Summary:In this study, an evaluation method focusing on the propagation time of elastic waves was investigated for detecting horizontal cracks in RC slabs using the electromagnetic pulse method. Specifically, we set several elastic wave receiving points on the surface of RC slab and confirmed the difference of elastic wave propagation time depending on the presence or absence of horizontal cracks by finite element analysis and specimen experiments when the reinforcing bars inside the slab were electromagnetically vibrated. As a result, it was shown that horizontal cracks, which are difficult to be detected by the conventional method based on the amplitude of vibration response, can be evaluated by focusing on the difference of elastic wave propagation time.
