PROBLEM TO BE SOLVED: To provide a reinforcement vibration control device for preventing damage of a bending part of a vibration control element, by maintaining damping performance of earthquake vibration, and also improving holding bearing force of the vibration control element, without increasing the installation number of vibration control devices, even in a building of a medium-low layer increased in a fixed load.SOLUTION: A reinforcement vibration control device is composed of the vibration control element 7 and a vibration control element support part 9, and the vibration control element is constituted of a first frame installation surface part 10a, a second frame installation surface part 10b, a first rising part 11a rising from an inside end part of the first frame installation surface part, a second rising part 11b rising from an inside end part of the second frame installation surface part and an upper side surface part 13 for connecting between the first rising part and the second rising part and receiving earthquake acting force, and the vibration control element support part comprises a circular arc-shaped first side surface part 15 and a circular arc-shaped second side surface part 17, and the first side surface part is arranged in the inside vicinity of a first bending part 16a formed of the first rising part and the upper side surface part, and the second side surface part is arranged in the inside vicinity of a second bending part 16b formed of the second rising part and the upper side surface part.
【課題】固定荷重の増大した中低層の建屋においても、制震デバイスの取付け個数を増さずに地震振動の減衰性能を維持し、且つ制震素子の保有耐力を向上させて制震素子の曲げ部の破損を防止する補強制震デバイスを提供する。【解決手段】制震素子７と制震素子支持部９とからなり、制震素子は、第１の枠取付面部１０ａおよび第２の枠取付面部１０ｂと、第１の枠取付面部の内側端部から立ち上がる第１の立上部１１ａと、第２の枠取付面部の内側端部から立ち上がる第２の立上部１１ｂと、第１の立上部および第２の立上部間を繋ぎ、地震作用力を受ける上辺面部１３とにより構成され、制震素子支持部は、円弧状の第1の側面部１５と、円弧状の第２の側面部１７とを備え、第１の側面部が第１の立上部と上辺面部とで形成される第１の曲げ部１６ａの内側近傍に配され、第２の側面部が第２の立上部と前記上辺面部とで形成される第２の曲げ部１６ｂの内側近傍に配される。【選択図】図３
