Abstract

Wave-guided acoustic emission (AE) signals of a reinforced-concrete slab were evaluated by fatigue testing on a wheel-load machine. Two resonant AE sensors, each with a frequency of 60 kHz, were installed at both ends of a reinforcement rod used as an AE waveguides. The detected AE signals indicated the transverse-wave radiation patterns of vertical and horizontal cracks located at the interface between the concrete and the waveguide. The activity of the cumulative AE energies corresponded to the live-load deflection and vertical-strain phenomena.
