Metrological requirements for the broadband vibro-acoustic monitoring system of the San Pietro a Corte church bell tower, Salerno, Italy

This study employs a multi-disciplinary holistic approach to analyze the vibroacoustic fingerprint of the San Pietro a Corte Longobard complex bell tower (Salerno, Italy), using the Dynamical Finite Element Modeling (DFEM) optimization method introduced here. The DFEM aims at mutually optimizing the integration between a modular monitoring system and a digital model, creating an adaptive ‘phygital system’ through a holistic, multi-disciplinary approach. This work, focusing on the initial phases of DFEM procedure, allowed us to design a preliminary monitoring setup, being supported by field surveys. The use of this phygitalsystem could better inform, in the future, the actions needed to protect the immovable heritage assets and produce new data to support novel interpretations of existing material evidence.
