【 摘 要 】

The use of composite steel structures has gained significant market shares in road bridges across Europe over the last several decades. In particular, when high-strength steel is used, the total weight and the construction depth of the bridge deck can be significantly reduced. This also means lighter substructures and - if necessary - shorter approaching ramps to the bridge. Current developments of the market force designers, producers and fabricators to go new ways and to invent continuously new efficient solutions to save money and time. One big advantage can be achieved when using hot-rolled sections, which are available in higher strength S460 as standard and allow for simpler and more economical construction due to lower fabrication costs. Sophisticated designs with rolled sections allow not only small and medium span lengths, but also longer ones, e.g. in arch bridges with span lengths over 100m. This paper will show new trends in Europe using hot-rolled sections in steel and composite bridges.
