On the use of duplex stainless steels in bridge construction
Maintenance and the related costs in the life time of existing structures are an ever growing problem and bridges are no exception to this rule. Much of the maintenance costs are related to corrosion of steel members. Especially when steel and composite bridges are built in aggressive environments (e.g. close to seawater or in industrial atmospheres) these costs become of major importance. However also concrete bridges are concerned as the re-bars in concrete decks may be subjected to corrosion caused by chloride ingress from de-icing salt or seawater. Consequently the use of a material providing high mechanical properties with a sufficient corrosion resistance for the application in these aggressive environments would lead to economic and durable construction. Further the maintenance costs become predictable, which would increase the quality of the bridge management. Duplex stainless steel is this material with sufficient yield strength, stiffness and toughness as well as an excellent durability in aggressive environments. With a targeted material choice, innovative construction solution may be achieved. However, high material costs, gaps in common knowledge, e.g. on fatigue, as well as fabrication aspects are preventing a wider application of these steels in bridge construction. ; Godkänd; 2008; 20090114 (ysko)
