Abstract
In recent years, various types of floating structures have been planned and constructed for the purpose of the effective utilization in coastal areas. The floating structures such as very large floating structures, floating bridges and submerged floating tunnels should be considered their flexible properties in the design. In this report, hydraulic: model tests of a long flexible floating body are carried out and the results of the motion and the deformation are analyzed in order to evaluate the effect of incident wave direction, wave height, wave period and rigidity.
