| Abstrait: |
The new tramway line T7 is located in Paris South suburbs; the line is 11 km in length. Many new bridges were built; the main one is a composite bridge crossing the A86 motorway. The deck is a composite box-girder made of weathering steel and reinforced concrete slab. High constraints for road operation have been imposed by the A86 motorway administrator. A multi-criteria analysis of different bridge solutions, including a life cycle cost analysis, demonstrated the economic and environmental interest of using weathering steel for the deck. |
