Benchmarking time-domain, frequency-domain, and subspace estimators for ambient-vibration modal damping identification

The damping ratio is the modal parameter that is hardest to identify reliably and exhibits the largest scatter in structural health monitoring and operational modal analysis; a trustworthy baseline relies on multi-estimator cross-validation and uncertainty quantification. Measured damping data for high-rise reinforced-...
