Warning results based on the proposed method with different severity degrees. First scenario, the Honghe Bridge (samples 1–3524: training dataset; samples 3525–4405: validation dataset; samples 4406–5286: test dataset with 2% severity degree; samples 5287–6167: test dataset with 5% severity degree; samples 6168–7048: test dataset with 10% severity degree; red solid line: warning threshold I).
