- •
Damage detection in bridge structures under moving loads is performed.
- •
Multi-type vibration sensor measurements are analysed for the identification.
- •
Phase trajectory change is used to indicate the structural condition change.
- •
Numerical and experimental investigations are conducted to validate the approach.
