“…Main shock of 2011Tohoku Earthquake (1) In mode 1, the correlation between the predominant frequency and the reservoir water level obtained from ambient vibration records in this research showed similar to the ones in the preceding researches 2), 9) , that is, the predominant frequency becomes lower as the water level becomes higher when the water level is higher than around El. 260 m, which is considered to be the effect of added mass.…”

Structural health monitoring technique was applied to an aged arch dam, where long-term continuous observation of ambient vibration/seismic motion was performed over a span of three years and a half and where the predominant frequency variation along time was detected. As the result, the following was made clear, that is, the structural health of an aged arch dam can be evaluated through the monitoring of the predominant frequency variation which is detected as the result of the long-term continuous observation of ambient vibration/seismic motion.
