Submerged Floating Structure is a whole new type of strait crossing which is fixed in the water and supported by the balance between buoyancy and drag force of tension legs. This structure is expected to be widely applicable for railway, road, pedestrian walk and transportation system of material and fluid. In order to realize this construction technology, however, there are a lot of problems to be solved.
One of the most important probrems is parametric excitation which is the response caused by time-varying tension force of legs. In this paper, the parametric excitation phenomena of Submerged Floating Structure are studied analytically and characteristics of the dynamic instability are investigated
