| Outline of Final Research Achievements |
In this study, a “customized analysis-aided impact elastic wave evaluation system” was developed in which measurement and evaluation processes were customized in accordance with the conditions of target concrete structures. These target structures were tunnel concrete lining, RC slab of highway bridges, and prestressed concrete girder of bridges. Appropriate combination of elastic wave excitation, wave detection, and wave analyzing process were determined by modeling and simulating the target concrete structures using impact response elastic wave analysis. Thus, the measurement results of specimens and the simulation results of analysis model were evaluated for organizing the system. Finally, the proposed “customized analysis-aided impact elastic wave evaluation system” were verified effective by applying to existing target structures in service.
