Abstract

In this study, impact elastic-wave method was performed at the bottom surface of RC slab cut from an existing highway bridges to survey horizontal cracks. Before measurements by impact elastic-wave method, impact response analysis was applied to determine elastic wave input method, elastic wave detection method and frequency analysis method. Efficiency of analysis-aided impact elastic-wave method was confirmed by drilling and observing the interior of the RC slab by a rod-shaped scanner. Evaluation results by this method are similar to those of visual inspection. Thus, the feasibility of analysis-aided impact elastic-wave method on detection of horizontal cracks in RC slabs of highway bridges was demonstrated.
