  2. Description of the Related Art Conventionally, development of a vibration suppression system aimed at reducing the vibration of a wide-range amplitude of a building caused by a large earthquake, a small earthquake, or a wind load has been promoted. As an example of such a vibration damping system, a steel system hysteretic damper disposed in the plane of a building frame and a viscoelastic damper connected in series to the steel hysteretic damper are provided.

Japanese Patent Laid-Open No. 10-280727

  As a member having an elastoplastic history characteristic, there is a corrugated steel sheet in addition to a steel material history damper. Therefore, a damping wall including a corrugated steel plate and a viscoelastic damper connected in series to the corrugated steel plate is conceivable. According to this damping wall, vibration energy can be absorbed by the damping characteristics of the viscoelastic damper, similarly to the above-described damping frame, against small amplitude vibration due to small earthquakes or wind loads. In addition, vibration energy can be absorbed by the elasto-plastic hysteresis characteristics of the corrugated steel plate against large amplitude vibration caused by a large earthquake.

However, the damping wall using the corrugated steel plate may have a problem in terms of function. That is, there is a possibility that the vibration energy absorption performance of the viscoelastic damper is not sufficiently exhibited.
Specifically, buildings with a large aspect ratio, such as high-rise buildings, tend to have superior bending deformation when subjected to vibrations such as earthquakes and winds. Further, reinforced concrete and steel-framed reinforced concrete structures are subject to increased deflection over time when a load or weight is continuously applied to a beam or slab. That is, a creep phenomenon occurs. Furthermore, since the corrugated steel sheet has a characteristic that it can be deformed with low rigidity with respect to the corrugated direction (vertical direction), rocking deformation accompanied by horizontal deformation and vertical deformation occurs when subjected to vibration due to an earthquake or wind. On the other hand, a viscoelastic damper that has a clearance only in one horizontal direction allows deformation of the viscoelastic body only in the horizontal direction. In some cases, a stopper or the like provided in the body damper interferes with peripheral members and the like, thereby inhibiting the deformation of the viscoelastic body. Therefore, this damping wall may not be able to absorb small amplitude vibration energy.

  The present invention has been made in view of the above, and reduces vibration of a wide-range amplitude of a building due to a large earthquake and a small earthquake or wind load, and bending deformation, creep deformation, or rocking of the building.

The viscoelastic damper 20 absorbs the vibration energy of the building by the damping characteristic, and corresponds to the small-amplitude damping means in the claims. The viscoelastic body damper 20 includes resistance plates 21 and 22 and a viscoelastic body 23.

Although the magnitude | size of this clearance 26 is arbitrary, it is preferable that it is more than the length calculated from the allowable shear strain of the viscoelastic body 23, for example.

(Configuration-Pin)
The viscoelastic damper 20 has a first through hole 31 that passes through the resistance plate 21 along the stacking direction, a resistance plate 22 and a viscoelastic body 23 that pass along the stacking direction, and the first through hole.

  The pin 33 is for suppressing horizontal deformation or vertical deformation of the viscoelastic body 23, and corresponds to the penetrating body in the claims. Specifically, the pin 33 is formed of a substantially round bar-shaped steel material, the outer diameter of the pin 33 is approximately the same as the diameter of the first through hole 31, and the periphery of the pin 33 is The first through hole 31 is disposed at a position that contacts the peripheral edge. The pin 33 is threaded on the curved surface portion of the pin 33 where the drop-off prevention nut 34 is located. In order to further enhance the prevention of the pin 33 from falling off, both ends of the pin 33 are provided with a dropping prevention pin 38 that penetrates the pin 33.

The second through hole 32 is formed in a long hole shape having a larger diameter than the outer diameter of the pin 33, and the first space portion 35 and the second space portion are interposed between the second through hole 32 and the pin 33. 36 is provided.
The first space portion 35 is a space portion for allowing the horizontal deformation of the corrugated steel sheet 10 to be shifted from the horizontal deformation of the viscoelastic body 23, and is formed between the peripheral edge of the second through-hole 32 in the major axis direction and the peripheral edge of the pin 33.

Are arranged between each other. Although the magnitude | size of this 2nd space part 36 is arbitrary, for example, it is determined by the allowable shear strain of the viscoelastic body 23 and the amount of vertical deformation of the bending deformation or creep deformation of the building.

The damping wall 1 using the corrugated steel plate 10 configured in this manner basically functions as follows. Hereinafter, the horizontal deformation state and the vertical deformation state will be respectively illustrated. Here, the vertical deformation state at the time of a small earthquake is a concept including bending deformation or creep deformation of a building.
FIG. 4 is a deformation diagram showing a horizontal deformation state of the damping wall 1 shown in FIG. As shown in FIG. 4, the first space 35 is disposed between the peripheral edge of the second through-hole 32 in the major axis direction and the peripheral edge of the pin 33 against small amplitude fluctuations caused by a small earthquake or wind. Therefore, the viscoelastic body 23 of the viscoelastic body damper 20 absorbs vibrational energy by shearing deformation within the range of the first space portion 35.
FIG. 5 is a modified view showing a vertically deformed state of the damping wall 1 shown in FIG. As shown in FIG. 5, the second space portion 36 is disposed between the peripheral edge of the minor axis direction of the second through-hole 32 and the peripheral edge of the pin 33 with respect to vertical swing of small amplitude due to a small earthquake. Therefore, the viscoelastic body 23 of the viscoelastic body damper 20 is vertically deformed within the range of the second space portion 36 to follow these deformations.
FIG. 6 is a deformation view showing a horizontal deformation state of the damping wall 1 shown in FIG. As shown in FIG. 6, when the horizontal deformation of the viscoelastic body damper 20 of the viscoelastic body damper 20 exceeds the size of the first space portion 35 with respect to the horizontal swing of a large amplitude due to a large earthquake. The horizontal deformation of the viscoelastic body 23 of the viscoelastic damper 20 is suppressed by the peripheral edge of the pin 33 coming into contact with the peripheral edge in the major axis direction of the second through hole 32, and the corrugated steel sheet 10 is horizontally deformed. Absorbs vibration energy.
FIG. 7 is a deformation view showing a vertical deformation state of the damping wall 1 shown in FIG. As shown in FIG. 7, if the vertical deformation of the viscoelastic body 23 of the viscoelastic body damper 20 exceeds the size of the second space portion 36 with respect to the vertical swing of a large amplitude due to a large earthquake. When the peripheral edge of the pin 33 contacts the peripheral edge of the second through hole 32 in the minor axis direction, the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 is suppressed, and the corrugated steel sheet 10 is vertically deformed.
As shown in FIGS. 6 and 7, the viscoelastic body 23 of the viscoelastic body damper 20 is excessively deformed horizontally or vertically by the peripheral end of the pin 33 coming into contact with the peripheral end of the second through hole 32. Will not occur. Therefore, it can suppress that the viscoelastic body 23 peels from the resistance plates 21 and 22. FIG.

Next, when the damping wall 1 is rocked, it functions as follows.
In response to a shake at the time of a small earthquake, the viscoelastic body 23 of the viscoelastic body damper 20 performs horizontal deformation and vertical deformation within the range of the first space portion 35 and the second space portion 36, thereby reducing vibration energy. Absorb.
When the horizontal deformation of the viscoelastic body 23 of the viscoelastic body damper 20 is prominent with respect to a shake at the time of a large earthquake, the periphery of the pin 33 will pass through the second penetration if the size of the first space portion 35 is exceeded. The horizontal deformation of the viscoelastic body 23 of the viscoelastic body damper 20 is suppressed by contacting the peripheral edge of the long diameter direction of the hole 32, and the corrugated steel sheet 10 is horizontally deformed to absorb vibration energy. Further, when the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 is dominant, if the size of the second space portion 36 is exceeded, the peripheral edge of the pin 33 is the peripheral edge in the minor axis direction of the second through hole 32. , The vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 is suppressed, and the corrugated steel sheet 10 is vertically deformed.

  In addition to this, the viscoelastic damper 20 absorbs vibration energy with respect to small amplitude fluctuations, and can be arbitrarily selected as long as the horizontal deformation or vertical deformation of the viscoelastic body 23 can be suppressed with respect to large amplitude fluctuations. The structure can be configured. Fig.8 (a) is a front view which shows an example of the damping wall 1 which concerns on a modification, FIG.8 (b) is CC sectional view taken on the line of Fig.8 (a). In this modification, the resistance plate 21 is connected to the concrete beam 3 by a bolt or the like via a connecting member 24, and the resistance plate 22 is connected to the connecting member 11 by a bolt or the like via a connecting member 25. It is connected.

Moreover, Fig.9 (a) is a front view which shows an example of the damping wall 1 which concerns on a modification, FIG.9 (b) is DD sectional view taken on the line of Fig.9 (a). In this modification, a substantially plate-like rib 37 is provided on the side surface of the resistance plate 22, and the rib 37 is fixed to the resistance plate 22 and the connecting member 25 by welding or the like.
According to this structure, the buckling strength of the resistance plate 22 can be improved by the rib 37 fixed to the side surface of the resistance plate 22. That is, even if the horizontal reaction force or the vertical reaction force transmitted to the corrugated steel sheet 10 due to the large amplitude swing becomes excessive and a high stress is generated in the vicinity of the peripheral end of the second through hole 32 that contacts the pin 33, the resistance Deformation of the plate 22 in the out-of-plane direction can be effectively suppressed. The number, arrangement, and form of the ribs 37 may be appropriately designed, and may be arranged between the plurality of pins 33.

(Effect of Embodiment 1)
As described above, according to the first embodiment, the corrugated steel plate 10 and the viscoelastic damper 20 are connected in series, so that the viscoelastic damper 20 acts on the small amplitude swing and the large amplitude swing. Since the corrugated steel plate 10 acts, the shaking of a wide-area building can be reduced. Further, by providing the second space 36 between the peripheral edge of the vertical direction of the second through-hole 32 and the peripheral edge of the pin 33, even if vertical deformation due to bending deformation or creep deformation of the building occurs, it is difficult to Since the vertical deformation of the elastic body damper 20 is allowed, the vibration energy absorbing performance of the viscoelastic body damper 20 can be exhibited.

  Moreover, the resistance plate in the horizontal direction or the vertical direction is provided by arranging the viscoelastic damper 20 so that the stacking direction of the resistance plates 21 and 22 and the viscoelastic body 23 is a horizontal direction orthogonal to the folding line. Since the viscoelastic body 23 can follow the relative displacement of 21 and 22 by shearing deformation, peeling of the viscoelastic body 23 can be prevented.

  Further, by providing the pin 33 penetrating the second through hole 32, the horizontal deformation or the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 reduces the size of the first space 35 or the second space 36. If it tries to exceed, the peripheral edge of the second through-hole 32 and the peripheral edge of the pin 33 come into contact with each other and the horizontal deformation or vertical deformation of the viscoelastic body 23 is suppressed. 23 can be prevented from being damaged or destroyed. Further, the force is transmitted from the resistance plate 22 to the resistance plate 21 via the pin 33, that is, the force is transmitted from the upper concrete beam 3 to the corrugated steel sheet 10 via the pin 33, thereby achieving light weight and horizontal deformation performance. In addition to the function as a rich seismic element, it can function as a vibration control element.

As shown in FIG. 17, when the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 tries to exceed the size of the second space portion 46 with respect to a swing accompanied by a large amplitude bending due to a large earthquake. When the side surface of the nut 44 comes into contact with the end surface of the connecting member 11 in the vertical direction, the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 is suppressed, and the corrugated steel sheet 10 is vertically deformed.

Due to the contact with the end face of the, excessive horizontal deformation or vertical deformation does not occur. Therefore, it can suppress that the viscoelastic body 23 peels from the resistance plates 21 and 22. FIG.

Next, when the damping wall 1 is rocked, it functions as follows.
In response to a shake at the time of a small earthquake, the viscoelastic body 23 of the viscoelastic body damper 20 performs horizontal deformation and vertical deformation within the range of the first space portion 45 and the second space portion 46, thereby reducing vibration energy. Absorb.
When the horizontal deformation of the viscoelastic body 23 of the viscoelastic body damper 20 is prominent with respect to shaking during a large earthquake, if the size of the first space portion 45 is to be exceeded, the through bolt 43 is connected to the second through hole. The horizontal deformation of the viscoelastic body 23 of the viscoelastic body damper 20 is suppressed by abutting the peripheral edge 42 of the major axis direction 42, and the corrugated steel sheet 10 is horizontally deformed to absorb vibration energy. Further, when the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 is dominant, the side surface of the nut 44 comes into contact with the vertical end surface of the connecting member 11 when the size of the second space 46 is exceeded. Thus, the vertical deformation of the viscoelastic body 23 of the viscoelastic damper 20 is suppressed, and the corrugated steel sheet 10 is vertically deformed.

In addition to this, the viscoelastic body damper 20 absorbs vibration energy with respect to small amplitude swing, and with respect to large amplitude swing, the viscoelastic body 23 is deformed horizontally or vertically with respect to large amplitude swing. As long as it can be suppressed, it can be configured with an arbitrary structure. FIG. 18A is a front view showing an example of a damping wall 1 according to a modification, and FIG. 18B is a cross-sectional view taken along the line GG in FIG. FIG. 19 is an enlarged view of region B in FIG. In this modification, auxiliary materials 47a to 47c are provided at both ends of the resistance plates 21 and 22 extending in the fold line direction.

This viscoelastic body 67 can absorb vibration energy by shear deformation of the viscoelastic body 67 when the horizontal or vertical relative deformation occurs in the resistance plates 21 and 22.

(Stopper function)
The damping wall 1 using the corrugated steel plate 10 configured in this manner basically functions as follows.
FIG. 23 is a deformation view showing a horizontal deformation state of the damping wall 1 shown in FIG. As shown in FIG. 23, the first space portion 65 is disposed between the lip 63 and the connection plate 51 for small amplitude fluctuations caused by small earthquakes, winds, and the like, so that the viscoelastic damper 20 The viscoelastic body 23 is horizontally deformed within the range of the first space portion 65 to absorb vibration energy.
FIG. 24 is a deformation diagram showing a vertical deformation state of the damping wall 1 shown in FIG. As shown in FIG. 24, since the second space 66 is disposed between the lip 63 and the resistance plate 21 with respect to vertical swing of small amplitude due to a small earthquake, the viscoelastic damper 20 When the viscoelastic body 23 is vertically deformed within the range of the second space portion 66, it follows these deformations.
FIG. 25 is a modified view showing a bending deformation state of the damping wall 1 shown in FIG. As shown in FIG. 25, since the second space 66 is disposed between the lip 63 and the resistance plate 21 with respect to a swing accompanied by a small amplitude bend caused by a small earthquake, the viscoelastic damper 20 The viscoelastic body 23 bends and deforms within the range of the second space portion 66, thereby following these deformations.
FIG. 26 is a deformation diagram showing a horizontal deformation state of the damping wall 1 shown in FIG. As shown in FIG. 26, if the horizontal deformation of the viscoelastic body 23 of the viscoelastic body damper 20 exceeds the size of the first space portion 65 with respect to the horizontal swing of a large amplitude due to a large earthquake. When the lip 63 comes into contact with the connection plate 51, the horizontal deformation of the viscoelastic body 23 of the viscoelastic body damper 20 is suppressed, and when the corrugated steel sheet 10 is horizontally deformed, vibration energy is absorbed.

Further, when the vertical deformation of the viscoelastic body 23 of the viscoelastic body damper 20 is dominant, if the size of the second space portion 66 is exceeded, the lip 63 comes into contact with the resistance plate 21, and this viscoelastic body. The vertical deformation of the viscoelastic body 23 of the damper 20 is suppressed, and the corrugated steel sheet 10 is vertically deformed.

  In addition to this, the viscoelastic body damper 20 absorbs vibration energy with respect to small amplitude swing, and with respect to large amplitude swing, the viscoelastic body 23 is deformed horizontally or vertically with respect to large amplitude swing.

A first space 68 d is formed between the lip 68 b and the connection plate 51, and a second space 68 e is formed between the lip 68 b and the resistance plate 21.
The lip 69b extends from the end portion 69a of the side wall toward the connection plate 53 disposed at a position orthogonal to the connection plate 51, and is connected to the side wall 69a by welding or the like. The connection plate 53 is a substantially plate-shaped steel material, and is erected on the side surface opposite to the side surface of the resistance plate 21 to which the viscoelastic body 23 is fixed, and is welded to the resistance plate 21 and the connecting member 52. Connected by. By making this lip 69b contact the connection plate 53 in advance, it is possible to restrain deformation of the viscoelastic body 23 in the extending direction of the lip 69b.
