ある。In FIG. 1, the viscous damper 5 is not deformed, but in FIG. 2, the center of the brace side fixing surface of the viscous damper 5 is A.
And the center of the beam-side attachment surface of the damper moves to A ′, causing a movement difference δ. Since B is plastically deformed due to δ, it is possible to damp structural deformation due to an earthquake or the like.
The damping force is stronger as the movement difference between the two surfaces of the viscous damper 5 is larger.
