A new prestressing system for composite bridges with precast concrete deck slabs is introduced. The prestressing system focuses on low costs and a long lifecycle through the economic use of materials, prefabrication and short construction periods. In the bridge system precast deck slabs on top of a steel girder are prestressed by a hydraulic compression joint. The bridge deck is prestressed before the composite connection has been made. The force is transferred to the steel girder by concrete slabs at both ends of the span. In order to do so, the end slabs are connected to the upper flange of the steel girder with dowels. In this paper the distribution of the prestressing force over the dowels is determined, using a simplified analytic model. The study is part of the author's master thesis at the Technical University of Eindhoven.
