STEEL DAMPER
To provide a steel damper which can sufficiently attenuate vibration energy (earthquake energy) at the generation of vibration since a damper panel is surely plastically deformed at the generation of vibration caused by the earthquake or the like, and can minimize deformation and damage of a building due to vibration.SOLUTION: A damper panel 13a of a steel damper 10A has: a first recessed face area 24 which is formed at a front face 20 in an oval recessed face shape, and is recessed toward a rear face of the damper panel 13a from the front face 20; and a second recessed face area which is formed at a rear face in an oval recessed face shape, and is recessed toward the front face 20 of the damper panel 13a from the rear face. In the steel damper 10A, the first recessed face area 24 having the oval recessed face shape is formed in a substantially-entire area of the front face 20 of the damper panel 13a, and the second recessed face area having the oval recessed face shape is formed in a substantially-entire area of the rear face of the damper panel 13a. When an external force generated by vibration at the generation of the vibration is applied to the steel damper 10A, the steel damper exerts a vibration control function since at least either of the oval first recessed face area 24 and the oval second recessed face area is plastically deformed.SELECTED DRAWING: Figure 1
【課題】地震等による振動発生時にダンパーパネルが確実に塑性変形することで、振動発生時に振動エネルギー（地震エネルギー）を十分に減衰させることができ、振動による建造物の変形や損傷を最小限にすることができる鋼材ダンパーを提供する。【解決手段】鋼材ダンパー１０Ａのダンパーパネル１３ａは、前面２０において楕円の凹面形状に成形されて前面２０からダンパーパネル１３ａの後面に向かって凹む第１凹面エリア２４と、後面において楕円の凹面形状に成形されて後面からダンパーパネル１３ａの前面２０に向かって凹む第２凹面エリアとを有する。鋼材ダンパー１０Ａでは、楕円の凹面形状の第１凹面エリア２４がダンパーパネル１３ａの前面２０の略全域に形成され、楕円の凹面形状の第２凹面エリアがダンパーパネル１３ａの後面の略全域に形成され、振動発生時に振動による外力が鋼材ダンパー１０Ａに加わると、楕円の第１凹面エリア２４と楕円の第２凹面エリアとのうちの少なくとも一方が塑性変形することで制震機能を発揮する。【選択図】図１
