Abstract
When a very large floating structure, such as a floating airport, is designed the authors have to estimate reliable hydroelastic responses at any point of the structure. The authors have developed the estimating method which is the pressure distribution method of the hydroelastic responses of the very large pontoon type floating structure in deep water condition. In this paper, the results of hydroelastic responses of the structure in shallow water condition are shown. Furthermore. wave drift forces by the experiment and the calculate are illustrated and investigated.
