Abstract:
There are many methods available to diagnosis structural deterioration of concrete structures, the most commonly used is the hammering sound test. Though this method is inexpensive, simple and easy to use, the accuracy of it depends on the subjective sense of the inspector to distinguish defective spots from healthy spots. Thus, to construct diagnostic method of hammering sound test is very promising. In this study, not only hammering sound inspection but also specimen experiment and analysis were conducted. As a result, several feature quantities of hammering sound test are presented and their efficiency are confirmed by comparison between defective spots and healthy spot
