Instantaneous curvature (IC) is presented as a means to determine a local loss of stiffness in a bridge through measurements collected from a passing instrumented vehicle. Moving reference curvature (MRC) is compared with IC as a damage detection tool. It is assumed that absolute displacements on the bridge can be measured by the vehicle. The bridge is represented by a finite element (FE) model. A Half-car model is used to represent the passing vehicle. Damage is represented as a local loss of stiffness in different parts of the bridge. 1% random noise and no noise environments are considered to evaluate the effectiveness of the method. A generic road surface profile is also assumed. Numerical simulations show that the local damage can be detected using IC if the deflection responses can be measured with sufficient accuracy. Damage quantification can be obtained from MRC.||Funding Details:||European Commission Horizon 2020||Type of material:||Journal Article||Publisher:||Springer||Copyright (published version):||2017 Springer||Keywords:||Bridge;Drive-by;Damage detection;Structural health monitoring;SHM;Instantaneous curvature;Moving reference curvature||DOI:||10.1007/s13349-017-0233-8||Language:||en||Status of Item:||Peer reviewed|
