その上部にはワイヤ２の中間部２Ｃが連結されている。Furthermore, the foundation of the high-rise building is equipped with a damper 8 that suppresses displacement of the intermediate portion of the wire 2 in its axial direction. This damper 8 has a piston 8C with a large number of small holes 8b (see FIG. 5(b)) in a cylinder 8a filled with oil as shown in FIG.
This damper 8
There are two equipped as shown in Figure 4. 1, that is, the cylinders 8a of the two dampers 8 are connected on the left and right sides fixed to the foundation of a high-rise building l. This connected body 10
is guided so as to be slidable in the left and right direction on a guide rail 11 that spans between the left and right anchors 90, and the intermediate portion 2C of the wire 2 is connected to the upper part of the guide rail 11.

部２ｃの第１図中左方への変位として大き（現われる。With the above configuration, for example, when a high-rise building layer vibrates and its lower layer tilts to the right in Figure 1, one half of the front wire 2 is moved by the solid line in the same figure. Tension is applied to the inclined portion 2d. This tension is applied to the inclined portion 2d between each layer, and the displacement between each layer of the wire 2 due to these tensions is added, resulting in a large displacement of the intermediate portion 2c of the wire 2 to the left in FIG. appear.

エネルギーによって油温が高まる。This displacement of the intermediate portion 2C of the wire 2 is caused by the piston rod 8d of the damper 8 on the left in FIG. 4 retracting to the left and right, and the piston rod 8d of the damper 8 on the right in FIG. It is suppressed by this. That is, the damper 8 generates a flow of oil passing through the small hole 8b of the piston 8C by the displacement of the piston 8C, and at this time generates a resistance force proportional to the speed amplitude of the photographing. Also, the energy at this time increases the oil temperature.

Tension is applied to the inclined portion 2f on the other half of the wire 2, and the displacement between each layer of the wire 2 due to the tension is added.
This appears as a significant rightward displacement of the intermediate portion 2C. Then, the displacement of the intermediate portion 2C of the wire 2 is suppressed by the damper 8. At this time, the piston rods 8d of the two dampers 8 are displaced to the right, opposite to the above-mentioned shaft, and absorb energy.

周期の振動エネルギーを効果的に吸収する。In this way, the displacement between each floor due to the vibration of the high lψ building l is added up and appears as a large displacement of the middle part 2C of the wire 2, so the damper 8 has a speed amplitude of 1% and a low period vibration. Absorb energy effectively.

８のピストンロッド８Ｃを同一軸線上で連結している。FIG. 6 shows another example of the equipment configuration of the damper 8, and in this example, a piston rod 8C of a single-rod type damper 8 is connected to the intermediate portion 2C of the wire 2 on the same axis.
このダンパ８は、上記の例のものと同様にオイルを封入

The cylinder 8a is identified as the anchor 9. In an unusual case, the displacement of the intermediate portion 2C of the wire 2 is caused by the damper 8.
Since it is directly applied to the piston rod 8d, no bending moment is generated. Therefore, the connection structure between the damper 8 and the wire 2 can be simplified.

を利用することができる。In addition to the damper 8, if an active driving force such as an electromagnetic force is used in combination to advance the phase of the II vibration, a more excellent distribution effect can be obtained. For example, if there is a delay in the onset of the swinging sword due to elongation of the wire 2 or play in the mechanical system, the vibration speed of the representative point to be allocated (such as the top floor) is detected, and the direction is adjusted in proportion to this. By applying the opposite stress to the intermediate portion 2C of the wire 2 using the foundation as a reaction force point, an even better vibration damping effect can be obtained. In this case, as a specific example of advancing the phase of the splitter, there is a method of varying the oil pressure in the cylinder 8a, and a linear motor or the like can be used as the driving force.

を発揮することができる。As explained above, the high-rise building according to the present invention has a series of wires strung in a zigzag pattern between the joints of the beams and beams on each floor of the high-rise building, and the wires located on the lower floors of the building The structure is such that the displacement between each floor due to the vibration of the building is added to the intermediate part of the wire, and the displacement of the intermediate part of the wire is suppressed by a damper installed at the foundation of the building. By suppressing wire displacement using a damper, it is possible to actively suppress long-period vibrations in high-rise buildings, and it is also possible to suppress the long-period vibrations of high-rise buildings without having to give buildings a large amount of inertia as in the past. It is possible to demonstrate the distribution function.
