Abstract: The world is full of historical structures that must be preserved. Given their considerable value, nothing or minimally invasive techniques must be adopted to monitor their health and improve their structural capacity. The operation modal analysis (OMA) is currently the most popular non-invasive methodology to monitor them. Indeed, it allows deriving the dynamic characteristics of the structures through acceleration appropriately positioned sensors. The OMA is employed in the current paper to study a historical complex in the Marche region hinterland (central Italy). First, the dynamic monitoring is carried out to extract the dynamic parameters of the structure. The obtained data are then employed to realise a realistic numerical model by acting on uncertain parameters such as boundary conditions and material parameters.

Keywords: masonry tower; monumental building; structural health monitoring; operational modal analysis; finite element model; FEM; model updating.
