| Outline of Final Research Achievements |
A non-destructive testing method was investigated to identify an inner damage of steel-concrete composite structure. Especially, a forced vibration test was examined in this research. The local vibration of a composite structure was excited by using a portable shaker. And, the resonant frequency changes were measured in the static loading tests of the SRC beam specimens. As the experimental results, the resonant frequency was significantly decreased on the invisible steel-concrete slip area in the SRC beam specimen. It was indicated that the forced vibration testing by using a portable shaker was useful to identify the inner damage of steel-concrete composite structures.
