SOUND INSULATING STEEL STRUCTURES IN BRIDGE CONSTRUCTION - PRINCIPLES AND FIRST APPLICATION

SCHALLGEDAEMPFTE STAHLKONSTRUKTIONEN IM BRUECKENBAU - GRUNDLAGEN UND ERSTE ANWENDUNG

The authors deal with the problem of decreasing noise on steel railway bridges by incorporating three-layered bonded steel and plastic systems over a large area; these lead to a considerable decrease in the radiation of noise since they reduce vibration noise. The action of these bonded systems is discussed with reference to the specific requirements of the bridge, such as fixing of the bonded system to the steel structure, corrosion behaviour in the region of the bond and long term behaviour of the system under the action of mechanical loading and temperature. Full scale tests were carried out on two steel box girder railway bridges. The bonding system was mounted in two sections; the noise-reducing plastic was a vinyl acetate copolymer on bridge 1 and a 2-component polyurethane-based material on bridge 2. Results are described.
