Structural monitoring is intended to control an infrastructure in real time. In order for this to happen, the physical-mechanical parameters that describe the interaction between the environment and the structure to be studied are measured. Thanks to monitoring, it is possible to evaluate the reliability of materials and verify their behavior in real-time, so as to prevent catastrophic events. In particular, today, the needs emerging in the engineering field concern the structural monitoring of existing structures; the purpose is to periodically check the efficiency of the structure, schedule any maintenance and timely interventions in case of anomalies.
Existing infrastructures vulnerability has emerged strongly recently: degradation processes cause progressive damage that over time leads to loss of functionality, until collapse is reached. It is for these reasons that the need to adopt systems for the continuous monitoring of structures is increasingly highlighted, so as to be able to evaluate their performance over time.
Why use monitoring systems?
Through the use of structural monitoring systems it is possible to constantly monitor the state of the structure in order to:
- avoid irreparable damage or structural collapse;
- control the instability progression of phenomena;
- Manage automatic alarm signals in case of exceeding the guard levels;
- Plan prevention and maintenance interventions.
The different monitoring methods.
Depending on the structure type and the parameters to be monitored, different control methods can be chosen. The monitoring method can be static, dynamic or static-dynamic.
ISAAC has developed I‑Check a static and dynamic modular monitoring system that significantly reduces the management costs of the structural monitoring activity, thanks to on-site data processing.
