This paper presents two topics related to the design of large floating structure. One is a proposal of a new type of large floating structure in which the dynamic response characteristics of the edge structure is modified from the other remaining uniform part. According to the understanding on the general response of the uniform large floating structure clarified in the previous report, the response of the edge structure becomes significant. This response will not be acceptable when the structure is used for runway of an airport from the view point of normal function and structural strength. The dynamic response of the whole structure is improved by this modification Another topics is stability of the large floating structure considering elastic deformation of the structure. When some buildings and other structures are built on the floating structure, local elastic deformation must be considered. By using analytical solutions of continuous plate on elastic foundation, the deflection and inclination of the large floating structure under concentrated force and moment are calculated.
