As a result, one steel plate damping damper 1 having the shear deformation panel portion 2 including the two shear deformation panels 5 is created. At this time, the rib plate 8 arranged between the pair of end-plate steel plate damping dampers 1 a includes the one surface 5 of the shear deformation panel 5.

By doing so, a function corresponding to the bending moment acting on the steel plate damping damper 1 is provided. Therefore, regardless of whether the shear deformation panel 5 provided in the shear deformation panel unit 2 is single or plural, both ends of the upper body mounting portion 3 and the lower body mounting portion 4 are connected to each other. The width is made to protrude more than the width.

As described above, FIG. 1 shows the steel plate damping damper 1 having two shear deformation panels 5 in the shear deformation panel portion 2. However, the number of shear deformation panels 5 to be installed is not limited to this. You may connect a sheet. In Figure 2,

A steel plate damping damper 1 having three shear deformation panels 5 is formed in 2. Similarly, it is possible to increase the number of shear deformation panels 5 arranged in the shear deformation panel section 2 by increasing the number of joints of the central steel plate vibration dampers 1b.

Steel plate damping damper 1 manufactured in this way
However, it is arranged between the upper and lower girders of the building to form a vibration control structure. As shown in FIGS. 3 (a) and 3 (b), an upper gusset plate 13 whose surface is oriented in a direction perpendicular to the vertical direction is provided at the lower end of the upper skeleton 11, and an upper gusset plate 13 is provided at the upper end of the lower skeleton 12.

The bolt holes 13a and 14a are provided at the same arrangement intervals as the bolt holes 6c and 7c provided in the.

When the steel plate damping damper 1 is attached to these buildings, as shown in FIG. 3 (b), the steel plate damping damper 1 having the rib plate 8 on its outer surface is arranged. , The upper gusset plate 13 and the lower gusset plate 14 are arranged so as to sandwich the front and back surfaces. These are coaxial with the bolt hole 13a of the upper gusset plate 13 and the bolt hole 6c provided in the upper body mounting portion 3 of the paired steel plate vibration dampers 1,
Tightened with high-strength bolt 9. Similarly, the bolt hole 7c of the lower body mounting portion 4 of the steel plate vibration damper 1
The bolt holes 14a of the lower gusset plate 14 are coaxial with each other, and are similarly tightly connected by the high-strength bolts 9 to form a vibration control structure.

In this way, the upper gusset plate 13,
When the steel plate vibration damper 1 is tightly connected to the lower gusset plate 14 with the high-strength bolt 9, the support plate 10 is provided so as to reinforce the bolt holes 6c and 7c of the steel plate vibration damper 1.

Since the shear deformation panel portions 2 having a plurality of shear deformation panels 5 are configured only by arranging 1b in parallel on the same plane and connecting them via the rib plate 8, it is easy to manufacture with a simple configuration. It is possible to significantly reduce the cost.

As for the characteristics of the shear deformation panel section 2, if the size is the same, even if the shear deformation panel 5 constituting the shear deformation panel section 2 is single, it is divided into a plurality of pieces. However, the history characteristics are similar. Therefore, it is not necessary to give special consideration to the design when applying one steel plate damping damper 1 having the shear deformation panel portion 2 having the plurality of shear deformation panels 5.

When it is desired to provide a plurality of shear deformation panels 5 on the upper gusset plate 13 and the lower gusset plate 14, one steel plate damping damper 1 having a plurality of shear deformation panels 5 in the shear deformation panel section 2 is Compared to the case where a plurality of conventional dampers having a single shear deformation panel 5 are mounted in parallel, the upper body mounting portion 3 and the lower body mounting are mounted even if the load on the steel plate damping damper 1 due to an earthquake or the like is the same. Since the projecting ends 3a, 4a of the portion 4 do not become bulky, the lateral width of the entire steel plate vibration damper 1 attached can be shortened, and the steel plate vibration damper 1 having a burden necessary for a limited space can be obtained. Can be planned arbitrarily. In addition, the number of high-strength bolts used for mounting can be reduced, and the cost can be significantly reduced.

By standardizing the dimensions of the shear deformation panel 5, the steel plate damping damper 1a for the end portion having the shear deformation panel 5 or for the central portion is appropriately matched to the load of the steel plate damping damper 1 due to an earthquake or the like. Steel plate damping damper 1
It suffices to adjust the number of b.
Since the shape and size of the high-strength bolt 9 can be standardized, mass production and cost reduction can be achieved.

For the work at the site, since the steel plate damping damper 1 is simply joined to the upper frame 11 and the lower frame 12 with the high-strength bolts 9, special tools and skills are not required and the workability is good. .
