In recent years, Structural Health Monitoring (SHM) of engineering structures has become an important area of research. This is a broad term which by large also deals with the online detection and identification of structural damage and therefore holds a critical significance for the case of large-scale civil structures where a failure incidence is connected not only to high cost losses but potentially to human loss in the worst-case scenario.
Vibration-based methods are today the fastest growing research area in the SHM field (Fassois and Kopsaftopoulos 2013). However, while such methods are already used for industrial mechanical structures, these are still far from being successfully implemented in large-scale civil structures such as high-rise buildings and bridges. The main reason for this discrepancy is the fact that...
