VIBRATION CONTROLLER
PROBLEM TO BE SOLVED: To provide a vibration controller that prevents large-scale eccentricity and deformation in a direction orthogonal to a lengthwise direction of a core material, at a location on both ends in a lengthwise direction of a restraining member of the core material or a location in a vicinity due to compressive force exerted on the core material, the vibration controller thereby generating compressive plastic deformation intrinsic to a plasticized part of the core material.SOLUTION: Both ends of a core material 20 being covered with a restraining member 10 and having a plasticized part are connected to two gusset plates that are constituent members of a structure. Mortar 14 is filled in the restraining member 10 as a filler material that covers an outer periphery of the core material 20. A clearance material 25 is fixed on an outer surface of the core material 20, for preventing adhesion of the filler material onto the outer surface and allowing the core material 20 to move relative to the filler material. The clearance material includes first and second clearance materials 25A, 25B that have different thickness dimensions T3, T4. The first clearance material 25A with the smaller thickness dimension is fixed to a location on both ends in a lengthwise direction of the restraining member 10 of the core material 20, or to a location in a vicinity.SELECTED DRAWING: Figure 8
【課題】芯材に作用する圧縮力で芯材における拘束部材の長さ方向の両端部の箇所又はその周辺箇所に、芯材の長さ方向と直交する方向への大きな偏心や変形が生ずることを防止し、芯材の塑性化部に本来の圧縮塑性変形を生じさせる制振装置を提供すること。【解決手段】拘束部材１０で覆われ、かつ塑性化部を有している芯材２０の両端部は、構築物の２つの構成部材であるガセットプレートに結合され、拘束部材１０の内部に芯材２０の外周を覆うモルタル１４による充填材が充填され、芯材２０の外面に、この外面に充填材が付着することを防止して充填材に対し芯材２０が移動することを許容するクリアランス材２５が固定され、クリアランス材には、厚さ寸法Ｔ３，Ｔ４が異なる第１及び第２クリアランス材２５Ａ，２５Ｂがあり、厚さ寸法が小さい第１クリアランス材２５Ａは、芯材２０における拘束部材１０の長さ方向の両端部の箇所及びその周辺箇所に固定されている。【選択図】図８
