Steel as the main material for bridges is often associated with very large spans due to its favourable relationship between strength and weight. But even with small and medium spans of up to 60 m, steel combined with concrete as a composite bridge can lead to economically justified structures. Based on hot-rolled steel sections, there are several composite solutions that are well known all over Europe. Multiple I-section composite decks and filler beam decks have been standard bridge designs for decades – the latter for more than 100 years.
Please find below some executed examples for both traditional bridge types and innovative bridge solutions such as PreCoBeam bridges.
