Modern steel or steel composite bridges need modern solutions in steel: often thick heavy plates play a crucial role in bridge building, possibly used as flange plate in heavy bridge beams or as thick deck plate in a trough bridge. Depending on the application thick heavy plates allow efficient fabrication or potentially increase the sustainability of a bridge construction. As today especially fabrication efficiency and durability gain importance, it leads to an increase in the application of thick heavy plates. However, when designing with thick heavy plates often the designer reaches technical or regulatory limits. This report will show some solutions to overcome these existing restraints, e.g. improved possibilities in the production of thick thermomechanically rolled steels or extension of the simplified brittle fracture analysis according to Table 2.1 of EN 1993‐1‐10. The consistent exploitation of these possibilities opens a variety of new advantageous options in constructing road or railway bridges.

In vielen europäischen Ländern ist die Infrastruktur – sowohl bei Straßen‐ als auch bei Eisenbahnbrücken – in die Jahre gekommen und benötigt deutliche Investitionen, um dem stetig wachsenden Bedarf an Mobilität und Güterverkehr gerecht zu werden. Stahl‐ bzw. Stahlverbundbrücken bieten in diesem Zusammenhang eine effiziente und sehr nachhaltige Lösung. So ist Stahl, aufgrund seiner unbegrenzten Recyclefähigkeit im Allgemeinen, bereits der ideale Werkstoff für nachhaltige Konstruktionen, aber besonders wenn der Konstrukteur oder Fertiger die Potentiale, die sich heute aufgrund intelligenter Produktentwicklungen bei der Stahlherstellung bieten, konsequent ausschöpft, können sehr wirtschaftliche und außergewöhnliche Bauwerke realisiert werden. Es zahlt sich daher aus, bereits in der Planungsphase auf moderne Stahlgüten und Qualitätsstähle zu setzen, wie z. B. verbesserte Längsprofilbleche oder höherfeste thermomechanisch gewalzte bzw. vergütete Stähle. Neben einer hocheffizienten, kostenoptimierten Fertigung erlaubt dies häufig auch eine schlankere, ansprechendere Ästhetik in der Architektur. Dieser Beitrag wird einige dieser Möglichkeiten der Grobblechherstellung zur Unterstützung des Stahlbaus hervorheben.

In many European countries, both road and railway infrastructure needs intensive investment to keep up with the growing demands of mobility [1] and goods traffic. Steel or steel‐concrete composite bridges offer viable and very sustainable solutions in this context [2]. Owing to its unlimited recyclability, steel can generally be regarded as the ideal material for such sustainable structures. In particular, when designers or fabricators exploit the possibilities of the steel industry available nowadays, very cost‐efficient and remarkable structures are feasible. This paper will highlight some of the newest developments in heavy plates for bridge‐building. For example, the so‐called thick‐plate trough bridges have proved to be a favourable concept for small‐span railway bridges [3]. Very heavy plates with single plate weights of up to 42 t allow these bridges to be built very efficiently from just one or very few single plates. Another interesting development is the so‐called longitudinally profiled plate, which allows the plate thickness to be varied along the actual loading profile. Finally, the benefits of high‐thickness thermomechanically rolled plates (TM steel) will be discussed; these offer an ideal solution as the use of higher‐strength steels in bridge‐building gains more and more ground.
