Recently huge floating structures such as floating airports with length of a few kilo-meters are under planning. Those structures are relatively very thin compared with their plane areas. The study on the structural behavior of such huge floating structures under dynamic loads like wave loads were carried out by Toki and Endo. Most of the researches so far, however, took up structures with footings instead of bare pontoon-typed structures which are more fundamental in shape. In this paper authors first summarized Toki's solution in a more comprehensible form with due corrections of minor mistakes. Then authors applied the formulas to a pontoon-typed floating structure. Finally authors replaced the same structure with an equivalent rectangular flat plate to apply finite element method. The obtained modes and natural circular frequencies were compared with those of a beam analysis.
