The preservation of cultural heritage structures demands a multidisciplinary approach to gather essential information for guiding maintenance, protection, and restoration efforts, with the goal of preserving their aesthetic, historical, and functional integrity.

Achieving this result requires an integrated process, combining dynamic numerical modeling and distributed modular measurements within a single adaptive optimization framework. This comprehensive synthesis is now feasible through a dynamic finite element model (DFEM) mutual optimization procedure, that we previously introduced in the literature. This procedure, integrating a digital model with a physical monitoring counterpart into a self-updating hybrid ‘phygital’ system, reframes the role of the monitoring system from an ancillary position to an essential component of the system, due to the need of detecting the degree of freedom of the structure, which, from one side, are needed to tune the dynamic model, and, on the other side, might be variable, depending not only on external excitatory sources, but also on the non-homogeneity of the structure, as well as on its degradation along time. With this respect, the key features of the monitoring solution, that has been already applied in integration with the DFEM procedure in the context of cultural heritage, are discussed through a past case study, referred to the ancient Roman bridge (2nd century BC) over the Savuto River, found between the municipalities of Scigliano and Altilia (Calabria Region, Italy).

Abstract
The preservation of cultural heritage structures demands a multidisciplinary approach to gather essential information for guiding maintenance, protection, and restoration efforts, with the goal of preserving their aesthetic, historical, and functional integrity. In this context, understanding the structure dynamic behavior and predicting the potential structural changes over time is crucial for assessing its overall structural health. Achieving this result requires an integrated process, combining dynamic numerical modeling and distributed modular measurements within a single adaptive optimization framework. This comprehensive synthesis is now feasible through a dynamic finite element model (DFEM) mutual optimization procedure, that we previously introduced in the literature. This procedure, integrating a digital model with a physical monitoring counterpart into a self-updating hybrid ‘phygital’ system, reframes the role of the monitoring system from an ancillary position to an essential component of the system, due to the need of detecting the degree of freedom of the structure, which, from one side, are needed to tune the dynamic model, and, on the other side, might be variable, depending not only on external excitatory sources, but also on the non-homogeneity of the structure, as well as on its degradation along time. With this respect, the key features of the monitoring solution, that has been already applied in integration with the DFEM procedure in the context of cultural heritage, are discussed through a past case study, referred to the ancient Roman bridge (2nd century BC) over the Savuto River, found between the municipalities of Scigliano and Altilia (Calabria Region, Italy).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
