振動が抑制される。When an earthquake force acts on the building to which the friction damper 4 is attached, the frame consisting of the columns 1, 1 and the beams 2.2 is deformed, and the diagonal members 10, 10 forming the brace 3 are subjected to compressive force or A tensile force acts. For example, as shown in FIG. 5, if an axial force P in the compression direction is generated in each of the diagonal members 10 and 10, and if the eccentricity of the mounting position of the diagonal members 10 and 10 is a, then the pair of diagonal members 10 and 10 .10, a couple of 2aP acts, causing the friction plate 5 to rotate in one direction (clockwise in the illustrated example). When the bridge is deformed during an earthquake, the diagonal members 1
Since tensile and compressive axial forces act alternately on O510, . . . , the two friction plates 5.5 rotate in opposite directions. As the friction plates 5.5 rotate, frictional force is generated on the surfaces of the peripheral edges 5a, 5a (surfaces of the friction material 9.9), which are in contact with each other, so that part of the vibration energy of the building is absorbed by this frictional force. Energy is consumed to rotate the friction plate 5.5 against the friction material 9.9, and this energy is converted into thermal energy and absorbed by the friction material 9.9. Thereby, the vibration energy of the building is absorbed by the friction damper 4, and the vibration of the building is suppressed.

The axial movement of 0, . . . is magnified by a factor of r/a on the surfaces of the friction materials 9, . That is,
As shown in FIG. 5, if the rotation angle of one of the friction plates 5 is θ, the movement of the friction members 9, . . . on the surface becomes 2rθ.

等の弾性部材を介在しておけば良い。The energy E lost due to the rotation angle θ is the friction material 9,
If the pressure acting on P1 is the friction coefficient μ, it becomes E-2rθμP. That is, the energy consumed by the friction damper 4 is proportional to the rotation angle θ and the total pressure P. This total pressure P is the pressure introduced by the tightening force of the ports 6 and nuts 7 that connect the friction plates 5.5 to each other. Therefore, it is necessary to tighten the port 6 and nut 7 so that a predetermined axial force is introduced into these friction plates 5.5. Actually, a calibration test of torque and axial force is performed before tightening, and predetermined tightening is performed by tightening bolts with torque to introduce a predetermined axial force into the friction plate 5.5. However, if it is necessary to accurately manage this axial force, for example, as shown in FIG.
It is sufficient to interpose an elastic member such as the like.

特徴である。Incidentally, FIG. 6 shows the history characteristics of the frictional force F (-μP) and the slip amount μθ. The area of this hysteresis characteristic corresponds to the energy lost in one cycle. As shown in the figure, the friction damper 4 is characterized in that it has a wider area of hysteresis characteristics and therefore has a greater energy absorption capacity than other viscous dampers such as oil dampers and hysteresis dampers such as steel bar dampers.

For example, the axial force of the friction plate 5.5 is managed by the spring 13.
However, if the axial force is applied appropriately according to the shaking of the building using hydraulic control, for example, large axial force can be applied only when the building is shaking with large amplitude due to an earthquake, etc. If you weaken the axial force just before it stops, the friction plate 5

摩擦ダンパーを実現することができる。"Effects of the Invention" As explained in detail above, according to the present invention, a friction damper is provided at the intersection of a pair of braces that are intersected in a frame composed of pillars and beams of a building. A, 2
Two plate-shaped friction plates are arranged on the same axis, and these friction plates are pressed against each other in a relatively rotatable state by a fastening means, and friction is applied to at least the peripheral edge of the contacting surfaces of these friction plates. In addition, the brace was connected to the eccentric position of the friction plate inside the mounting position of the friction material so that it could rotate freely, so that when an earthquake force is applied to the building, the two friction plates will move. Each rotates in opposite directions. and,
Due to the rotation of these friction plates, frictional force is generated on the surfaces of the friction materials provided on the opposing surfaces, so a part of the vibration energy of the building is converted into thermal energy and absorbed by the friction materials, and the building Vibration is suppressed. Moreover, since the attachment position of the brace to the friction plate is inside the friction material, the movement of the brace in the axial direction is expanded on the surface of the friction material, thereby improving the efficiency of absorbing energy due to friction as described above. Therefore, according to the present invention, it is possible to realize a friction damper that can efficiently suppress shaking of a building due to earthquake motion or the like.
