Beam Damage Detection Under a Moving Load Using Random Decrement Technique and Savitzky–Golay Filter

Beam Damage Detection Under a Moving Load Using Random Decrement Technique and Savitzky–Golay Filter

In this paper, a two-stage time-domain output-only damage detection method is proposed with a new energy-based damage index. In the first stage, the random decrement technique (RDT) is employed to calculate the random decrement signatures (RDSs) from the acceleration responses of a simply supported...
