VIBRATION DAMPER FOR WOODEN STRUCTURE BODY AND VIBRATION DAMPING STRUCTURE OF WOODEN STRUCTURE BODY
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
【課題】振動エネルギを全体で効率よく吸収することが可能な木質構造体用制振ダンパ及び木質構造体の制振構造を提供する。【解決手段】一対の木質縦材２それぞれに接合して設けられ、左右横方向に互いに間隔を隔てる左右一対の接合金物５と、これら接合金物の間に配置され、左右横方向両端部に一対の接合部６ａを有する減衰部材６と、減衰部材の各接合部に一端部７ａが接合され、他端部７ｂが一対の接合金物にそれぞれ接合され、減衰部材の各接合部を接合金物それぞれに接続するための左右一対の接続部材７とを備え、減衰部材は、鋼製の平板材で形成され、左右横方向両端部の各接合部及びこれら接合部間の本体部（くびれ部８）を有し、該接合部それぞれから左右横方向中央部に向かう該本体部の外形輪郭が、塑性断面係数及びせん断応力の組み合わせ応力で決定される曲線Ｃで画定される。【選択図】図２
