SHEAR DAMPER
PROBLEM TO BE SOLVED: To provide an easy manufactured shear damper showing a high deformation capability and superior durability when a shearing force of external force is received.SOLUTION: A shear damper 1 is a plate-like member with a uniform thickness and has both side fixing parts 2 fixed to each of the two members 10 moved relatively by an external force at a building, both side damaged parts 3 damaged by bending by an external force subsequent to the fixing parts 2, and a connecting part 4 positioned between both side damaged parts 3. A direction of the thickness of the shear damper 1 and a direction in which a shearing force is applied are coincided to each other. An area S of the section is determined by a following formula, S=(6Q/(σ*t))*y, where [t] is a plate thickness, [b] is a width of section spaced apart by a distance [y] from the center of a direction Y between the members at the damaged parts 3, σis a yield strength of material and [Q] is a shear force determined for every building. An area of section perpendicular to a direction Y between the fixing parts 2 and the connecting part 4 is larger than the area S of section determined by the formula described above.SELECTED DRAWING: Figure 3
【課題】 外力によるせん断力を受けた場合に、変形能力が大きくかつ耐久力に優れ、かつ製作が容易なせん断ダンパを提供する。【解決手段】 せん断ダンパ１は厚さが均一な板状であって、建物における外力により相対移動する二つの部材１０にそれぞれ固定される両側の固定部２と、固定部２に続き外力による曲げによって損傷する両側の損傷部３と、両側の損傷部３の間に位置する連結部４とを備える。せん断ダンパ１の厚さの方向とせん断力がかかる方向とが一致する。板厚をｔ、損傷部３における部材間方向Ｙの中心から距離ｙだけ離れた断面の幅をｂ、材料の降伏強度をσｙ、建物ごとに決められるせん断力をＱとした場合、前記断面の面積Ｓが、次式Ｓ＝（６Ｑ／（σｙ・ｔ））・ｙにより決定される。固定部２および連結部４の部材間方向Ｙと垂直な断面の面積は、前記式で決定される断面の面積Ｓよりも大きい。【選択図】 図３
