Abstract
New Italian guidelines for safety assessment of existing bridges were recently approved. This achievement was reached after the increasing number of casualites which clearly demonstrated the need for an in deep consideration of existing bridges. Actually, most of italian bridges already spent around 50 years of their service life and may require extraordinary repairs to achieve satisfactory safety levels according to latest code provisions. The guidelines represent an unprecedented document in the international context: they provide with additional analysis cases with different traffic loads and partial safety factors to be adopted in order to establish the bridge safety class at ultimate limit state. After introducing the main scope of the work, a preliminary case-study bridge with relative outcomes is proposed.File | Dimensione | Formato | |
