REINFORCEMENT STRUCTURE OF WOODEN BUILDING
To dispose the reinforcement structure at the corner of the frame regardless of the presence or absence of bracing within the frame to suitably prevent deformation of the frame in an out-of-plane direction and achieve a high vibration damping effect.SOLUTION: In the reinforcement structure of the wooden building, a seismic damper 10 is installed in an inclined manner between pillars 4A, 4B and a beam 2 or a foundation 3 at the four corners of a frame 1 consisting of the pillars 4A, 4B, beam 2 and foundation 3, the seismic damper 10 including a linear inner cylinder 11, a linear outer cylinder 12 that is coaxial with the inner cylinder 11 and partially sheathed and overlaps with the inner cylinder 11 over the entire circumference, and a viscoelastic body 13 bonded to the outer circumferential surface of the inner cylinder 11 and the inner circumferential surface of the outer cylinder 12 with substantially the same thickness over the entire circumference at the overlapping portion of the inner cylinder 11 and the outer cylinder 12. The outer shapes of the inner cylinder 11, the outer cylinder 12, and the viscoelastic body 13 in cross sections perpendicular to the axial direction are substantially similar and concentric to each other. The thickness of the linear portion of the outer cylinder 12 in the thickness direction of the frame 1 is 60% or less of the thickness of the frame 1.SELECTED DRAWING: Figure 1
【課題】フレーム内での筋交いの有無にかかわらず、フレームの角部に配設でき、フレームの面外方向への変形も好適に防止して高い制震効果を得る。【解決手段】木造建築物の補強構造は、柱４Ａ，４Ｂと梁２及び土台３とで構成されるフレーム１内の４つの角部に、直線状の内筒１１と、内筒１１へ同軸で部分的に外装されて全周に亘って内筒１１と重合する直線状の外筒１２と、内筒１１と外筒１２との重合部分で内筒１１の外周面及び外筒１２の内周面へ全周に亘って略同じ厚みで接着される粘弾性体１３とを含む制震ダンパー１０が、角部における柱４Ａ，４Ｂと梁２又は土台３との間へ傾斜状に架設されている。そして、内筒１１と外筒１２と粘弾性体１３とにおける軸方向と直交する横断面の外形は、互いに略相似形で且つ同心であり、フレーム１の厚み方向での外筒１２の直線状部分の厚みは、フレーム１の厚みの６０％以下となっている。【選択図】図１
