Abstract
A system and method for monitoring structural health of a beam using at least one pair of data collection devices mounted along the beam at a spacing distance to define a measurement region. A computer-implemented drive system in communication with the accelerator pairs executes instructions to monitor each measurement regions for propagating transverse waves. After initialization of a propagation speed threshold for each measurement region, a continuous and real-time monitoring loop operates the accelerometers to detect propagations of a transverse wave along the measurement region. For each propagation event, a time delay is determined and, in turn, a propagation speed for the transverse wave based on the time delay and known spacing distance of the measurement region. If the propagation speed violates the threshold set for the measurement region, an alert condition for beam damage is reported and if the propagation speed satisfies the threshold, a success condition is reported.
