Abstract: A scour monitoring system may provide a housing that is separated into multiple segments that are fluidically isolated from each other. The scour monitoring system may be position adjacent to a structure to be monitored for bridge scouring. Each of the segments may provide a water-swellable material positioned near or in contact with a fiber Bragg grating (FBG) cable. If water penetrates a segment, the water-swellable material may expand to deform the FBG cable. The wavelength of the FBG cable may be monitored periodically for changes, thereby providing moisture detection when a change in wavelength is detected.

Abstract: The systems and methods described herein are for monitoring the tightness of bolts. The systems and methods may be used with a mechanism to apply a percussive tap and with a recording or monitoring device for detecting and recording the acoustic signals that are generated by the percussive tap. The acoustic signals generated by percussive taps applied to bolts in various looseness states are analyzed and a machine learning model is developed that allows for determining bolt looseness based on the acoustic signals.

Abstract: A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.
