| Abstract: |
A 132 m long hybrid UHPC-steel bridge with 6 spans is currently being built across the river Fulda in Kassel, Germany. UHPC offers supreme durability characteristics and, hence, has been selected for the replacement of an existing, damaged timber structure. The novel structural concept consists of a hybrid steel – UHPC truss structure and precast UHPC plates for the bridge deck. The deck plates are glued to the upper chords of the truss structure. For the transfer of shear forces from the truss diagonals (steel tubes) to the UHPC chords, prestressed bolted friction connections are used. The paper describes the conceptual design, the final design, accompanying tests and the erection of the bridge structure. A monitoring system will be installed in order to gather practical experience with the new materials and the novel structural concept. |
