Abstract

Rapidly increasing maintenance costs of reinforced or concrete bridges have led to an enhanced interest of public authorities in alternative technologies for bridge design. Bridge deck systems made out of fibre reinforced polymers (FRP) offer new options. Maintenance costs and assembly time can be reduced significantly. Especially hybrid structures are competitive, i.e. steel girders combined with a pultruded FRP bridge deck. Based on this technology the design of a highway flyover in the state of Hessen was developed. The exploitation of composite action in it introduces an innovative element in FRP bridge design. The bridge, to be constructed during 2006-07, will be the first major FRP road bridge in Germany. The innovative technology, its economical aspects and the design of the bridge are highlighted in this paper.
