Discover the Operational Model for the dynamic monitoring of buildings in Pozzuoli and how it addresses the effects of bradyseism on structural safety<\/p>\n

<\/p>\n

The phenomenon of bradyseism in the Campi Flegrei represents a complex challenge for the safety of existing constructions. In this context, the Municipality of Pozzuoli has initiated an innovative dynamic monitoring project on sample buildings, leveraging advanced technologies and an integrated approach.<\/p>\n

The article illustrates the functioning, objectives, and tools used within the Operational Model Pozzuoli<\/strong>, designed to support prevention, management, and structural assessment activities of the built environment in a seismically vulnerable area.<\/p>\n

Description and objectives of the Operational Model Pozzuoli<\/h2>\n

The Municipality of Pozzuoli<\/strong>[1]<\/sup> has entrusted the EDILTEST S.r.l. Laboratory<\/strong>[2]<\/sup> with the implementation of an \u201cOperational Model Pozzuoli\u201d<\/strong> for monitoring Sample Buildings<\/strong> to support the management of control and monitoring activities of the built environment in the Municipality, an area subject to slow ground deformation known as bradyseism, with the aim of implementing a control procedure and estimating the evolution of damage conditions of the built environment due to seismic phenomena associated with bradyseism.<\/p>\n

The development and implementation of the Operational Model, conducted with the scientific consultancy of Prof. Luigi Petti<\/strong>[3]<\/sup>, involves a multi-scalar and multi-level approach based on the Dynamic Monitoring<\/strong> of Sample Buildings<\/strong> described by Digital Models<\/strong> in the usBIM.geotwin<\/a> environment. The initial phase involves monitoring the first three buildings with accelerometric networks based on Dewesoft<\/strong>[4]<\/sup> technology. The monitoring, on request or triggered (i.e., under seismic conditions), will allow for the control of the evolution of the main parameters of dynamic behavior, including main vibration frequencies and modal shapes, as well as support and calibrate the construction of Digital Models<\/strong> for the development of Digital Twin<\/strong>.<\/p>\n

The importance of structural monitoring<\/h3>\n

The acquisition of data on the behavior of existing constructions in operation and under stress actions \u2013 with particular attention to seismic events \u2013 represents an increasingly relevant and strategic opportunity. A thorough understanding of the structural response of these constructions can be effectively pursued through structural health monitoring (SHM) systems, which are based on the integration of distributed sensor networks, data acquisition and storage systems, infrastructures for information transmission \u2013 even to remote processing platforms \u2013 and advanced software procedures for the analysis, diagnosis, and interpretation of measurements [5,6,7]<\/sup>.<\/p>\n

The regulatory evolution, which has introduced fundamental concepts such as nominal life, usage classes, and specific requirements for certain types of works, underscores the importance of continuous and documented knowledge of the \u201clife\u201d of the construction. In this perspective, monitoring represents an essential tool for detecting over time the static, dynamic, and environmental conditions to which the structure is subjected. This is even more important in complex contexts such as the Flegrean Area, where a bradyseismic phenomenon has long been in place, causing continuous seismic effects.<\/p>\n

As clearly highlighted by the regulations and industry guidelines, the main objectives of monitoring the built environment can enable:<\/p>\n

    \n
  1. Improvement of knowledge of structural behavior:<\/em><\/strong> through the direct correlation between acting forces, deformative states, and calculation models used in design, it is possible to refine technical predictions and increase the reliability of structural analyses;<\/li>\n
  2. Timely detection of anomalies:<\/em><\/strong> continuous monitoring allows for the identification of early signs of structural degradation, both due to cyclic phenomena (e.g., material fatigue) and as a result of exceptional events such as earthquakes, environmental impacts, or anthropogenic stresses;<\/li>\n
  3. Support for the management and maintenance of works:<\/em> <\/strong>the data obtained provide a solid basis for making informed decisions in the management of constructions, planning predictive or extraordinary maintenance interventions more efficiently.<\/li>\n<\/ol>\n

    Dynamic analysis<\/h3>\n

    The objective of the Operational Model Pozzuoli<\/strong> is to allow for a rapid estimation of the evolution of damage<\/strong> as a consequence of the numerous seismic phenomena related to the ongoing bradyseism, analyzing the evolution of the main parameters that describe the dynamic response of buildings and comparing the seismic demand in terms of base acceleration with their resistance.<\/p>\n

    The thorough knowledge<\/strong> of structural behavior also represents a crucial aspect for a reliable assessment of the safety of existing constructions. In particular, the acquisition of real data through monitoring can allow for:<\/p>\n
