| Outline of Final Research Achievements |
In this study, non-destructive testing methods were proposed for damage detection of concrete structures. Effectiveness of local through-thickness vibration testing and infrared camera were examined. As the result, these methods are useful for detecting internal cracks and voids in concrete structures, even the surface is covered with carbon fiber sheets. Moreover, a numerical simulation method with concrete cracking analysis (rigid body spring network model) and wave propagation analyses (finite difference time domain method) was proposed. The calculation tool is useful for anomaly detection of measured data obtained from the local vibration testing. In addition, structural performance of damaged structures for a large earthquake can be evaluated with using the calculation tool.
