Abstract: |
The vibrational behavior of a damaged beam-like bridge with one or several nonpropagating edge cracks subjected to a moving vehicle is studied in this paper. The effect of the crack depth, the crack location, the moving vehicle mass, the moving vehicle velocity on the beam-like bridge deflection will be analyzed through a numerical example using vehicle-bridge coupled vibration programme established by MATLAB combined with finite element software ANSYS. The model predictions are shown to be accurate for both the undamaged and the damaged cases, and the vibration characteristics of damaged beam structure subjected to a moving vehicle obtained from the simulation can provide evidence for the damage identification and bridge condition assessment. |
