TY - JOUR A1 - Zanon, Riccardo A1 - Rademacher, Dennis A1 - Seidl, Günter A1 - Pak, Daniel T1 - Integral bridge with RS-Overpass technology : step into the future of standard highway overpasses JF - ce/papers N2 - Starting from Germany, the VFT bridge girder technology (prefabricated composite beam) has spread in several European countries in the last decades as further development of the standard steel-concrete composite solution. Its configuration fits perfectly to integral frame bridges built over existing infrastructure with the scope to minimize the traffic disturbance. In this paper a further development with the focus on cost efficiency in span ranges of 40-55 m is proposed: the RS-Overpass technology. The change consists in using standard rolled sections by adapting them into the integral frame bridge configuration, further enhancing the structural efficiency with the benefits of high-steel strength. The constructive details to achieve the polygonal form have been studied to allow easy fabrication and a maximal clearance height over highway traffic lanes. The RS-Overpass solution is conceived as the economic option of standard highway overpasses, with the aim of a overall construction cost reduction of 5%. The possibility of weathering steel or hot-dip galvanization create the unique offer for a maintenance-free solution.

Both the construction and design methods are new [4]. Experiences from the construction of new bridges and discussion between the authors lead to new significant conclusions, which should be included in the new European approval (CEN-TS). The problem of design formulas for concrete dowels is presented.
