Abstract
This paper presents the effect of earthquake on the floating structure. We separate the effect of earthquake into two phenomenon, tsunami and seaquake, based on the Sells' work which treat the disturbance of slightly compressible gravitating liquid caused by a block instantaneously being jerked, And by the analysis that the “POSEIDON”, the floating structure for test, is assumed to be exposed to tsunami, we propose the treatment of tsunami to design a floating structure. At the view of local strength from the bending strength of the bottom shell plate, we propose the treatment of seaquake to design a floating structure.
