Rehabilitation – Bridges
Rail bridges renovation (Tunisia)
Design studies for renovation and upgrading of old railway bridges in Tunisia.
Narbonne Bridge (France)
Diagnostic study of the load-bearing capacity of the Narbonne Bridge. The structure is located in the commune of Narbonne and was first put into service in 1870. It is about 90m long and has presented several pathologies which have led to reflection on the question of restoration or replacement.
The aim of our study was to guide this choice and therefore to provide an answer on the following points:
- firstly, to assess the resistance of the deck to the design loads imposed by the current regulations (Eurocodes);
- to estimate, in a second step, the possible traffic load limitations that would allow the structure to remain in service.
