Abstract
Structural measurements obtained from accelerometers, strain gauges. and tilt meters at Ieodo ocean research station was analyzed. In the acceleration signals, dynamic characteristics of the station were round by using the measured dynamic responses under different wave attacks and were compared with those by numerical analysis. Data from strain gauges and tilt-meters were also analyzed to identify the present state of dynamic response. Effect of wave height on the dynamic characteristics were investigated. The present results and those which will be measured and analyzed later can be used to identify and to assess the state of the station whether it is health or not.
