の回転変形を許容する状態に接続される必要がある。In a damping device such as a variable rigidity device for adjusting the rigidity of seismic resistant elements, a variable damping device for controlling damping force, a high damping device, an energy absorbing device, etc., the head is separated from the frame. It is installed across the seismic resistant element and the frame, but when the legs of the seismic resistant element are rigidly joined to the frame, during out-of-plane deformation or twist deformation of the frame,
Since a relative displacement occurs between the head of the seismic element and the frame in the out-of-plane direction, the seismic damper connected to the head follows the seismic element, so that the seismic element and frame are rotationally deformed about the vertical axis. Must be connected to a state that allows

造が複雑化し、設計が難しくなる。Since the vibration control device functions by switching the connection state with the seismic resistant element when the frame is deformed in-plane, basically the frame and seismic resistant element are rotatably connected around an out-of-plane horizontal axis. Therefore, if it is necessary to connect it so that it can rotate about the vertical axis, the structure of the seismic control device becomes complicated and the design becomes difficult.

形をフレームの面内に規制し、その設計を容易にする。According to the present invention, the legs of the earthquake-resistant frame are pin-joined to the frame in the out-of-plane direction, and the head is separated from the frame so that it can be displaced horizontally relative to the frame. By connecting it to the in-plane rotatably around the horizontal axis, the seismic-resistant structure can be moved without causing relative displacement in the out-of-plane direction between the head of the frame and the frame when the frame is out-of-plane deformed. By following the deformation of itself and avoiding the seismic control device from following the seismic frame when the head is separated from the frame, the deformation that occurs in the seismic control device is restricted within the plane of the frame to facilitate its design. To do.

ればよく、その構造が簡素化され、設計が容易になる。Since the leg portions are pin-joined to the frame in the out-of-plane direction, the out-of-plane rigidity of the seismic frame is reduced, and the head can be displaced horizontally relative to the frame within the in-plane direction. When the frame is out-of-plane deformed or twisted, the seismic frame will follow the displacement due to the out-of-plane deformation of the head with the legs connected to the frame. As a result, out-of-plane deformation of the seismic damping device is avoided, and the seismic damping device only needs to follow the seismic frame during in-plane deformation of the frame, which simplifies the structure and facilitates design.
