Abstract EN
This paper investigates the feasibility of detecting local damage in a bridge using Laser Doppler Vibrometer (LDV) measurements taken from a vehicle as it passes over the bridge.
Six LDVs are simulated numerically on a moving vehicle, collecting relative velocity data between the vehicle and the bridge.
It is shown that Instantaneous Curvature (IC) at a moving reference, which is the curvature of the bridge at an instant in time, is sensitive to local damage.
The vehicle measures Rate of Instantaneous Curvature (RIC), defined as the first derivative of IC with respect to time.
A moving average filter is found to reduce the effects of noise on the RIC data.
A comparison of filtered RIC measurements in healthy and damaged bridges shows that local damage can be detected well with noise-free measurements and can still be detected in the presence of noise.
