| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Until now, hammering test is the most used inspection method for concrete structures. However, the detection accuracy depends on tester’s skill. Moreover, it is difficult to inspect the places where people cannot reach. Therefore we propose the non-contact inspection method using Scanning Laser Doppler Vibrometer(SLDV) and air-coupled sound wave. This time, we carried out experiments using a concrete test piece in which concrete delaminations. As a result, it is confirmed that the concrete delaminations can be detect as well as voids. | |
