Abstract
This paper presents the results of an experimental investigation, carried out in order to verify
the feasibility of a ‘drive-by’ approach which uses a vehicle instrumented with accelerometers to detect and
locate damage in a bridge. In theoretical simulations, a simplified vehicle-bridge interaction model is used to
investigate the effectiveness of the approach in detecting damage in a bridge from vehicle accelerations. For
this purpose, the accelerations are processed using a continuous wavelet transform and damage indicators are
evaluated and compared. Alternative statistical pattern recognition techniques are incorporated to allow for
repeated vehicle passes. Parameters such as vehicle speed, damage level, location and road roughness are varied
in simulations to investigate the effect. A scaled laboratory experiment is carried out to assess the effectiveness
of the approach in a more realistic environment, considering a number of bridge damage scenarios.
