STEEL DAMPER

Japanese Patent JP2022178023

A

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
