In addition, when an elasto-plastic damper is installed on a wall of a structure to suppress vibration, the required energy absorption capacity varies depending on the position and size of the installed wall. Also, it is necessary to prepare a plurality of types of elasto-plastic dampers having different energy absorbing capacities. Usually, in order to adjust the energy absorption capacity of an elasto-plastic damper, its total length is changed, or a plurality of elasto-plastic dampers having a constant energy absorption capacity are installed in parallel, but the total length is changed. When an elasto-plastic damper is constructed with a shape,
The damper itself is a dedicated part that corresponds only to a specific structure, and it lacks versatility, and when the required energy absorption capacity increases, the installation length required for elasto-plastic damper installation becomes too long. Therefore, there is a risk that the installation may be hindered in a place where the installation size is limited, such as between the wall and the beam. Further, in the method of installing a plurality of elasto-plastic dampers in parallel, although the versatility of each elasto-plastic damper can be maintained, it is unavoidable that the installation length of the whole becomes long, and likewise to the wall. There is a risk that the installation to and from the beam will be obstructed.

Energy absorber 1 with slits 16a interposed between them
Since a plurality of 6b are provided in parallel in the base plate direction, it is possible to form an arbitrary number by simply forming the slits 16a in the steel plate.
Therefore, an energy absorber having a desired energy absorption capacity
The vibration energy absorption grating 16 provided with 16b can be easily formed. Further, since only the slits are formed in the steel plate, there is no mechanically movable part, the structure is extremely simple, and the high-density energy absorber 16b can be formed. It becomes possible to provide.

Further, since the width of the installation surface of the base plate on which the vibration energy absorption grid is installed in the direction perpendicular to the installation direction of the vibration energy absorption grid is formed to be twice or more the plate thickness of each vibration energy absorption grid, According to the energy absorption capacity required in the place where the elasto-plastic damper is installed, two or more energy absorption grids are properly installed between the base plates to set the installation length as the elasto-plastic damper in the horizontal direction in FIG. It is possible to adjust the energy absorption capacity without changing, and it is extremely versatile. In addition, since the installation length does not change even if the energy absorption capacity is increased, the installation can be easily performed in a place where installation dimensions such as walls and beams are limited.
