Abstract


The Omaru Bridge, which carries the railway track to the Kyushu Island, in Japan, had a metallic superstructure, and as the bridge is close to the sea, had been subjected to the corrosion effect of sea water. As upkeep expenses were high and such structures suffer rapidly from these corrosion effects, the possibility of substituting these metal girders by prefabricated prestressed structures was investigated. The problem of this particular case is a general one, and the solution adopted in the case of the Omaru Bridge is in the nature of an initial trial, that could be applied more generally, after detail improvements, to other metal structures, where the damage of corrosion is increasingly serious. This paper describes in detail the method of preparing the girders, the technique of substitution, auxiliary equipment, prefabrication, etc.
