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

The knowledge of the real conditions and their evolution over time is the basis for maintenance processes aimed at the protection and conservation of monumental architectures. In complex conditions, including zones prone, in example, to seismic or hydrogeological hazard, the knowledge of the static and dynamic behaviour of the structures can be achieved using vibration monitoring systems by means of innovative devices and real-time analysis procedures. Currently, the real limit of this methodology is the need to have distributed and modular monitoring systems, adaptable and optimized for the specific structure, with non-invasive sensors (materials, dimensions and weights) characterized by high bandwidths and sensitivities. The paper describes the innovative monitoring project of the Neptune Temple carried out by the Archaeological Park of Paestum and Velia (PAEVE) and by the University of Salerno (UNISA), based on high sensitivity large band sensors developed at UNISA for a large variety of applications of monitoring and control. The monitoring system is a distributed modular continuous data acquisition and storage system, designed to provide real-time information on the dynamic response of monumental architectures due both to natural and human-induced phenomena. It will lead to carry out a research framework aimed at a synergic centralization of the contribution of researchers on the analysis of complex aspects that describe monumental structures as support tool of management plans.
