VIBRATION CONTROL MECHANISM OF COLUMNAR STRUCTURE
PROBLEM TO BE SOLVED: To restrain divergent vibration in a columnar structure of a two-stack shell.SOLUTION: A vibration control mechanism of a two-stack shell steel tower support type chimney is provided with a first cylinder shell 3 and a second cylinder shell 4 in parallel in a steel tower, and the first cylinder shell 3 is fixed to the steel tower. The second cylinder shell 4 is connected to the steel tower via an oil damper capable of damping vibration. A plate 10 projecting outside from the second cylinder shell 4 is provided at an angle θ of 45° to a virtual line P of connecting the center of the first cylinder shell 3 and the second cylinder shell 4. A separation shear layer of wind of turning to the first cylinder shell 3 from the second cylinder shell 4 is kept away to the outside in the radial direction from the second cylinder shell 4 by the plate 10.
【課題】二筒身の柱状構造物において、発散振動を抑制するようにした。【解決手段】二筒身鉄塔支持型煙突の制振機構は、鉄塔内に第一筒身３と第二筒身４を並列に設け、第一筒身３は鉄塔に固定した。第二筒身４は振動を減衰可能なオイルダンパーを介して鉄塔に接続した。第二筒身４から外側に突出したプレート１０は、第一筒身３と第二筒身４の中心を結ぶ仮想線Ｐに対して４５?の角度θに設けた。第二筒身４から第一筒身３に向かう風の剥離せん断層をプレート１０で第二筒身４から径方向外側に遠ざける。【選択図】図３
