Dynamic characteristics of elastic and rigid circular plates subjected to vertical excitation were considered based on experimental mechanics. Free vibration tests were carried out to obtain coupled natural frequencies for two kinds of plates. Each floating model was vertically excited based on the results of free vibration experiments. The vertical acceleration responses and hydrodynamic pressure distribution were measured. The effects of plate flexibility and anchor stiffness on the dynamic characteristics are investigated though comparative study of flexible and rigid plates. The results will also be used to investigate the dynamic property of floating fishing ports proposed by the authors.
