| Abstract: |
The requirements for existing bridge structures increased significantly in the last years because of increasing traffic volume and higher total vehicle weights. Strengthening of existing bridges as well as necessary reconstructions are expensive, often complex and strongly influence traffic. Hence, the development of new methods for sustainable bridge constructions with short erection periods becomes a macroeconomic issue. Modular bridge constructions made of precast concrete elements with reinforcement systems made of corrosion-resistant carbon fibre reinforced polymer (CFRP) represent a particularly suitable solution for these demands. Modular systems are reasonable to realise short construction times and the application of durable CFRP reinforcement ensures a longer lifetime of the bridge. This paper reports on a developed concept for a modular system made of prefabricated concrete elements with CFRP reinforcement and on tests investigating the structural behaviour of prestressed CFRP reinforced concrete members. |
