Innovative Structural Monitoring as Tool of Preservation and Valorisation of Monumental Architectures: The Case of Neptune Temple in Paestum (Salerno, Southern Italy)

Vibroacoustic heritage monitoring with a standalone system

“…This system, based on the use of broadband high-sensitivity mechanical monolithic seismometers (displacement sensors), was the first step of a path leading to an effective adaptive modular distributed monitoring system, capable to integrate different typologies of sensors, like the one now permanently installed and operational, since 2021, on the Neptune Temple, inside the Paestum and Velia archaeological Park in Paestum (Italy). The system operating on the Neptune Temple, in its basic configuration, consists of 34 seismic sensors (displacement sensors) distributed along three different levels of the temple (foundations, stylobate and architrave), but already set up for further expansion both in terms of number and typology of sensors according to the user requirements [17].…”

Dynamic monitoring of the Temple of Neptune in Paestum (Italy) - Preliminary results

“…The network, which is implemented as an intranet, is an open system and expandable with any type of analog sensor. The seismometers are connected through DAQ (National Instruments -FieldDAQ TM ) to an Intranet to monitor globally and locally the response of the main structural elements [12,15,16]. The network is designed to be expandable by adding new DAQ connected in series, to potentially allow the insertion of new seismometers as well as other types of sensors.…”

“…Among the most well-known and advanced projects, it is worth mentioning the Great Pompeii Project [7], which was conceived as an extraordinary plan of conservation, protection, restoration and enhancement of the archaeological heritage of Pompeii; the projects developed by the Colosseum Archaeological Park [8], like the creation of a database with historical in-formation about the monuments, satellite checking, inspections and visive control of the monuments, surveillance programme of the vegetation; the STORM (Safeguarding Cultural Heritage through Technical and Organizational Resources Management) project [9], concerning the use of optical fibres and acoustic sensors linked to an online platform; the project developed for the Inca site of Machu Picchu [10] [11], where geophysical prospecting (GPR and geoelectrical analysis), techno-morphological analysis of buildings, LIDAR, processing of multispectral satellite images have been used to study the site and prevent the disappearance of the archaeological evidence. This paper focuses on the experimental monitoring activities [12] developed for the temple of Neptune in Paestum within a joint research project carried out by the Department of Civil Engineering (DICIV) at University of Salerno and the Archaeological Park of Paestum and Velia (PAEVE), with the support of private donations through the Artbonus portal of the Italian Ministry of Culture. The seismometer network began as an experimental test site and has been active since 2021.…”

FEM-based models of real-time dynamic structural behavior in archaeology and monumental heritage: the case of ancient Greek colonnades

“…The preservation of historical buildings and infrastructures in cultural heritage sites requires a multidisciplinary approach and suitable tools. Within this framework, a real-time knowledge of their dynamic structural behavior plays a relevant role, For this task, we designed an evolving tailored model tuned with data provided by a distributed monitoring system, optimized in terms of number, sensitivity and position of sensors [1,2]. This approach requires the implementation of an iterative process, based on a mutual and synergic optimization of both the model and the monitoring system.…”
