Modular Composite Bridges with Integral Sheet Piling Abutments for a Time Efficient Construction

Abstract

<p>Composite bridges with sheet pile abutments using modular elements proof to be both economical and ecological efficient under a holistic assessment of costs. However, a standardized solution with widespread acceptance is currently missing in practice. In the present paper, a concept of a modular connection between superstructure in steel composite construction using hot-rolled profiles and integral steel sheet pile abutments is presented: A concept applying combined sheet pile walls for bridge spans up to 30-45m and referencing the Knife Edge-Support (KES). The load paths are analysed numerically, and the influencing parameters are identified. Finally, the experimental test campaign to proof the suitability of the connections will be shown. The research work is supported technically and financially by the FOSTA (Research Association for Steel Application) with funding from Stiftung Stahlanwendungsforschung, Essen (Germany).</p>
