IoT-enabled structural health monitoring: a case study in the Campi Flegrei seismic area

Traditionally, Structural Health Monitoring (SHM) relied on periodic manual inspections and visual assessments, which are inherently limited and subjective in nature, labor-intensive, and unable to detect hidden internal damage. Recently, the integration of the Internet of Things (IoT) has transformed the SHM paradigm by enabling the transition from reactive maintenance to proactive, continuous, and predictive strategies. Indeed, modern IoT systems allow for the deployment of dense, wireless, and cost-effective sensor networks that can capture real-time structural responses and transmit data directly to processing centers. In this context, the present work presents a preliminary application of integrated IoT and SHM techniques for an existing RC structure located in the Campi Flegrei area (near the city of Naples in Italy) that has recently been subjected to several earthquake swarms.
