Abstract
This paper presents the structural health assessment of a railway ancient masonry arch bridge located in Bologna, Italy. A three‐dimensional finite element model of the entire bridge, tuned on in situ experimental tests, has been used for the assessment. In particular, the finite element model has been employed to evaluate the structural health of the bridge both in its actual state and in the hypothesis of a structural strengthening intervention.

Summary
The train loads and the train traffic amount increased tremendously in this last century. Many railway masonry arch bridges built in the nineteenth and twentieth centuries are still in service. For this reason and due to the continuous exposure to environmental aggressive conditions, a good number of these bridges suffer important mechanical deteriorations. The procedure applied for the structural health assessment of the railway masonry arch bridge crossing the Reno river in Bologna Italy , see Figure 1, is presented, together with the obtained results. The experimental findings have been used to tune a three-dimensional finite element model of the whole bridge, able to describe the static and dynamic behavior of the structure under service conditions train traffic.
