<p>PROBLEM TO BE SOLVED: To provide a floating structure which can obtain volume (displacement), lightweight characteristics and strength characteristics in combination enough to generate sufficient buoyancy and is excellent in economical efficiency, and to provide ocean wind power generation facilities using the floating structure.SOLUTION: A floating structure 3 includes, in a horizontal plane view, three leg parts 21 radially extended at every 120° and a stand-up part 22 which allows base end sides of respective leg parts to be connected to a circumferential surface of the stand-up part. The leg parts 21 have a cross-section of such a substantially square cylindrical concrete box body that a hollow space is formed on an inner part, and the stand-up part 22 has a cross-section of such a cylindrical concrete box body that a hollow space is formed on an inner part likewise respectively, and such concrete box bodies are constituted with plain concrete to which corrosion-resistant and high-tension fibers are added.</p> |
