An application of operational modal analysis in modal filtering
Journal of Physics: Conference Series, 2011 Modal filtration in the field of damage detection has many advantages, including: its autonomous operation (without the interaction of qualified staff), low computational cost and low sensitivity to changes in external conditions. However, the main drawback of this group of damage detection methods is its limited applicability to operational data.

Estimation of natural frequencies of the laboratory truss structure with output only subspace and frequency-domain techniques [PDF]
MATEC Web of Conferences, 2020 Non-destructive methods of structural testing are preferred to identify their current state because they do not damage the structure. Modal analysis is one of these methods that can be used for a comprehensive assessment of structural measurements.
