AND STRENGTHENING STUDY OF TWENTY DAMAGED BRIDGES: A BELGIUM CASE HISTORY
At the present time, the Walloon Region of Belgium is very concerned about the maintenance and repair of twenty bridges of similar design built during the fifties. These prestressed bridges are particular because they are based on pairs of inclined and double-hinged piers, the inner ones being compressed and the outer ones being prestressed by wire tendons. After the collapse in 1992 of such a bridge in the Flemish part of the country, a complete investigation programme was performed on the twenty similar bridges, managed by the Walloon Region. Severe defects were detected mainly in the prestressed piers: a general lack of grouting in the ducts and corrosion of wires were observed for many tendons. The paper reports the programme of investigations that was carried out and describes the solution that was studied for strengthening the structures, including laboratory and on site testing.
