VIBRATION CONTROL STRUCTURE OF TOWER-LIKE STRUCTURE, AND CONSTRUCTION METHOD OF TOWER-LIKE STRUCTURE WITH VIBRATION CONTROL STRUCTURE
To provide a vibration control structure of a tower-like structure capable of improving vibration-damping properties overall a tower-like structure such as offshore wind power generation equipment while reducing the load to a cylindrical foundation of a monopile foundation such as offshore wind power generation equipment due to earthquake motion, etc., and a construction method of a tower-like structure with vibration control structure.SOLUTION: A vibration control structure 8 of a tower-like structure 3 includes a cylindrical seismic damping pile 10 penetrated into the underwater ground 1 within cylindrical foundation 4, which has a predetermined natural frequency. A ground spring section 11 of underwater ground 1 is formed between the outer circumferential surface of the damping pile body 10 and the inner circumferential surface of the cylindrical foundation 4.SELECTED DRAWING: Figure 3
【課題】洋上風力発電設備等の塔状構造物全体の制震性を高め、地震動等による洋上風力発電設備等のモノパイル式基礎等の基礎用筒状体への負担を軽減することができる塔状構造物の制震構造及び制震構造付き塔状構造物の構築方法の提供。【解決手段】塔状構造物３の制震構造８は、基礎用筒状体４内の水底地盤１に貫入された所定の固有振動数を有する筒状の制震用杭体１０を備え、制震用杭体１０の外周面と基礎用筒状体４の内周面との間に水底地盤１からなる地盤ばね部１１が形成されている。【選択図】図３
