| Research Abstract |
In this study, surface cracks and internal defects in concrete were investigated by elastic wave techniques. As a result, surface cracks could be evaluated by employing elastic wave velocity in the case that elastic waves were detected by resonance sensor. In addition, elastic wave techniques were applied to reinforced concrete members in-service. Surface crack and internal defects in the concrete memberswere identified by tomography method of elastic wave velocity.
