〔発明の効果〕
弾性域においては、地震等により連結される
構造物の動きの差によつてダンパーが働き、振
動エネルギーが吸収され、それぞれの振れが減
少する。[Effects of the Invention] In the elastic region, a damper works due to the difference in movement of structures connected due to an earthquake, etc., and vibration energy is absorbed, reducing the vibration of each structure.
塑性域においては、変形能力が大きくエネル
ギー吸収能力が高い。 In the plastic region, the deformation capacity is large and the energy absorption capacity is high.

ースプレート側が順次厚くなるように形成して
あるので、モーメント最大部で曲げ耐力が大き
くなり、合理的である。 Since the side surface of the damper body is tapered and the plate width is formed so that it becomes thicker on the base plate side, the bending strength is increased at the maximum moment part, which is reasonable.
ダンパー本体のテーパ形状と板幅を変えるこ
とにより降伏荷重の大きさを自由に設定するこ
とができる。 By changing the taper shape and plate width of the damper body, the magnitude of the yield load can be freely set.
減震装置、免震装置の双方に適用できる。 It can be applied to both seismic attenuation devices and seismic isolation devices.
