Protocolli conservativi nell'integrazione delle lacune murarie di ponte Nugent a Capua.

This study proposes a multidisciplinary framework for optimizing the timing and the type of maintenance, based on a methodology developed to update lifetime inspection and repair of brick structures involving a decision tree analysis. Architectural heritage and civil engineering structures are designed to serve public instances, performing safely for decades. In spite of that, no matter how well they are designed, all these structures are going to deteriorate over time. Thus, maintenance strategies should promote solutions that are directed towards preservation and conservation by relying on the existing structural capacity and give preference to stabilization rather than substitution or replacement. In this context, the paper has been proactive in identifying the significance of brick-masonry arch bridges; hence, once the cultural impact has been determined, the next logical step in dealing with these historic structures was to develop a treatment/management plan. The methodology is illustrated by the first results of the project entitled “Improving assessment of Nugent bridge in Capua”, organized by the author, to develop and provide tools that help optimising the life-cycle management of brick-masonry arch bridges, preserving both the physical structure and the historic authenticity, while promoting an effective exchange of good practice between the railway administrations.
