Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same reference numerals are given to the configurations common to each figure.

As shown in FIG. 1, the vibration damping panel 10 of the present embodiment is provided in a building 1 such as a house, and is a device for effectively damping the vibration when the building 1 is vibrated due to, for example, an earthquake or the like. Is.

Here, the overall configuration of an example of the building 1 provided with the vibration damping panel 10 will be described. The building 1 can be, for example, a two-story house having a steel-framed frame. Such a building 1 has, for example, a foundation structure such as a reinforced concrete cloth foundation supported by the ground, and a skeleton (framework) composed of skeleton members such as column members and beam members, and has a foundation structure. It is composed of a superstructure supported by the body. The frame members constituting the frame can be standardized (standardized) in advance, and are manufactured in advance at the factory and then carried to the construction site for assembly. Similarly, the vibration damping panel 10 can be manufactured at least partially in advance at the factory and assembled at the construction site. It should be noted that the present invention is also applicable to a unit building in which a plurality of building units in which a frame is formed of steel and wood beams and columns are connected. The building 1 is not limited to a two-story building, and may have one or three or more floors. Further, the vibration damping panel 10 may be provided on any floor of the building 1, and may be provided only on a predetermined floor or on all floors.

The superstructure consists of a frame composed of a plurality of column members and a plurality of beam members erected between the column members, an outer wall arranged on the outer periphery of the frame, and a partition wall arranged inside the frame. And prepare. The vibration damping panel 10 of the present invention can be applied to a partition wall for partitioning a space inside a building 1 and an outer wall for partitioning an indoor and an outdoor space.

As an example, the vibration damping panel 10 shown in FIG. 1 is installed between the foundation beam 31 as the lower beam on the first floor and the upper beam 32 on the first floor. The vibration damping panel 10 is arranged at a position overlapping the foundation beam 31 and the upper beam 32 in the thickness direction thereof. The foundation beam 31 and the upper beam 32 extend parallel to each other and in the horizontal direction. The foundation beam 31 of this example is a rising portion of a reinforced concrete foundation that supports the floor portion of the first floor, and anchor bolts 35 are embedded in the foundation beam 31. 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 portion of the second floor or higher. The upper beam 32 can be, for example, a steel frame beam such as H-shaped steel that supports the floor portion of the second floor or higher, but is not limited to this. Both ends of the upper beam 32 are joined to a pillar (not shown) as a skeleton, and are supported by the pillar.

A plurality of vibration damping panels 10 are connected between two vertical members 11 arranged at intervals in the horizontal direction and two vertical members 11 at intervals in the length direction of the vertical members 11. A vibration damping device 20 is provided. The vibration damping panel 10 may include at least two vertical members 11 and may include three or more vertical members 11. Further, when the vibration damping panel 10 includes three or more vertical members 11, one or more vibration damping devices 20 can be provided between the two adjacent vertical members 11.

The vertical member 11 has a columnar main body portion 11a made of, for example, a square steel pipe. The columnar main body portion 11a of the vertical member 11 is not limited to the square steel pipe, and may be another columnar member such as H-shaped steel. In this example, a flat plate-shaped device fixing portion 11c fixed by means such as welding is provided on the side surfaces (opposing surfaces) 11b of the columnar main body portions 11a of the two vertical members 11 facing each other. The vibration damping 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 damping device 20 can be fixed to the two device fixing portions 11c from both the front surface side and the back surface side of the vibration damping panel 10. That is, the vibration damping device 20 can be fixed by sandwiching the device fixing portion 11c between the two vibration damping devices 20 from both the front and back sides. Note that FIG. 5 shows a cross section of the vibration damping panel 10 in line BB of FIG. 1, but the description of the column base portion 12, the foundation beam 31, the spacer member 41, the reinforcing plate 42, and the twist suppressing member 50. Is omitted.

As shown in FIG. 1, in this example, the vibration damping devices 20 are arranged at five locations at intervals in the vertical direction with respect to the two vertical members 11, but the present invention is not limited to this, and the vibration damping devices 20 are arranged vertically. It may be provided at 4 or less locations or 6 or more locations in the direction. Further, in this example, one vibration damping device 20 is attached to each of the front surface side and the back surface 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 10 vibration damping devices 20 are attached between the two vertical members 11. The vibration damping device 20 may be attached to only one of the front surface side and the back surface side of the device fixing portion 11c at five locations in the vertical direction. Further, the vibration damping device 20 may be arranged by stacking a plurality of the vibration damping devices 20 in the thickness direction thereof. Further, although all the vibration damping devices 20 having the same shape are used in this example, vibration damping devices 20 having different shapes may be used in combination.

Further, the vibration damping device 20 of this example is detachably attached to the device fixing portion 11c. Specifically, the vibration damping device 20 can be detachably attached to the device fixing portion 11c of each vertical member 11 by using a fastening member such as a bolt and a nut, a screw, or a screw. According to this, when the vibration damping device 20 is deformed or deteriorated, it can be easily replaced. The vibration damping device 20 may be attached to the vertical member 11 by another method, or may be fixed in a non-detachable state such as by welding.

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 a low yield point steel having a lower yield point than the vertical member 11, an extremely low yield point steel, or a combination or a composite of a low yield point steel and an extremely low yield point steel. It is not limited to. Further, the steel damper as the vibration damping device 20 of this example is formed in a substantially butterfly shape, and is configured so that the central constricted portion is deformed according to the acting shear force to absorb energy. There is. The steel damper absorbs energy and reduces the displacement when a relative displacement in the axial direction (length direction of the vertical member 11) occurs between the two vertical members 11 due to an earthquake or the like. If so, the shape, material, and the like are not particularly limited.

The vertical member 11 has a column base portion 12 provided at the lower end portion of the columnar main body portion 11a, and a stigma 13 provided at the upper end portion of the columnar main body portion 11a. The column base portion 12 of the vertical member 11 is joined to the foundation beam 31 as the lower beam. Further, the stigma 13 of the vertical member 11 is joined to the upper beam 32. Here, the joint portion between the foundation beam 31 and the column base portion 12 as the lower beam and the joint portion between the upper beam 32 and the stigma 13 are not a combination of rigid joint and pin joint. By doing so, it is possible to prevent uneven deformation in the vertical direction from occurring as the behavior of the vertical member 11 at the time of an earthquake. Therefore, since the plurality of vibration damping devices 20 can evenly bear the seismic force, the variation in life can be reduced, and as a result, the life of the vibration damping panel 10 can be extended. Although the details will be described later, the column base portion 12 of the vertical member 11 of the present 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 damping panel 10. .. Further, as will be described in detail later, the stigma 13 of the vertical member 11 of the present embodiment is rotatably pin-bonded to the upper beam 32 in the in-plane direction of the vibration damping panel 10 and slides in the vertical direction. It is joined as possible. That is, in the present embodiment, the joint portion between the foundation beam 31 as the lower beam and the column base portion 12 and the joint portion between the upper beam 32 and the stigma 13 can rotate in the in-plane direction of the vibration damping panel 10. It is configured in. Here, the "in-plane direction of the vibration damping panel" means an arbitrary direction in the plane specified by the lower beam (foundation beam 31 in this embodiment) and the upper beam 32. The surface specified by the lower beam (foundation beam 31 in this embodiment) and the upper beam 32 is a vertical plane parallel to the extending direction of the lower beam (foundation beam 31 in this embodiment) and the upper beam 32.

The column base portion 12 is arranged above the top surface 31a of the foundation beam 31. As shown in FIG. 2, the column base portion 12 includes a flat plate-shaped top plate 14, a flat plate-shaped base plate 15, and a support frame 16 having a U-shaped cross section located between the top plate 14 and the base plate 15. Have. The column base portion 12 has a column base inner space 17 surrounded by a top plate 14, a base plate 15, and a support frame 16. In the space 17 inside the column base, a fastening member such as an upper end portion of the anchor bolt 35 and a nut 36 is arranged.

The top plate 14 and the base plate 15 can be, for example, a steel plate having a rectangular shape in a plan view when viewed from the axial direction of the vertical member 11. Here, FIG. 3 is a cross-sectional view taken along the line AA of FIG. In addition, in FIG. 3, the fastening member such as the nut 36 to be fastened to the anchor bolt 35 is omitted. As shown in FIG. 3, the base plate 15 is provided with a through hole 15a for passing a fastening member such as an anchor bolt 35. In this example, the through holes 15a located near the center of the base plate 15 are formed at only one place, 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 and 16c connected to 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 a fastening member such as a bolt or by welding.

The base plate 15 includes a lower surface 15b that constitutes the lower end surface of the column base portion 12. Here, as shown in FIG. 2, a spacer for forming a gap 43 below the column base portion 12 between the lower surface 15b of the base plate 15 of the column base portion 12 and the top surface 31a of the foundation beam 31. The member 41 is arranged. That is, the foundation beam 31 and the column base portion 12 of the present embodiment are joined via the spacer member 41 for forming the gap 43. The column base portion 12 can rotate in the in-plane direction of the vibration damping panel 10 with respect 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 portion 12 (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. The "left-right direction" means the horizontal direction in a plan view in the panel thickness direction orthogonal to the in-plane direction of the vibration damping panel 10.

The spacer member 41 has a smaller external dimension in the left-right direction than the base plate 15, whereby at least a gap 43 is formed in the left-right direction. The spacer member 41 of this example is a flat annular washer. As shown in FIG. 3, the diameter d (outer diameter) of the outer edge portion of the spacer member 41 is the width W (length in the left-right direction) and the depth D (length in the front-back direction perpendicular to the vertical direction and the left-right direction) of the base plate 15. Is smaller than that. The spacer member 41 has at least a smaller external dimension in the left-right direction than the base plate 15, and has a gap 43 that allows the vertical member 11 to swing in the in-plane direction of the vibration damping panel 10. In particular, its thickness and shape are not limited.

The column base portion 12 of this example is fastened to one anchor bolt 35 embedded in the foundation beam 31. That is, the column base portion 12 of the vertical member 11 of this example is swingably joined (pin-joined) to the foundation beam 31 by using only one anchor bolt 35.

Here, for example, one column base portion 12 of the vertical member 11 is provided with respect to the foundation beam 31 so that the spacer member 41 is not arranged between the column base portion 12 and the foundation beam 31, that is, the gap 43 is not formed. When joined using anchor bolts 35 (for example, semi-rigid joint or rigid joint), the degree of fixation of the column base 12 to the foundation beam 31 is compared with the degree of fixation of the upper beam 32 and the column head 13 which are pin-joined. Becomes too large. Therefore, for example, in the event of a large earthquake, stress may be concentrated on either the left or right flange portion 16b or 16c of the support frame 16 of the column base portion 12, and buckling deformation may occur in the flange portions 16b, 16c. On the other hand, in the vibration damping panel 10 of the present embodiment, the column base portion 12 and the foundation beam are formed in a state where the spacer member 41 is arranged between the column base portion 12 and the foundation beam 31 to form a gap 43. By joining (pin joining) the 31s, it becomes difficult for stress to concentrate on the support frame 16 of the column base portion 12, and buckling deformation of the flange portions 16b and 16c can be suppressed. The details of joining the upper beam 32 and the stigma 13 in this embodiment will be described later.

The vibration damping panel 10 of this example is provided with a twist suppressing member 50 capable of connecting the vertical members 11 to each other at a position different from that of the vibration damping device 20 and suppressing the twist of the vertical members 11. As shown in FIGS. Is fixed using. In this example, twist suppressing members 50 are provided at the upper and lower portions of the two vertical members 11, respectively. Specifically, the upper twist suppressing member 50 is located above the device fixing portion 11c, and the lower twist suppressing member 50 is located below the device fixing portion 11c. Note that FIG. 6 shows a cross section of the vibration damping panel 10 along the line CC of FIG. 1, but the description of the column base portion 12, the foundation beam 31, the spacer member 41, the reinforcing plate 42, etc. is omitted. There is.

The twist suppressing member 50 of this example is a plate-shaped member having a bent portion 51, and when a relative axial displacement occurs between the two vertical members 11, the bent portion 51 corresponds to the displacement. It is configured to elastically deform from the starting point. The bent portion 51 is located at the center of the rectangular twist suppressing member 50 in the longitudinal direction. Further, mounting portions 52 for fixing to the side surface 11b of the vertical member 11 are provided at both ends of the twist suppressing member 50 in the longitudinal direction. By fastening the mounting portion 52 to the side surface 11b using a fastening member such as a bolt in a state where each mounting portion 52 is in contact with the side surface 11b of the vertical member 11, the twist suppressing member 50 is attached to the two vertical members. It can be installed across 11 spaces. The twist suppressing member 50 may have a gently curved portion instead of the bent portion 51. Further, the twist suppressing member 50 does not have to have the bent portion 51. Further, the twist suppressing member 50 may have a plurality of bent portions 51 and / or curved portions.

Further, the plate-shaped twist suppressing member 50 is provided so that the direction in which the vertical member 11 is twisted and the direction of the strong axis of the twist suppressing member 50 are aligned with each other. Specifically, in the plate-shaped twist suppressing member 50 of the present embodiment, the in-plane direction as the direction of the strong axis is the direction in which the vertical member 11 is twisted, and the axis rotation about the vertical member 11 as the central axis. It is provided so that it aligns with the direction. By doing so, by specializing the twist suppressing member 50 for the twist suppressing function, it is possible to suppress the complicated design of the vibration damping panel 10.

More specifically, the twist suppressing member 50 is attached between the two vertical members 11 so that the front surface or the back surface faces upward or downward. That is, the twist suppressing member 50 extends in the depth direction of the vibration damping panel 10. Further, the upper twist suppressing member 50 and the lower twist suppressing member 50 have the same shape and are attached in an upside down state. As a result, the upper twist suppressing member 50 is arranged so that the bent portion 51 is convex downward, and the lower twist suppressing member 50 is arranged so that the bent portion 51 is convex upward.

The twist suppressing member 50 of this example can be formed by bending a rectangular flat plate-shaped steel material at the positions of the bent portion 51 and the mounting portion 52, and by making a hole in the mounting portion 52 for passing a bolt. .. The twist suppressing member 50 can be a so-called "rolling material" that has a pre-bent or curved portion and can be elastically deformed so as to be flat when a force is applied. The twist suppressing member 50 may have a flat plate shape having no bent portion 51 or the like.

Here, when the column base portion 12 is joined to the foundation beam 31 using only one anchor bolt 35 as in the present embodiment, for example, the shaft is attached to the vertical member 11 due to vibration caused by a large number of earthquakes. There is a possibility that rotation (rotation around the anchor bolt 35) will gradually occur. In that case, the vibration damping device 20 connected between the two vertical members 11 may be bent and deformed out of the plane, and may be easily broken at an early stage. On the other hand, in the present embodiment, by providing the twist suppressing member 50 for connecting the two vertical members 11, the axial rotation of the vertical members 11 can be suppressed. As a result, it is possible to prevent the vibration damping device 20 from being deformed by out-of-plane bending and breaking at an early stage.

In this example, a flat plate-shaped reinforcing plate 42 is arranged between the spacer member 41 and the top surface 31a of the foundation beam 31. As shown in FIGS. 2 and 3, the reinforcing plate 42 can be a rectangular flat plate-shaped 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 arranged 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 an indispensable configuration, and the spacer member 41 may be arranged directly on the top surface 31a of the foundation beam 31.

The stigma 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. Further, the stigma 13 is slidably joined to the upper beam 32 in the vertical direction. As a result, the vertical member 11 is joined in a state where the horizontal force is transmitted to the upper beam 32 at the upper end thereof and the vertical force and the moment are hardly transmitted at all.

FIG. 4 is an enlarged side view showing the stigma 13. The stigma 13 has a flat plate-shaped mounting piece 13a fixed to the upper end of the columnar main body portion 11a by means such as welding, and a flat plate-shaped pillar-side joining piece 13b fixed to the mounting piece 13a by means such as welding. Have. The column-side joint piece 13b is arranged perpendicular to the mounting piece 13a. The column-side joint piece 13b is formed with an elongated 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 (vertical direction) and has a dimension that allows a slight clearance between the through hole and the bolt to be inserted in the horizontal direction (horizontal direction).

A restraining member 33 is provided on the lower flange 32a of the upper beam 32. The restraint member 33 has a flat plate-shaped mounting piece 33a and a flat plate-shaped beam-side joint piece 33b fixed to the mounting piece 33a by means such as welding. The mounting piece 33a is formed with a hole through which a bolt is inserted, and is fixed to the lower flange 32a of the upper beam 32 by using a fastening member such as a bolt and a nut.

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 restraint member 33 is previously fixed to the lower flange 32a of the upper beam 32 by fastening members such as bolts and nuts, and the stigma 13 is joined to the restraint member 33 to form a vertical roller joint portion. .. The beam-side joint piece 33b of the restraint member 33 is arranged so as to hang down from the upper beam 32, and the column-side joint piece 13b of the stigma 13 is arranged in an upright state from the upper end of the columnar main body portion 11a. When the vertical member 11 is installed between the foundation beam 31 and the upper beam 32, the column base portion is in a state where the beam side joint piece 33b and the column side joint piece 13b are adjacent to each other so as to be parallel to each other. After joining 12 to the foundation beam 31, the stigma 13 is joined to the upper beam 32. When joining the stigma 13 to the upper beam 32, the bolt 37 as a pin member is inserted into the through hole 33c of the restraining member 33 and the through hole 13c of the stigma 13 to screw the nut. That is, by using the bolt 37 as the pin member, the stigma 13 is rotatably pin-joined to the upper beam 32 in the in-plane direction of the vibration damping panel 10. Further, by making the through hole 13c a long hole long in the vertical direction, the stigma 13 is slidably joined to the upper beam 32 in the vertical direction. In this way, the vertical member 11 can be joined to the upper beam 32 at its upper end 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 in a state where the horizontal force is transmitted to the upper beam 32 at the upper end thereof and the vertical force and the moment are hardly transmitted at all. Since the joining method for the upper beam 32 of the vertical member 11 is set in relation to the joining method for the foundation beam 31 as the lower beam of the vertical member 11, the configuration is not limited to the configuration that can rotate in the in-plane direction. , It is not limited to the configuration that can slide in the vertical direction. However, as in the present embodiment, the vertical member 11 is joined to the upper beam 32 at the upper end thereof so as to be rotatable in the in-plane direction of the vibration damping panel 10 and slidable in the vertical direction to cause an earthquake. Since the vertical force and bending moment are not sometimes applied from the vibration damping panel 10 to the upper beam 32, the structural design including the design of the upper beam 32 becomes easy. Further, in this example, the through hole 13c of the stigma 13 is an elongated hole, and the through hole 33c of the beam-side joint piece 33b is circular, but the present invention is not limited to this, and for example, the through hole 13c of the stigma 13 is circular. 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 a long hole.

As described above, in the present embodiment, the joint portion between the stigma 13 of the vertical member 11 and the upper beam 32 and the joint portion between the column base portion 12 of the vertical member 11 and the foundation beam 31 are the vibration damping panel 10. It is configured to be rotatable in the in-plane direction. Therefore, there is a difference between the degree of fixation of the stigma 13 to the upper beam 32 and the degree of fixation of the column base 12 to the foundation beam 31 as compared with the case where both joints are, for example, a combination of rigid joint and pin joint. It becomes smaller, and when the interlayer displacement occurs due to an earthquake or the like, the vertical member 11 is less likely to be bent and deformed. As a result, the plurality of vibration damping devices 20 can evenly bear the seismic force, so that the variation in life can be reduced, and as a result, the life of the vibration damping panel 10 can be extended.

The reverse may be true. That is, a pin member may be used at the joint portion between the column base portion 12 and the foundation beam 31, and a spacer member may be used at the joint portion between the stigma 13 and the upper beam 32. Further, a spacer member may be used for both joints, or a pin member may be used for both joints. However, from the viewpoint of workability, as in the present embodiment, a spacer member 41 is used at the joint between the column base 12 and the foundation beam 31, and a bolt 37 or the like is used at the joint between the capital 13 and the upper beam 32. It is preferable to use a pin member. By doing so, it becomes easy to construct the vibration damping panel 10.

As described above, the vibration damping panel 10 of the present embodiment is a vibration damping panel 10 installed between the lower beam (foundation beam 31) and the upper beam 32 of the building 1, and is arranged at a distance from each other.

With such a configuration, the difference between the degree of fixation of the column base 12 with respect to the foundation beam 31 and the degree of fixation of the capital 13 with respect to the upper beam 32 becomes small, and bending deformation of the vertical member 11 is less likely to occur. As a result, the plurality of vibration damping devices 20 can evenly bear the seismic force, so that the variation in life can be reduced and the life of the vibration damping panel 10 can be extended.

In the vibration damping panel 10 of the present embodiment, a flat plate-shaped reinforcing plate 42 is arranged between the spacer member 41 and the top surface 31a of the foundation beam 31. With such a configuration, the top surface 31a of the foundation beam 31 can be reinforced. Therefore, for example, it is possible to reliably prevent the spacer member 41 from coming into contact with the top surface 31a of the foundation beam 31 and causing damage.

Further, in the vibration damping panel 10 of the present embodiment, the column base portion 12 has a flat base plate 15 constituting the lower surface 15b of the column base portion 12, and the spacer member 41 is in the left-right direction with respect to the base plate 15. The external dimensions of are small. With such a configuration, the vertical member 11 can be easily swung in the left-right direction.

Further, in the vibration damping panel 10 of the present embodiment, the lower beam is composed of the foundation beam 31, and the column base portion 12 is fastened to one anchor bolt 35 embedded in the foundation beam 31. .. With such a configuration, the vertical member 11 can be easily swung as compared with the case where a plurality of anchor bolts 35 are used, and the anchor bolts 35 interfere with the reinforcing bars (not shown) inside the foundation beam 31. It becomes difficult to do.

Further, in the vibration damping panel 10 of the present embodiment, a twist suppressing member 50 capable of connecting a pair of vertical members 11 at a position different from that of the vibration damping device 20 and suppressing the twist of the pair of vertical members 11 is provided. Has been done. With such a configuration, it is possible to suppress the rotation of the vertical member 11 around the anchor bolt 35. As a result, the vibration damping device 20 is less likely to undergo out-of-plane bending deformation, so that the life of the vibration damping device 20 can be further extended.

Further, in the vibration damping panel 10 of the present embodiment, the twist suppressing member 50 is a plate-shaped member having a bent portion 51 or a bent portion, and is a relative axial displacement between the pair of vertical members 11. It is preferable that the bending portion 51 or the bending portion is elastically deformed from the bending portion 51 or the bending portion according to the displacement when the above occurs. With such a configuration, while the twist suppressing effect of the vertical member 11 is obtained by the twist suppressing member 50, the twist suppressing member 50 is less likely to be damaged or plastically deformed at the time of in-plane deformation between the pair of vertical members 11.

Further, in the vibration damping panel 10 of the present embodiment, twist suppressing members 50 are provided on the upper portion and the lower portion of the pair of vertical members 11, respectively. With such a configuration, the vertical member 11 is less likely to be twisted, and the load on the vibration damping device 20 is further reduced.

The present invention is not limited to the configuration of the above-described embodiment, and can be realized by various configurations without departing from the contents described in the claims. For example, the vibration damping panel 10 of this example is formed so as to be symmetrical as a whole, but the present invention is not limited to this, and the vibration damping panel 10 may be asymmetrical.
