Blind separation of structural modes by compact-bandwidth regularization

•A new compact-bandwidth regularization approach is proposed within the signal processing framework for operational modal analysis.•The key idea behind the proposed approach is that an arbitrary mode is compact in the frequency domain.•The spectrum-peak-based rule is proposed for choice of initial m...
