Factors such as the spatial extension of the monitored area, the type, density, and positioning of the sensors on the monitored structural elements discriminate the monitoring and extrapolation strategies of the results for the diagnosis of anomalies.
The combination of extension, number, and type of sensors allows for an ad hoc definition of the structural monitoring and diagnostic strategy with benefits commensurate with the needs.
Complete Extension of the structure:
- The structural work is completely monitored
- The monitoring objective is the control of the overall behavior of the structure
Partial Extension of the structure:
- Monitoring is focused on the single structural element/system/subsystem
- The monitoring objective is the control of the local behavior of the single structural element/system/subsystem

MODEL DRIVEN [MD]
Threshold levels are identified through simulation of damage scenarios with an entity dependent on the acceptable safety levels for the structure.
This mode involves the choice of a Plus instrumentation, capable of continuously detecting predetermined parameters (performance indicators such as deformations, rotations, displacements, vibrational response, etc.). This mode serves as a tool for verifying both the correspondence of the behavior of the structure to theoretical predictions and the regularity of its response over time in pseudo-static and dynamic fields.
DATA DRIVEN [DD] MODE
Thresholds are defined through approaches that guarantee anomaly detection checks and allow the identification of anomalies compared to a standard reference trend for the parameters being monitored.
Sacertis constantly builds and enriches its know-how through the analysis of Big Data derived from continuous infrastructure monitoring and thanks to the extensive databases available that currently collect data from more than 150 structures monitored using the Model Driven approach.
