Japanese Patent JP2022179001

A

To provide a vibration damper for wooden structure body which can absorb vibration energy efficiently as a whole, and to provide a vibration damping structure for wooden structure body.SOLUTION: A vibration damper for wooden structure body includes: a pair of left and right joint metals 5 provided being in contact with a pair of wooden vertical materials 2 respectively, and separated from each other in the left-to-right lateral direction; a damping member 6 arranged between these joint metals, and having a pair of joint parts 6a at left-to-right lateral direction both end parts; and a pair of left and right connection members 7 in which one end part 7a is joined to each joint part of the damping member and the other end part 7b is connected to the pair of joint metals, and which connects each joint part of the damping member to each joint metal. The damping member is formed by a steel flat plate material, and has each joint part of the left-to-right lateral direction both end parts and a body part (constricted part 8) between these joint parts, and an outer shape contour of the body part toward a left-to-right lateral direction central part from each joint part is defined by a curve C determined by a combination stress of a plastic section modulus and a shearing stress.SELECTED DRAWING: Figure 2
