Abstract:
Innovations for the optimal use of weathering steel in steel and composite bridge construction The research project “Innovations for the optimal use of weathering steel in steel and composite bridge construction” investigated essential aspects for the optimal use of weathering steel in steel and composite bridge construction. In addition to current investigations on the formation of the corrosion‐inhibiting surface layer in the current atmosphere, the qualification of two geometry‐independent and non‐destructive measuring techniques for crack detection underneath the compact surface layer and their verification on real bridge structures was carried out. Furthermore, tests for the optimization of the slip factor of slip‐resistant prestressed connections of weathering steel were carried out. Basically, the use of weathering steel offers both economic and ecological advantages compared to organically coated structural steel by the formation of its firmly adhering and corrosion‐inhibiting surface layer, especially with regard to the present service life in bridge construction. This article summarises the main research findings to demonstrate the sustainable use and advantages of weathering steel in steel and composite bridge construction under the conditions of use in the current natural atmosphere.
