抄録

By using a piezoelectric actuator, a real steel bridge can be accelerated locally to detect the effect of small damage like fatigue crack and connection damage as a response to change of vibration. Power spectrum density (PSD) function of the response can give us the indication of the extent of damage before and after the damage. Detailed analysis of PSD before and after damage can give us the location and size (area) of damage. This paper shows the experimental result of damage detection by using local excitation method on a real bridge.
