Investigating feasibility of drive-by bridge monitoring by laboratory experiments

Furthermore, if the aforementioned two methods could reduce the effect of surface roughness, it would be of great interest whether the processed spectra could be used to detect damage in bridge. To be more specific, it is an interesting subject to examine whether damage in the test bridge would change the pattern of the frequency distribution in the processed spectrum and whether the change in this pattern of a candidate observation could indicate damage in the bridge.
