DISPLACEMENT-DEPENDENT DAMPER
To provide a displacement-dependent damper which can be installed on a seismic isolation layer irrespective of the form of a seismic isolation bearing.SOLUTION: A displacement dependent damper includes: a lower shoe 2 which has a V-shaped recessed lower slide-contact face 23 on an upper face in an X-direction (a first direction), and which is fixed to an upper part of a lower structure 14 of a construction; an upper shoe 3 which has a V-shaped recessed upper slide-contact face 33 on a lower face in a Y-direction (a second direction) being orthogonal to the X-direction on a horizontal face, and which is fixed to a lower part of an upper structure 15 of the construction; a slider 4 having a lower slide-contact face which can slide with respect to the lower slide-contact face 23 in the X-direction and an upper slide-contact face 46 which can slide with respect to the upper slide-contact face in the second direction; and a compression spring 51 (an elastic member) which is disposed between the upper shoe 3 and the upper structure 15, and is elastically deformable in a vertical direction.SELECTED DRAWING: Figure 3
【課題】免震支承の形態にかかわらず免震層に設置可能な変位依存型ダンパーを提供する。【解決手段】上面にＶ字形の凹状の下摺接面２３をＸ方向（第１方向）に有し、構造物の下部構造体１４の上方に固定される下沓２と、下面に逆Ｖ字形の凹状の上摺接面３３を、Ｘ方向と水平面上において直交するＹ方向（第２方向）に有し、構造物の上部構造体１５の下方に固定される上沓３と、下摺接面２３に対してＸ方向に摺動可能な下摺動面と、上摺接面に対して第２方向に摺動可能な上摺動面４６を備える摺動子４と、上沓３と上部構造体１５との間に設けられ鉛直方向に弾性変形可能な圧縮ばね５１（弾性部材）と、を有する。【選択図】図３
