Description of the Related Art Vibration energy applied to a building during an earthquake causes plastic deformation of the frame of the building, and may leave large deformation in the building that cannot be used. In order to prevent such large plastic deformation, it is necessary to attenuate the vibration applied during an earthquake. As a typical example of a technique for attenuating a vibration generated in a structure during an earthquake, there is a method using a buckling restrained brace incorporated in a frame surrounded by columns and beams (Japanese Patent Laid-Open No. 6-57820). This technique uses an extremely low yield point steel as the core material of the brace, thereby concentrating the vibration energy of the earthquake on the buckling-restrained brace, and preventing the plastic deformation of the columns and beams of the main frame. In order to realize the effect of the damping member including the buckling restrained brace, the damping member must be yielded before the main frame of the building.

Since the vibration damping member is rigidly joined by bolts or the like, the deformation applied to the vibration damping member is small. Therefore, even if the vibration damping member yields, the yield deformation is only small. For this reason, the energy absorbed by the vibration damping member can be kept small,
The performance of the damping member could not be fully exhibited.
