Monitoring of structures and
system identification

Monitoring of structures and system identification

Rapid development of data acquisition and processing capabilities has given rise to major advances in the experimental operational studies, particularly in the field of structural health monitoring. Monitoring of civil engineering structures becomes increasingly popular, as it offers the opportunity to better understand the dynamic behavior of structures under seismic loading, to measure structural response, as well as to detect damages and monitor their evolution. Therefore, it is a significant tool for seismic protection and risk mitigation ensuring integrity and improving resilience, performance and reliability of structures. The Research Unit of SDGEE specializes in monitoring of ordinary structures and infrastructures (e.g. hospitals, bridges and industrial facilities) as well as cultural heritage assets. In particular, our expertise covers the following:

  • Development of temporary and permanent monitoring networks
  • Identification of structural dynamic properties (frequencies, mode shapes, damping ratios)
  •  Finite element model updating procedures to yield more reliable numerical models with respect to the real condition of structures
  • Vulnerability and risk analysis using field monitoring data
  • Structural health monitoring and evaluation of strengthening interventions
  • Real-time monitoring of critical structures and infrastructures
