PROBLEM TO BE SOLVED: To provide a shear damper, stably deformed even in any direction to shear force by earthquake motion, and hardly deformed in the surface-outside direction.SOLUTION: A shear damper 7 is provided between two members for relatively moving by earthquake motion of a building skeleton. The shear damper 7 comprises: a pair of mutually opposed skeleton joining parts 21 and 22 respectively joined to the two members; an energy absorption part 23 interposed between the pair of these skeleton joining parts 21 and 22; and a rib 24 having both ends respectively fixed to the pair of skeleton joining parts 21 and 22 in an outside position in the relative movement direction of the energy absorption part 23. The energy absorption part 23 is composed of a plurality of energy absorbers 40 having both ends respectively continuing with the pair of skeleton joining parts 21 and 22. The respective energy absorbers 40 respectively bend in a bow shape, and also are a constricted shape in a central part of bending, and are juxtaposed in symmetrical arrangement in the relative movement direction so that the projection side of the bending is opposed.SELECTED DRAWING: Figure 5
【課題】 震動によるせん断力に対していずれの方向にも安定して変形し、かつ面外方向に変形し難いせん断ダンパーを提供する。【解決手段】 このせん断ダンパー７は、建物躯体の震動で相対移動する２つの部材間に設けられる。せん断ダンパー７は、２つの部材にそれぞれ接合され互いに対向する一対の躯体接合部２１，２２と、これら一対の躯体接合部２１，２２間に介在するエネルギー吸収部２３と、エネルギー吸収部２３の前記相対移動の方向の外側位置で一対の躯体接合部２１，２２に両端がそれぞれ固定されたリブ２４とを備える。エネルギー吸収部２３は、一対の躯体接合部２１，２２に両端がそれぞれ続く複数のエネルギー吸収子４０からなる。各エネルギー吸収子４０は、それぞれが弓状に屈曲し、かつ屈曲の中心部がくびれる形状であり、屈曲の突出側が対向するように前記相対移動の方向に対称配置で並ぶ。【選択図】 図５
