VIBRATION CONTROL METHOD AND VIBRATION CONTROL STRUCTURE FOR STEEL FRAME STRUCTURE, AND RACK TYPE WAREHOUSE USING THE SAME
PROBLEM TO BE SOLVED: To reliably restrain vibrations of a steel frame structure such as a rack of a rack type warehouse from being generated by an external force of an earthquake, a strong wind or the like, by a simple structure different from a conventional vibration control structure.SOLUTION: In a vibration control method and a vibration control structure, an upper fulcrum P1 is provided in an upper layer part of a steel frame structure S; a lower fulcrum P2 is provided in a position away by a predetermined distance from the steel frame structure S, on an installation surface G for the steel frame structure; a displacement amplification mechanism 1 with a built-in vibration control damper 2 is obliquely erected between the upper and lower fulcrums P1 and P2; and an attenuation action is added to the steel frame structure S through the utilization of bending deformation of the steel frame structure S to absorb vibrational energy of the steel frame structure S.SELECTED DRAWING: Figure 1
【課題】従来の制振構造とは異なる簡易な構造で、地震や強風などの外力によるラック式倉庫のラックなど鉄骨構造物の振動を確実に抑制する。【解決手段】この制振方法及び構造では、鉄骨構造物Ｓの上層部に上部支点Ｐ１を設けるとともに、鉄骨構造物の設置面Ｇで鉄骨構造物Ｓから所定の距離離れた位置に下部支点Ｐ２を設けて、これら上部支点Ｐ１及び下部支点Ｐ２間に、制振ダンパー２が組み込まれた変位増幅機構１を斜めに架設し、鉄骨構造物Ｓの曲げ変形を利用して鉄骨構造物Ｓに減衰作用を付加し、鉄骨構造物Ｓの振動エネルギーを吸収するようにした。【選択図】図１
