Item Description
In order to grasp proper frequencies and their variations over time, including the ones during and/or before/after
seismic events, long-term continuous observation of ambient vibration/seismic motion was undertaken at the
crest of an aged arch dam, which, up to now, revealed the following; 1) The identified proper frequencies of
the dam using ambient vibration data during about five months from summer to winter became lower together
with the dam surface temperature. 2) During the main shock of t
