The newly developed traffic speed deflectometer (TSD) is a device used for pavement velocity/deflection measurements and is investigated here in numerical simulations as a means of bridge damage detection. A TSD vehicle model containing five displacement sensors is simulated crossing a simply supported finite element beam containing damage simulated as a loss in stiffness of one of the elements. Time-shifted curvature is derived from the displacements and is proposed as a novel damage indicator, which removes the influence of the road profile and all vehicle motions except for pitch. Results show that the time-shifted curvature can be reliably used as a damage indicator in the presence of noise and changes in transverse position of the vehicle on the bridge.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||Springer||Journal:||Journal of Civil Structural Health Monitoring||Volume:||8||Issue:||3||Start page:||383||End page:||394||Copyright (published version):||2018 Springer-Verlag GmbH Germany, part of Springer Nature||Keywords:||Bridge; Damage; Traffic speed deflectometer; Curvature; Kurtosis; Drive-by; SMH; Health monitoring||DOI:||10.1007/s13349-018-0280-9||Language:||en||Status of Item:||Peer reviewed|
