Description

The present invention relates to a vibration control panel and a building equipped with the vibration control panel.

Conventionally, vibration control devices have been proposed for quickly attenuating vibrations in buildings during earthquakes. For example, Patent Document 1 discloses this type of vibration control device. The vibration control device described in Patent Document 1 discloses connecting plates that are arranged at intervals in the vertical direction as vibration control devices.

JP 2015-194024 A

However, Patent Document 1 does not address the fact that the lifespan of each of the vibration control devices spaced apart in the vertical direction can vary due to the behavior of the columns as vertical members during an earthquake (uneven deformation up and down), which affects the lifespan of the vibration control panel as a whole.

The objective of the present invention is to provide a vibration control panel and building that can reduce variation in life spans and ultimately achieve a longer life span by designing in advance the behavior of vertical members during an earthquake (avoiding uneven deformation up and down) so that multiple vibration control devices can bear seismic forces evenly.

One embodiment of the present invention will be described below with reference to the drawings. Note that the same reference numerals are used to designate the same components in each drawing.

As shown in FIG. 1, the vibration control panel 10 of this embodiment is a device that is installed in a building 1 such as a house, and effectively damps vibrations when vibrations occur in the building 1 due to, for example, an earthquake.

Here, the overall structure of an example of a building 1 equipped with vibration-damping panels 10 will be described. The building 1 can be, for example, a two-story house with a steel-framed framework. Such a building 1 is composed of, for example, a foundation structure, such as a reinforced concrete slab supported on the ground, and a superstructure having a framework (framework) composed of framework members such as column members and beam members, and supported by the foundation structure. The framework members constituting the framework can be standardized members in advance, and are manufactured in a factory and then transported to the construction site and assembled. Similarly, the vibration-damping panels 10 can be at least partially manufactured in advance in a factory and assembled at the construction site. The present invention can also be applied to a unit building in which multiple building units, each of which has a framework formed by steel and wooden beams and columns, are connected. The building 1 is not limited to being two stories high, and may have one or three or more stories. The vibration-damping panels 10 may be provided on any floor of the building 1, or may be provided only on a specified floor or on all floors.

The upper structure comprises a framework consisting of multiple column members and multiple beam members erected between the column members, an exterior wall arranged on the outer periphery of the framework, and a partition wall arranged inside the framework. The vibration control panel 10 of the present invention can be applied to partition walls that divide spaces inside the building 1, and also to exterior walls that divide the indoors and outdoors.

The vibration control panel 10 shown in FIG. 1 is installed between a foundation beam 31 as a lower beam on the first floor and an upper beam 32 on the first floor, as an example. The vibration control panel 10 is arranged at a position where it overlaps the foundation beam 31 and the upper beam 32 in the thickness direction. The foundation beam 31 and the upper beam 32 extend parallel to each other and in the horizontal direction. Note that the foundation beam 31 in this example is a rising part of a reinforced concrete foundation that supports the floor part of the first floor, and an anchor bolt 35 is embedded in the foundation beam 31. Note that the lower beam is not limited to the foundation beam 31 as in this example, and may be, for example, a steel beam that supports the floor part of the second floor or higher. The upper beam 32 can be, for example, a steel beam such as an H-shaped steel that supports the floor part of the second floor or higher, but is not limited to this. Both ends of the upper beam 32 are joined to columns (not shown) as a structure and are supported by the columns.

The vibration-damping panel 10 comprises two vertical members 11 arranged at a distance from each other in the horizontal direction, and a number of vibration-damping devices 20 connected between the two vertical members 11 at intervals in the longitudinal direction of the vertical members 11. The vibration-damping panel 10 is required to comprise at least two vertical members 11, and may comprise three or more vertical members 11. Furthermore, when the vibration-damping panel 10 comprises three or more vertical members 11, one or more vibration-damping devices 20 can be provided between each of a number of adjacent pairs of vertical members 11.

The vertical member 11 has a columnar main body 11a made of, for example, a square steel pipe. The columnar main body 11a of the vertical member 11 is not limited to a square steel pipe, and can be other columnar members such as H-shaped steel. In this example, a flat device fixing portion 11c fixed by means of welding or the like is provided on the mutually opposing side surfaces (opposing surfaces) 11b of the columnar main body portions 11a of the two vertical members 11. A vibration control device 20 is fixed by fastening members such as bolts and nuts across the two device fixing portions 11c provided on the two vertical members 11. In this example, as shown in FIG. 5, the vibration control device 20 can be fixed to the two device fixing portions 11c from both the front and back sides of the vibration control panel 10. In other words, the vibration control device 20 can be fixed by sandwiching the device fixing portion 11c with the two vibration control devices 20 from both the front and back sides. Note that Figure 5 shows a cross section of the vibration control panel 10 taken along line B-B in Figure 1, but does not include the column base 12, foundation beam 31, spacer member 41, reinforcing plate 42, and torsion suppression member 50.

As shown in FIG. 1, in this example, the vibration control devices 20 are arranged at five locations on the two vertical members 11, with a gap between each of them in the vertical direction. However, this is not limited to this, and the vibration control devices 20 may be arranged at four or less locations or six or more locations in the vertical direction. In this example, one vibration control device 20 is attached to the front side and the back side of the device fixing portion 11c at each of the five locations in the vertical direction. That is, in this example, a total of ten vibration control devices 20 are attached between the two vertical members 11. Note that the vibration control devices 20 may be attached to only one of the front side and the back side of the device fixing portion 11c at each of the five locations in the vertical direction. Also, the vibration control devices 20 may be arranged in a stacked manner in the thickness direction. Also, in this example, all the vibration control devices 20 have the same shape, but vibration control devices 20 of different shapes may be used in combination.

In addition, the vibration control device 20 in this example is detachably attached to the device fixing portion 11c. Specifically, the vibration control device 20 can be detachably attached to the device fixing portion 11c of each vertical member 11 using fastening members such as bolts and nuts, screws, or screws. This allows the vibration control device 20 to be easily replaced when it is deformed or deteriorated. Note that the vibration control device 20 may be attached to the vertical member 11 by other methods, and may be fixed in an undetachable state, such as by welding, for example.

Here, the vibration-damping device 20 may be, for example, a steel damper, but is not limited to this, and may be a viscoelastic damper, a friction damper, an oil damper, or the like. The steel damper may be, but is not limited to, low-yield-point steel, which has a lower yield point than the vertical members 11, very low-yield-point steel, or a combination or composite of low-yield-point steel and very low-yield-point steel. In addition, the steel damper as the vibration-damping device 20 in this example is formed in a roughly butterfly shape, and is configured so that the central constricted portion deforms in response to the acting shear force to absorb energy. Note that the shape, material, etc. of the steel damper are not particularly limited as long as it absorbs energy and reduces the displacement when a relative displacement occurs between the two vertical members 11 in the axial direction (the length direction of the vertical members 11) due to an earthquake or the like.

The vertical member 11 has a column base 12 provided at the lower end of the column body 11a and a column head 13 provided at the upper end of the column body 11a. The column base 12 of the vertical member 11 is joined to the foundation beam 31 as the lower beam. The column head 13 of the vertical member 11 is joined to the upper beam 32. Here, the joint between the foundation beam 31 as the lower beam and the column base 12, and the joint between the upper beam 32 and the column head 13 are not a combination of rigid joints and pin joints. In this way, it is possible to make it difficult for uneven deformation to occur in the vertical member 11 during an earthquake. Therefore, the multiple vibration control devices 20 can bear the seismic force evenly, reducing the variation in lifespan and, as a result, the vibration control panel 10 can be extended in lifespan. Note that, as will be described in detail later, the column base 12 of the vertical member 11 in this embodiment is pin-joined to the foundation beam 31 as the lower beam so as to be rotatable in the in-plane direction of the vibration control panel 10. In addition, although details will be described later, the column head 13 of the vertical member 11 in this embodiment is pin-jointed to the upper beam 32 so as to be rotatable in the in-plane direction of the vibration-damping panel 10, and is joined so as to be slidable in the vertical direction. In other words, in this embodiment, the joint between the foundation beam 31 as the lower beam and the column base 12, and the joint between the upper beam 32 and the column head 13 are configured to be rotatable in the in-plane direction of the vibration-damping panel 10. Here, the "in-plane direction of the vibration-damping panel" means any direction in the plane specified by the lower beam (foundation beam 31 in this embodiment) and the upper beam 32. The plane specified by the lower beam (foundation beam 31 in this embodiment) and the upper beam 32 is a vertical plane parallel to the extension direction of the lower beam (foundation beam 31 in this embodiment) and the upper beam 32.

The column base 12 is disposed above the top surface 31a of the foundation beam 31. As shown in FIG. 2, the column base 12 has a flat top plate 14, a flat base plate 15, and a support frame 16 with a U-shaped cross section located between the top plate 14 and the base plate 15. The column base 12 has an internal column base space 17 surrounded by the top plate 14, the base plate 15, and the support frame 16. The upper ends of anchor bolts 35 and fastening members such as nuts 36 are disposed in the internal column base space 17.

The top plate 14 and the base plate 15 can be, for example, steel plates having a rectangular shape in plan view when viewed from the axial direction of the vertical members 11. Here, FIG. 3 is a cross-sectional view taken along line A-A in FIG. 2. Note that fastening members such as nuts 36 fastened to the anchor bolts 35 are omitted in FIG. 3. As shown in FIG. 3, the base plate 15 is provided with through holes 15a for passing through fastening members such as the anchor bolts 35. In this example, only one through hole 15a is formed near the center of the base plate 15, but the number and positions of the through holes 15a can be changed as appropriate.

The support frame 16 has a web portion 16a and a pair of flange portions 16b, 16c connected to both the left and right ends of the web portion 16a. A top plate 14 is fixed to the upper end of the support frame 16 by welding, and a base plate 15 is fixed to the lower end by welding. The top plate 14 is fixed to the lower end of the columnar main body portion 11a by fastening members such as bolts or by welding.

The base plate 15 has a lower surface 15b that constitutes the lower end surface of the column base 12. Here, as shown in FIG. 2, a spacer member 41 is arranged between the lower surface 15b of the base plate 15 of the column base 12 and the top surface 31a of the foundation beam 31 to form a gap 43 below the column base 12. That is, the foundation beam 31 and the column base 12 of this embodiment are joined via the spacer member 41 to form the gap 43. The column base 12 can rotate in the in-plane direction of the vibration control panel 10 relative to the foundation beam 31 due to the gap 43. In other words, the vertical member 11 is pin-joined to the foundation beam 31 with a gap 43 provided between the lower surface of the column base 12 (the lower surface 15b of the base plate 15) and the top surface 31a of the foundation beam 31. As a result, the vertical member 11 is joined to the foundation beam 31 so that it can fall (swing) in the left-right direction. Note that "left-right direction" refers to the horizontal direction in a plan view seen in the panel thickness direction perpendicular to the in-plane direction of the vibration damping panel 10.

The spacer member 41 has a smaller outer dimension in the left-right direction than the base plate 15, and thus at least a gap 43 is formed in the left-right direction. In this example, the spacer member 41 is a flat ring-shaped washer. As shown in FIG. 3, the diameter d (outer diameter) of the outer edge of the spacer member 41 is smaller than the width W (length in the left-right direction) and depth D (length in the front-rear direction perpendicular to the vertical direction and the left-right direction) of the base plate 15. The thickness and shape of the spacer member 41 are not particularly limited as long as it has a smaller outer dimension in the left-right direction than the base plate 15 at least and forms a gap 43 that allows the vertical member 11 to swing in the in-plane direction of the vibration control panel 10.

The column base 12 in this example is fastened to one anchor bolt 35 embedded in the foundation beam 31. In other words, the column base 12 of the vertical member 11 in this example is oscillatably joined (pin-jointed) to the foundation beam 31 using only one anchor bolt 35.

Here, for example, if the column base 12 of the vertical member 11 is joined to the foundation beam 31 using one anchor bolt 35 (for example, semi-rigid or rigid) without placing a spacer member 41 between the column base 12 and the foundation beam 31, that is, so that the gap 43 is not formed, the degree of fixation of the column base 12 to the foundation beam 31 becomes too large compared to the degree of fixation of the upper beam 32 and the column head 13, which are pin-joined. Therefore, for example, during a major earthquake, stress is concentrated on either the left or right flange portion 16b or 16c of the support frame 16 of the column base 12, and buckling deformation may occur in the flange portions 16b and 16c. In contrast, in the vibration control panel 10 of this embodiment, the column base 12 and the foundation beam 31 are joined (pin-jointed) with the spacer member 41 placed between the column base 12 and the foundation beam 31 to form the gap 43, so that stress is less likely to concentrate on the support frame 16 of the column base 12, and buckling deformation of the flange portions 16b and 16c can be suppressed. The details of the connection between the upper beam 32 and the column capital part 13 in this embodiment will be described later.

The vibration-damping panel 10 of this example is provided with a torsion suppression member 50 that connects the vertical members 11 to each other at a position different from the vibration-damping device 20 and can suppress the torsion of the vertical members 11. As shown in Figures 1 and 6, the torsion suppression member 50 is provided across the two vertical members 11 and is fixed to each of the opposing side surfaces 11b using fastening members such as bolts and nuts, screws, or screws. In this example, the torsion suppression member 50 is provided on the upper and lower parts of the two vertical members 11. Specifically, the upper torsion suppression member 50 is located above the device fixing portion 11c, and the lower torsion suppression member 50 is located below the device fixing portion 11c. Note that Figure 6 shows a cross section of the vibration-damping panel 10 taken along line C-C in Figure 1, but the column base 12, foundation beam 31, spacer member 41, reinforcing plate 42, etc. are omitted.

The torsion suppression member 50 in this example is a plate-like member having a bent portion 51, and is configured to elastically deform from the bent portion 51 in response to a relative axial displacement between the two vertical members 11. The bent portion 51 is located at the center of the longitudinal direction of the rectangular torsion suppression member 50. In addition, mounting portions 52 for fixing to the side surface 11b of the vertical member 11 are provided at both longitudinal ends of the torsion suppression member 50. The torsion suppression member 50 can be attached across the two vertical members 11 by fastening the mounting portions 52 to the side surface 11b using a fastening member such as a bolt while each mounting portion 52 is in contact with the side surface 11b of the vertical member 11. The torsion suppression member 50 may be configured to have a gently curved portion instead of the bent portion 51. The torsion suppression member 50 may not have a bent portion 51. The torsion suppression member 50 may also have multiple bent portions 51 and/or curved portions.

The plate-shaped torsion suppression member 50 is also arranged so that the direction in which the vertical member 11 twists is aligned with the direction of the strong axis of the torsion suppression member 50. Specifically, the plate-shaped torsion suppression member 50 of this embodiment is arranged so that the in-plane direction as the direction of its strong axis is aligned with the axial rotation direction about the vertical member 11, which is the direction in which the vertical member 11 twists. In this way, the torsion suppression member 50 is specialized for the torsion suppression function, and the design of the vibration control panel 10 can be prevented from becoming complicated.

More specifically, the torsion suppression member 50 is attached between the two vertical members 11 so that the front or back surface faces upward or downward. In other words, the torsion suppression member 50 extends in the depth direction of the vibration control panel 10. Furthermore, the upper and lower torsion suppression members 50 have the same shape and are attached in an upside-down state. As a result, the upper torsion suppression member 50 is arranged so that the bent portion 51 is downwardly convex, and the lower torsion suppression member 50 is arranged so that the bent portion 51 is upwardly convex.

The torsion suppression member 50 in this example can be formed by bending a rectangular flat steel material at the bent portion 51 and the mounting portion 52, and drilling a hole in the mounting portion 52 for passing a bolt through. The torsion suppression member 50 can be a so-called "curved material" that has a bent or curved portion in advance and can be elastically deformed to become flat when force is applied. The torsion suppression member 50 may also be a flat plate that does not have a bent portion 51, etc.

Here, when the column base 12 is joined to the foundation beam 31 using only one anchor bolt 35 as in this embodiment, there is a risk that the vertical member 11 will gradually rotate axially (rotate around the anchor bolt 35) due to vibrations caused by, for example, multiple earthquakes. In that case, there is a risk that the vibration control device 20 connected between the two vertical members 11 will undergo out-of-plane bending deformation, making it prone to early breakage. In contrast, in this embodiment, the torsion suppression member 50 that connects the two vertical members 11 is provided, making it possible to suppress the axial rotation of the vertical member 11. As a result, it is possible to suppress the vibration control device 20 from undergoing out-of-plane bending deformation and early breakage.

In this example, a flat reinforcing plate 42 is placed between the spacer member 41 and the top surface 31a of the foundation beam 31. As shown in Figures 2 and 3, the reinforcing plate 42 can be a rectangular flat steel material. The reinforcing plate 42 is a member for preventing damage to the top surface 31a of the foundation beam 31 due to contact with the spacer member 41. The reinforcing plate 42 has a larger outer shape in a plan view than the spacer member 41, and is placed so that at least the entire lower surface of the spacer member 41 is supported by the upper surface of the reinforcing plate 42. The reinforcing plate 42 is not a required component, and the spacer member 41 may be placed directly on the top surface 31a of the foundation beam 31.

The column head 13 is pin-joined to the upper beam 32 so that it can rotate in the in-plane direction of the vibration control panel 10. The column head 13 is also joined to the upper beam 32 so that it can slide in the vertical direction. As a result, the vertical member 11 is joined at its upper end in a state where horizontal forces are transmitted to the upper beam 32, and vertical forces and moments are hardly or not transmitted at all.

Figure 4 is an enlarged side view of the column capital part 13. The column capital part 13 has a flat mounting piece 13a fixed to the upper end of the column body part 11a by welding or other means, and a flat column side joint piece 13b fixed to the mounting piece 13a by welding or other means. The column side joint piece 13b is arranged perpendicular to the mounting piece 13a. The column side joint piece 13b has a long hole-shaped through hole 13c that penetrates the column side joint piece 13b in the thickness direction. The through hole 13c is long in the vertical direction and has a dimension in the horizontal direction that allows for some clearance between the bolt that passes through it.

A restraining member 33 is provided on the lower flange 32a of the upper beam 32. The restraining member 33 has a flat mounting piece 33a and a flat beam-side joint piece 33b fixed to the mounting piece 33a by welding or other means. The mounting piece 33a has a hole through which a bolt is inserted, and is fixed to the lower flange 32a of the upper beam 32 using fastening members such as bolts and nuts.

A circular through hole 33c is formed in the beam side joint piece 33b. The beam side joint piece 33b is arranged along the column side joint piece 13b. The restraining member 33 is fixed in advance to the lower flange 32a of the upper beam 32 with fastening members such as bolts and nuts, and the column head 13 is joined to this restraining member 33 to form a vertical roller joint. The beam side joint piece 33b of the restraining member 33 is arranged hanging down from the upper beam 32, and the column side joint piece 13b of the column head 13 is arranged in a state of standing up from the upper end of the column body part 11a. When installing the vertical member 11 between the foundation beam 31 and the upper beam 32, the column base part 12 is joined to the foundation beam 31 with the beam side joint piece 33b and the column side joint piece 13b arranged adjacent to each other so as to be parallel to each other, and then the column head 13 is joined to the upper beam 32. When the column head 13 is joined to the upper beam 32, the bolt 37 as a pin member is inserted through the through hole 33c of the restraining member 33 and the through hole 13c of the column head 13, and a nut is screwed. In other words, by using the bolt 37 as a pin member, the column head 13 is pin-joined to the upper beam 32 so as to be rotatable in the in-plane direction of the vibration-damping panel 10. In addition, by making the through hole 13c a long hole that is long in the vertical direction, the column head 13 is joined to the upper beam 32 so as to be slidable in the vertical direction. In this way, the vertical member 11 can be joined at its upper end to the upper beam 32 so as to be rotatable in the in-plane direction of the vibration-damping panel 10 and slidable in the vertical direction. As a result, the vertical member 11 is joined at its upper end to the upper beam 32 in a state in which a horizontal force is transmitted to the upper beam 32, and vertical forces and moments are hardly or not transmitted at all. In addition, the joining method of the vertical member 11 to the upper beam 32 is set in relation to the joining method of the vertical member 11 to the foundation beam 31 as the lower beam, so it is not limited to a configuration that can rotate in the in-plane direction, and is not limited to a configuration that can slide in the vertical direction. However, as in this embodiment, by joining the vertical member 11 to the upper beam 32 at its upper end so that it can rotate in the in-plane direction of the vibration control panel 10 and can slide in the vertical direction, the vibration control panel 10 does not apply a vertical force or bending moment to the upper beam 32 during an earthquake, making it easier to design the structure including the design of the upper beam 32. In addition, in this example, the through hole 13c of the column head 13 is a long hole, and the through hole 33c of the beam side joint piece 33b is a circular hole, but this is not limited to this. For example, the through hole 13c of the column head 13 may be a circular hole, and the through hole 33c of the beam side joint piece 33b may be a long hole, or both the through hole 13c and the through hole 33c may be long holes.

In this manner, in this embodiment, the joint between the column head 13 of the vertical member 11 and the upper beam 32, and the joint between the column base 12 of the vertical member 11 and the foundation beam 31 are configured to be rotatable in the in-plane direction of the vibration control panel 10. Therefore, compared to a case where both joints are, for example, a combination of a rigid joint and a pin joint, the difference between the degree of fixation of the column head 13 to the upper beam 32 and the degree of fixation of the column base 12 to the foundation beam 31 is smaller, and bending deformation is less likely to occur in the vertical member 11 when inter-layer displacement occurs due to an earthquake or the like. As a result, the multiple vibration control devices 20 can bear earthquake forces evenly, reducing the variation in lifespan and, as a result, the vibration control panel 10 can have a longer lifespan.

In this embodiment, the spacer member 41 is used at the joint between the base 12 and the foundation beam 31, and the bolt 37 is used as a pin member at the joint between the head 13 and the upper beam 32, but the reverse is also possible. In other words, a pin member may be used at the joint between the base 12 and the foundation beam 31, and a spacer member may be used at the joint between the head 13 and the upper beam 32. Furthermore, a spacer member may be used at both joints, or a pin member may be used at both joints. However, from the viewpoint of workability, it is preferable to use a spacer member 41 at the joint between the base 12 and the foundation beam 31, and a pin member such as a bolt 37 at the joint between the head 13 and the upper beam 32, as in this embodiment. This makes it easier to install the vibration control panel 10.

As described above, the vibration control panel 10 of this embodiment is a vibration control panel 10 installed between the lower beam (foundation beam 31) and the upper beam 32 of the building 1, and includes vertical members 11 arranged at intervals from each other, and vibration control devices 20 connected between the vertical members 11 at intervals in the longitudinal direction of the vertical members 11. Each vertical member 11 has a column base 12 joined to the foundation beam 31 and a column head 13 joined to the upper beam 32. The joint between the foundation beam 31 and the column base 12, and the joint between the upper beam 32 and the column head 13 are configured so as not to be a combination of rigid joints and pin joints. With this configuration, the difference between the degree of fixation of the column base 12 to the foundation beam 31 and the degree of fixation of the column head 13 to the upper beam 32 is reduced, making it difficult for bending deformation to occur in the vertical members 11. As a result, the multiple vibration control devices 20 can bear earthquake forces evenly, reducing the variation in lifespan and realizing a long lifespan of the vibration control panel 10.

In the vibration control panel 10 of this embodiment, a flat reinforcing plate 42 is disposed between the spacer member 41 and the top surface 31a of the foundation beam 31. This configuration reinforces the top surface 31a of the foundation beam 31. This reliably prevents, for example, the spacer member 41 from coming into contact with the top surface 31a of the foundation beam 31 and causing damage to the top surface 31a.

In addition, in the vibration control panel 10 of this embodiment, the column base 12 has a flat base plate 15 that constitutes the lower surface 15b of the column base 12, and the spacer member 41 has a smaller outer dimension in the left-right direction than the base plate 15. This configuration makes it easier to swing the vertical member 11 in the left-right direction.

In the vibration control panel 10 of this embodiment, the lower beam is composed of the foundation beam 31, and the column base 12 is fastened to one anchor bolt 35 embedded in the foundation beam 31. This configuration makes it easier to swing the vertical member 11 compared to when multiple anchor bolts 35 are used, and also makes it less likely that the anchor bolt 35 will interfere with the reinforcing bars (not shown) inside the foundation beam 31.

In addition, in the vibration-damping panel 10 of this embodiment, a torsion suppression member 50 is provided that connects the pair of vertical members 11 at a position different from the vibration-damping device 20 and can suppress the twisting of the pair of vertical members 11. With this configuration, it is possible to suppress the rotation of the vertical members 11 around the anchor bolt 35. As a result, out-of-plane bending deformation is less likely to occur in the vibration-damping device 20, and the life of the vibration-damping device 20 can be further extended.

In addition, in the vibration control panel 10 of this embodiment, it is preferable that the torsion suppression member 50 is a plate-like member having a bent portion 51 or a curved portion, and is configured to elastically deform from the bent portion 51 or the curved portion in response to a relative axial displacement between the pair of vertical members 11. With this configuration, the torsion suppression member 50 can suppress the torsion of the vertical members 11, while also making it difficult for the torsion suppression member 50 to break or plastically deform during in-plane deformation between the pair of vertical members 11.

In addition, in the vibration-damping panel 10 of this embodiment, a torsion suppression member 50 is provided on each of the upper and lower parts of the pair of vertical members 11. This configuration makes it even more difficult for the vertical members 11 to twist, and further reduces the load on the vibration-damping device 20.

The present invention is not limited to the configuration of the above-described embodiment, and can be realized in various configurations without departing from the scope of the claims. For example, the vibration control panel 10 in this example is formed so that the entire panel is symmetrical, but is not limited to this and may be asymmetrical.
