に差し込み、これにボルト接合している。 The inner column 1 is vertically joined to one steel beam B, and the other steel beam B is separated. In the illustrated embodiment, the inner column 1 is inserted between two plates 4, 4 protruding from the flange of the beam steel frame B on the lower floor side, as shown in FIG. 2, and bolted thereto.
外柱2,2は他方の梁鉄骨Bに接合され、上記
一方の梁鉄骨Bから切り離される。 The outer columns 2, 2 are joined to the other beam steel frame B and separated from the one beam steel frame B.
この外柱2,2は図示するように内柱1の両側

性を高めてある。 Further, the inner and outer columns 1 and 2 have flanges 1a and 2a, respectively, which protrude in the out-of-plane direction from both side edges, thereby increasing the rigidity of the inner and outer columns 1 and 2 in the out-of-plane direction.
粘弾性体3は第2図、第3図に示すように内柱
1の両面と外柱2,2の内面間に、両柱1,2が
相対的に面内方向に可動状態に接着される。 As shown in FIGS. 2 and 3, the viscoelastic body 3 is bonded between both surfaces of the inner column 1 and the inner surfaces of the outer columns 2, 2 so that the columns 1, 2 are relatively movable in the in-plane direction. Ru.

孔1cは長穴状に明けられている。 In order to prevent the viscoelastic body 3 from peeling off when a force is applied in an out-of-plane direction, in this embodiment, as shown in FIG. They are connected by a U-shaped connecting fitting 5, for example, a U-shaped bolt, and their movement in the out-of-plane direction is restrained. In this case, the bolt hole 1c of the web 1b is opened in the shape of an elongated hole.
