Abstract

Masonry arch bridges are the oldest bridge structures; thousands of them are still in operation despite the change in the loads carried by them since their construction. Many of them belong to our historical heritage, therefore their management require careful consideration.Assessment of masonry arches is necessary for a several reasons. Arch bridges deteriorate with time, and accordingly their capacity to carry load also declines. To maintain the safety of their operation it is thus necessary to confirm that their load carrying capacity is sufficient for the current and foreseeable applied loads without accelerated deterioration, and therefore that arches remain serviceable.A methodology is proposed in the paper for the assessment and lifetime expectancy of masonry arch bridges with the adaptation of advanced tools for structural analysis and testing.
