The low cost method consists of the use of a moving vehicle fitted with accelerometers on its axles. In the laboratory experiment, the vehicle-bridge interaction model consists of a scaled two-axle vehicle model crossing a simply supported steel beam. The bridge model also includes a scaled road surface profile. The effects of varying the vehicle model configuration and speed are investigated. A finite element beam model is calibrated using the experimental results and a novel algorithm for the identification of global bridge stiffness is validated. Using measured vehicle accelerations as input to the algorithm, the beam stiffness is identified with a reasonable degree of accuracy.||Funding Details:||European Commission - Seventh Framework Programme (FP7)||Type of material:||Journal Article||Publisher:||Sage Publications||Journal:||Structural Health Monitoring||Volume:||14||Issue:||4||Start page:||317||End page:||331||Copyright (published version):||2015 the Authors||Keywords:||Acceleration; Bridge; Drive-by; Monitoring; Stiffness; Vehicle–bridge interaction||DOI:||10.1177/1475921715578314||Language:||en||Status of Item:||Peer reviewed|
