| Research Abstract |
In this study, elastic-wave methods were performed at existing RC members to survey the defects. Before measurements by elastic-wave methods, impact response analysis was applied to determine optimal measurement conditions. Efficiency of 'Analysis-Based Non-Destructive Evaluation Methods' were confirmed by visual inspections. Evaluation results by this method agreed well with results of visual inspection. Thus, validity of the proposed methods for internal defects of concrete was demonstrated.
