Abstract
This paper describes a ‘drive-by’ method of bridge inspection using an instrumented vehicle. Accelerometers on
the vehicle are proposed as a means of detecting damage on the bridge in the time it takes for the vehicle to cross the bridge at
full highway speed. For a perfectly smooth road profile, the method is shown to be feasible. Changes in bridge damping, which
is an indicator of damage, are clearly visible in the acceleration signal of a quarter-car vehicle on a smooth road surface
modelled using MatLab. When road profile is considered, the influence of changes in bridge damping on the vehicle
acceleration signal is much less clear. However, when a half-car model is used on a road with a rough profile, it is again possible
to detect changes in bridge damping, provided the vehicle has two identical axles.
