Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damping damper that can improve the livability of a building in strong winds.

  In recent years, high-strength concrete has been put into practical use, and in addition to steel structures, demand for super-high-rise buildings and reinforced concrete buildings with a large tower-to-ratio ratio has increased. There is an urgent need to reduce minute amplitude vibrations. In order to cope with such a flow, a viscoelastic damper made of a viscoelastic body having a predetermined thickness (usually 5 mm or more) is incorporated into a building, and the viscoelastic body exerts a viscous resistance force proportional to the speed. It has been conventional to reduce the vibration of a building.

  However, since the viscoelastic damper has the property that its damping force increases in proportion to the amplitude, if this viscoelastic damper is used alone, the building will be damaged if an excessive external force acts on the building due to a large earthquake or the like. Large amplitude vibrations may occur, damaging the viscoelastic damper and causing malfunction.

  Therefore, as disclosed in Patent Document 1 or the like, by using a seismic damper unit in which a laminate of a friction material and a viscoelastic material is sandwiched between a pair of steel plates and bolted, the friction material slides during a large earthquake. A technique for maintaining the damper function of the viscoelastic material (hereinafter referred to as known technique 1) has been proposed.

Further, as disclosed in Patent Document 2, etc., a brace member in which a viscoelastic damper and a preceding yield member are combined is employed, and the viscoelastic damper is plastically deformed before the damper is broken, thereby providing viscoelasticity. There is also known a technique for preventing breakage of a damper (hereinafter, known technique 2).
JP-A-64-1877 (Claims, FIGS. 1-3) JP-A-10-37515 (paragraphs [0008] and [0009], FIG. 1)

  However, the earthquake-resistant damper unit of the prior art 1 has a structure in which a friction material is sandwiched between steel plates together with a viscoelastic material and tightened with bolts, and compressive force is inevitably applied to the viscoelastic material. Therefore, when evaluating the shear spring performance of the viscoelastic material, in addition to grasping the shearing behavior of the viscoelastic material at the time of compressive stress, long-term changes in the bolt axial force and the compression rigidity of the viscoelastic material, In other words, it is necessary to clarify even the creep phenomenon. In addition, since the friction surface of the seismic damper unit is formed of a horizontal surface, it is necessary to construct a plane outside the surface, which complicates the configuration of the friction surface. Therefore, the use of the seismic damper unit had to be complicated, and the practicality was still poor.

  Further, since the viscoelastic damper of the prior art 2 is of a brace type in which tensile and compressive stresses act obliquely along the diagonal of the frame, the stress generated at the connecting portion increases. As a result, not only the degree of freedom of design is reduced, but also there is a problem that it cannot be easily attached to a reinforced concrete building. In addition, the brace-type visco-elastic damper mounted diagonally has the disadvantage that the larger the mounting angle (specifically, in proportion to the square of the cosine of the mounting angle), the lower the horizontal damping performance. I was

  Furthermore, in general, the damping performance of a viscoelastic damper is proportional to the value obtained by dividing the sticking area of the viscoelastic body by the thickness of the viscoelastic body, so that the viscoelastic body can cope with small and medium-scale earthquakes. In general, the thickness of the viscoelastic body must be increased to obtain a certain damping performance because the thickness is usually 5 mm or more. There was also a disadvantage.

  In view of these circumstances, the present invention can of course improve the livability of a building in strong winds by maintaining the function of the viscoelastic damper even when an excessive external force acts on the building during a large earthquake. It is easy to use and excellent in practicality, has a large degree of freedom in design and can be easily installed in reinforced concrete buildings, avoids a reduction in damping performance in the horizontal direction, and maintains a constant damping performance It is an object of the present invention to provide a damping damper corresponding to livability that can reduce the production cost and improve the economic efficiency.

  In order to solve the above-mentioned problem, first, according to the present invention, the space adjusting members (6A, 6B, 8A, 8B) are vertically provided on the upper and lower two beams (3A, 3B), respectively. And a visco-elastic damper (9) connected between the space adjustment members so as to be extendable and contractible in the horizontal direction, wherein the friction material is arranged so that the visco-elastic damper can slide in the horizontal direction. (4a) and a joining member (4b) are laminated, and a sliding joint (4) which is bolted and joined is provided separately on at least one connecting portion of the viscoelastic damper.

  Further, according to the present invention, a space adjusting member (6A, 6B, 8A, 8B) is vertically provided on one of the upper and lower two beams (3A, 3B), and the two beams are provided. A livability-adaptive vibration damper (1) in which a visco-elastic damper (9) is connected to the other and the space adjusting member so as to be able to expand and contract in the horizontal direction, so that the visco-elastic damper can slide in the horizontal direction. In addition, a sliding joint body (4) in which a friction material (4a) and a joining member (4b) are laminated and bolted is provided separately on at least one connecting portion of the viscoelastic damper. Things.

  Here, the number of viscoelastic dampers is not particularly limited, and may be one or two or more. Further, as typical examples of the space adjusting member, studs (8A, 8B) and wall-shaped members (6A, 6B) can be given.

  Further, according to the present invention, one end of the truss member (24) is fixed to one of the upper and lower two beams (3A, 3B), and the other of the two beams and the other beam are fixed to each other. A comfortable damping damper (1) in which a viscoelastic damper (9) is connected to the other end of the truss member so as to be able to expand and contract in the horizontal direction, wherein the viscoelastic damper can slide in the horizontal direction. As described above, the sliding joint body (4) in which the friction material (4a) and the joining member (4b) are laminated and bolted to each other is provided between the viscoelastic damper and the beam or between the viscoelastic damper and the truss member. And between them.

Further, the present invention described in claim 4 is characterized in that the friction surface of the sliding joint body (4) according to any one of claims 1 to 3 is a vertical surface.
According to a fifth aspect of the present invention, as the viscoelastic damper (9) according to any one of the first to fourth aspects, a viscoelastic body having a thickness of 2 mm or less absorbs energy by being sheared. Is adopted.

  Furthermore, in the present invention according to claim 6, a yield member (10, 11) is connected in parallel to the viscoelastic damper (9) according to any one of claims 1 to 5 and the sliding joint (4). It is characterized by the following. Representative examples of the yield member include a steel damper (10) and a reinforcing bar (11).

  According to the present invention as set forth in any one of claims 1 to 6, when an excessive external force acts on the building and a large vibration occurs, the joining member of the sliding joint is relatively moved prior to the expansion and contraction of the viscoelastic damper. The visco-elastic damper does not generate excessive stress due to the slippage, and maintains the function of the visco-elastic damper even if an external force acts on the building during a large earthquake. It is possible to provide a livability-adaptive vibration damper capable of enhancing livability.

  Moreover, since the sliding joint is separated from the viscoelastic damper structurally independently, even if the bolt is tightened to adjust the sliding characteristics of the sliding joint, a compressive force acts on the viscoelastic body of the viscoelastic damper. Therefore, the shear spring performance of the viscoelastic body can be easily evaluated by a known simple shearing behavior, so that the use of the damping damper corresponding to the livability is simplified, and the practicability thereof is improved.

  In addition, since the damping damper for comfortability is not a brace type but a column type or wall type truss type, the stress generated at the joint is small, the design flexibility is high, and at the same time it is easy to use in reinforced concrete buildings. Can be attached to Moreover, since the viscoelastic damper is mounted in the horizontal direction, its damping performance is exhibited 100% in the horizontal direction. Furthermore, since it is a passive type vibration damper corresponding to livability, no power is required and maintenance is easy.

  In addition, according to the third aspect of the present invention, since the viscoelastic damper and the sliding joint can be accommodated in the ceiling or the floor, a portion exposed to the indoor space is reduced, and the installation space is reduced. Becomes smaller. Moreover, since the truss member is only provided between the upper and lower beams and can be installed without closing the opening, desired lighting and a view can be obtained, and a comfortable indoor space can be configured. At this time, by providing a steady rest at the end of the truss member that is not fixed to the beam, the out-of-plane deformation of the truss member can be restrained. It is possible and preferable.

  Further, according to the present invention as set forth in claim 4, since the configuration of the friction material and the joining member of the sliding joined body is simplified, the use of the damping damper corresponding to the livability is further simplified, and its practicality is reduced. Improve more and more. According to the fifth aspect of the present invention, the viscoelastic damper is made compact without lowering its damping performance, so that the manufacturing cost is reduced and economical efficiency is improved while maintaining a constant damping performance. be able to.

  Furthermore, according to the present invention as set forth in claim 6, when a large external force acts on the building and a large vibration occurs, the viscoelastic damper function is maintained to improve the livability of the building in a strong wind. In addition to being able to increase, the yielding member yields and absorbs the hysteresis energy, so that it is possible to exhibit a vibration damping effect.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First embodiment>
1A and 1B are diagrams showing a first embodiment of a livability damping damper according to the present invention, in which FIG. 1A is a front view of the use state, FIG. 1B is a side view of the use state, and FIG. () Is an enlarged detailed view of a portion C in (b), and (d) is a model diagram thereof.

  As shown in FIG. 1, the livability damper 1 is incorporated in a steel-framed building or the like, and includes studs 8A, 8B suspended one by one on upper and lower two beams 3A, 3B. have. As shown in FIG. 1 (c), a viscoelastic damper 9 that absorbs energy by shearing deformation of a viscoelastic body 9a having a thickness of 2 mm or less is provided between these studs 8A and 8B so as to expand and contract in the horizontal direction. Are linked.

  Here, as for the connecting portion of the viscoelastic damper 9, the upper side (the stud 8A side) is a slip joint using the tightening force of the bolt and the nut, and the lower side (the stud 8B side) is a rigid joint. ing. That is, a T-shaped steel 7 is suspended by bolt bonding below the upper stud 8A, and a viscoelastic damper 9 is installed above the lower stud 8B. A sliding joint 4 is interposed between the T-shaped steel 7 and the viscoelastic damper 9 so as to be slidable in the horizontal direction. As shown in FIG. It has a structure in which a mold-type friction material 4a and a joining member 4b having a stainless steel plate welded to its surface are laminated and joined by bolts. Thereby, the sliding joint 4 is structurally separated from the viscoelastic damper 9 independently, and the friction surface of the sliding joint 4 is vertical.

  Since the building in which the livability damping damper 1 is incorporated has the above-described configuration, when a strong amplitude generates a small amplitude vibration in the building, the vibration energy is converted into the viscoelasticity of the livability damping damper 1. Since the damper 9 absorbs and reduces it, it is possible to enhance the livability of the building in a strong wind. Further, since the sliding joint 4 is provided on the upper connecting portion of the viscoelastic damper 9, when an excessive external force acts on the building due to a large earthquake or the like and large vibration occurs, the viscoelastic damper 9 is used. Prior to the expansion and contraction, the T-section steel 7 and the joining member 4b of the sliding joint 4 cause relative slip, so that excessive stress is not generated in the viscoelastic damper 9. As a result, even if the viscoelastic body 9a used for the viscoelastic damper 9 is as thin as 2 mm or less, the sliding joint 4 is so formed as to slide within a deformation range that the viscoelastic body 9a can follow. Is adjusted, there is no risk that the viscoelastic damper 9 will be damaged and malfunction if an excessive external force acts on the building during a large earthquake.

  Here, unlike the known technology 1 in which the steel damper is connected in series to the viscoelastic damper, the slippery joint 4 is separated from the viscoelastic damper 9 as being structurally independent from the viscoelastic damper 9. Even if the bolts are tightened to adjust the sliding characteristics (such as the coefficient of friction) of the sliding joint 4, no compressive force acts on the viscoelastic body 9a of the viscoelastic damper 9, and the shear spring performance of the viscoelastic body 9a Can be easily evaluated by a known simple shearing behavior. Moreover, since the friction surface of the sliding joint 4 is a vertical surface, the configuration of the sliding joint 4 is simpler than that of the prior art 1. Therefore, it is easy to use the damping damper 1 corresponding to livability, and its practicality is improved.

  Further, since the dampness damper 1 corresponding to the livability is a pillar type joined to the beams 3A, 3B via the studs 8A, 8B, unlike the known technique 2 of the brace type, the stress generated at the joint thereof is small. In addition, the degree of freedom in design is increased, and it can be easily attached to a reinforced concrete building. Moreover, since the viscoelastic damper 9 is mounted in the horizontal direction in the dampness damper 1 corresponding to the livability, unlike the known technique 2 of the brace type in which the damping performance in the horizontal direction is reduced, the damping performance of the viscoelastic damper 9 is horizontal. 100% in the direction. Furthermore, since the dampness damper 1 corresponding to livability is of a passive type, no power is required and maintenance is easy. In addition, the viscoelastic body 9a of the viscoelastic damper 9 has a thickness as small as 2 mm or less, and can provide a constant damping performance without increasing the affixing area. It is possible to reduce the manufacturing cost of the vibration damper 1 and improve the economic efficiency.

  In the above-described embodiment, a case has been described in which the studs 8A and 8B are used as the space adjusting members. However, a space adjusting member other than the studs 8A and 8B may be employed. Hereinafter, as a second embodiment, a case where the wall-shaped members 6A and 6B are used as the space adjustment member will be described.

<Second embodiment>
FIGS. 2A and 2B are diagrams showing a second embodiment of the comfort-adaptive vibration damper according to the present invention, wherein FIG. 2A is a use state diagram and FIG. 2B is a model diagram thereof.

  As shown in FIG. 2, the damper 1 for living comfort is incorporated in a building such as a reinforced concrete structure having a structural frame 5 composed of columns 2 and beams 3, and includes two upper and lower beams 3A, 3B. The wall-shaped members 6A and 6B are provided vertically one by one. Two viscoelastic dampers 9 that absorb energy by shearing deformation of a viscoelastic body having a thickness of 2 mm or less are connected between these wall-shaped members 6A and 6B so as to be able to expand and contract in the horizontal direction.

  Here, the connecting portions of the viscoelastic dampers 9 are respectively formed on the upper side (on the wall-shaped member 6A side) by sliding connection using the tightening force of bolts and nuts, and on the lower side (on the wall-shaped member 6B side). Is a rigid joint. That is, a T-section steel 7 is suspended by bolting below the upper wall-like member 6A, and two viscoelastic dampers 9 are installed above the lower wall-like member 6B. A sliding joint 4 is interposed between the T-shaped steel 7 and each viscoelastic damper 9 so as to be slidable in the horizontal direction. It has a structure in which a joining member to which a stainless steel plate is welded is laminated and bolted. Each sliding joint 4 is separated from each viscoelastic damper 9, and the friction surface of each sliding joint 4 is vertical.

  Since the building in which the livability-adaptive vibration damper 1 is incorporated has the above-described configuration, when a strong amplitude generates a vibration with a small amplitude in the building, the vibration energy is transmitted to each viscous damper 1 of the livability-adaptive vibration damper 1. Since the elastic damper 9 absorbs and reduces, the livability of the building at the time of strong wind can be improved. Further, since the sliding joints 4 are provided at the upper connecting portions of the viscoelastic dampers 9, respectively, when an excessive external force acts on the building due to a large earthquake or the like and a large vibration is generated, the respective viscoelasticity is increased. Prior to the expansion and contraction of the damper 9, the T-shaped steel 7 and the joining member of the sliding joint 4 cause relative sliding, so that no excessive stress is generated in each viscoelastic damper 9. As a result, even if the viscoelastic body used for each viscoelastic damper 9 is as thin as 2 mm or less, each of the sliding joints 4 is caused to slip within a deformation range that the viscoelastic body can follow. Is adjusted, there is no risk that the viscoelastic damper 9 will be damaged and malfunction if an excessive external force acts on the building during a large earthquake.

  Here, unlike the prior art 1 in which the steel damper is connected in series with the viscoelastic damper, the slippery joint 4 is separated from the viscoelastic damper 9, and thus the Even if the bolts are tightened to adjust the sliding characteristics (such as the coefficient of friction), no compressive force acts on the viscoelastic body 9 of the viscoelastic damper 9, and the shear spring performance of the viscoelastic body 9 is determined by a known simple shearing behavior. Can be easily evaluated. Moreover, since the friction surface of the sliding joint 4 is a vertical surface, the configuration of the sliding joint 4 is simpler than that of the prior art 1. Accordingly, the usage of the damping damper 1 corresponding to the livability is simplified, and its practicality is improved.

Moreover, since the dampness damper 1 for comfortability is a wall type joined to the beams 3A, 3B via the wall-shaped members 6A, 6B, unlike the known technique 2 of the brace type, the stress generated at the joint thereof is reduced. Because of its small size, it has a high degree of design freedom and can be easily mounted on reinforced concrete buildings. Moreover, since the viscoelastic damper 9 is mounted in the horizontal direction in the dampness damper 1 corresponding to the livability, unlike the known technique 2 of the brace type in which the damping performance in the horizontal direction is reduced, the damping performance of the viscoelastic damper 9 is horizontal. 100% in the direction. Furthermore, since the dampness damper 1 corresponding to livability is of a passive type, no power is required and maintenance is easy. In addition, the viscoelastic body of the viscoelastic damper 9 has a thickness as small as 2 mm or less, and can provide a constant damping performance without increasing the affixing area. It is possible to reduce the manufacturing cost of the vibration damper 1 and improve the economic efficiency.

  In the above-described embodiment, as shown in FIGS. 1 (d) and 2 (b), the habitability control system in which the sliding joint 4 and the viscoelastic damper 9 are merely connected to the lower side of the T-shaped steel 7 is shown. Although the vibration damper 1 has been described, a yield member such as a steel damper or a reinforcing bar may be connected in parallel to the sliding joint 4 and the viscoelastic damper 9. Hereinafter, a case where steel dampers are connected in parallel will be described as a third embodiment, and a case where reinforcing bars are connected in parallel will be described as a fourth embodiment.

<Third embodiment>
FIGS. 3A and 3B are diagrams showing a third embodiment of the damping damper corresponding to the habitability according to the present invention, wherein FIG. 3A is a use state diagram, and FIG. 3B is a model diagram thereof.

  As shown in FIG. 3, the livability damper 1 is incorporated in a building such as a reinforced concrete structure having a structural skeleton 5 composed of columns 2 and beams 3, and is provided under a T-shaped steel 7 as shown in FIG. The second embodiment is the same as the above-described second embodiment except that a steel damper 10 as a yielding member is rigidly connected in parallel with the sliding joint 4 and the viscoelastic damper 9.

  Therefore, when a vibration having a small amplitude is generated in the building due to the strong wind, the vibration energy is absorbed and reduced by the viscoelastic dampers 9 of the damping damper 1 corresponding to the livability, so that the livability of the building in a strong wind is enhanced. be able to. Further, since the sliding joints 4 are provided at the upper connecting portions of the viscoelastic dampers 9, respectively, when an excessive external force acts on the building due to a large earthquake or the like and a large vibration is generated, the respective viscoelasticity is increased. Since the damper 9 causes a relative slip prior to its expansion and contraction, no excessive stress is generated on the viscoelastic damper 9, and therefore even if an excessive external force acts on the building during a large earthquake, the viscoelastic damper 9 may be damaged. There is no worry that it will malfunction. At the same time, the steel material damper 10 yields and exhibits a vibration damping effect in a form absorbing the hysteretic energy.

<Fourth embodiment>
FIGS. 4A and 4B are diagrams showing a fourth embodiment of the comfort-adaptive vibration damper according to the present invention, wherein FIG. 4A is a use state diagram and FIG. 4B is a model diagram thereof.

  As shown in FIG. 4, the damping damper 1 for habitability is incorporated in a building such as a reinforced concrete structure having a structural frame 5 composed of columns 2 and beams 3, and includes a sliding joint 4 and a viscoelastic damper. 9 are reduced one by one, and a plurality of (16 in FIG. 4) rebars 11 as a yielding member are buried under the T-shaped steel 7 at both ends and sunk by being buried in the wall-shaped members 6A and 6B. It is the same as the above-described second embodiment except that the joint body 4 and the viscoelastic damper 9 are connected in parallel by a rigid joint.

  Therefore, when a small amplitude vibration is generated in the building due to the strong wind, the vibration energy is absorbed and reduced by the viscoelastic damper 9 of the dampness damper 1 corresponding to the livability. Can be. In addition, since the sliding joint 4 is provided at the upper connecting portion of the viscoelastic damper 9, when an excessive external force acts on this building due to a large earthquake or the like and a large vibration occurs, the viscoelastic damper 9 is moved. Since relative slip occurs prior to the expansion and contraction, excessive stress is not generated in the viscoelastic damper 9, and the viscoelastic damper 9 is damaged even when an excessive external force acts on the building during a large earthquake. There is no worry about failure. At the same time, the reinforcing bar 11 yields and absorbs the hysteretic energy, thereby exhibiting a vibration damping effect.

  In the above-described first to third embodiments, the livability-adaptive vibration damper 1 in which the sliding joint body 4 is provided at the upper connection portion of the viscoelastic damper 9 has been described. The sliding joint 4 may be provided at the connecting part on the side, or the sliding joint 4 may be provided at the connecting part on both the upper and lower sides of the viscoelastic damper 9.

  Further, in the above-described embodiment, the case where the space adjusting members (the studs 8A and 8B or the wall-shaped members 6A and 6B) are provided on the beams 3A and 3B, respectively, but one of the space adjusting members is omitted, and It is also possible to directly join the shape steel 7, the viscoelastic damper 9, and the yield member (steel damper 10 or reinforcing bar 11) to the beams 3A, 3B.

<Fifth embodiment>
FIG. 5 and FIG. 6 are views showing a fifth embodiment of the livability damper according to the present invention.
As shown in these figures, the livability damper 20 is incorporated in a steel-framed building. The outer frame 9b of the viscoelastic damper 9 is fixed to the lower surface of the upper beam 3A. I have. A plurality of (three in the figure) movable plates 9c are incorporated in the outer frame 9b via a viscoelastic body 9a having a thickness of 2 mm or less. As a result, the movable plate 9c is provided to be displaceable in the horizontal direction due to the shear deformation of the viscoelastic body 9a.

  The sliding joint 4 is connected to one end of the movable plate 9c. As shown in FIGS. 6A and 6C, the sliding joints 4 are disposed on both sides of the three movable plates 9c of the viscoelastic damper 9 and are integrally connected by high-strength bolts 21 or the like. Two joining members 4b, a substrate 4c disposed between the joining members 4b and having a stainless steel plate welded to a surface facing the joining member 4b, a stainless steel plate of the substrate 4c and the joining member 4b and a mold-based friction material 4a attached to the substrate 4c, and the substrate 4c is slidably provided on the joining member 4b by the friction material 4a. The board 4c, the friction material 4a, and the joining member 4b are sandwiched by two sets of pressing plates 4d and are connected by bolts 22.

Reference numeral 23 in the drawing denotes a long hole that allows the joining member 4b to slide in the horizontal direction when the bolt 22 is inserted through the substrate 4c. Thus, by adjusting the tightening force of the bolt 22, the force at the start of sliding of the joining member 4b, that is, the sliding characteristics of the sliding joint 4 can be arbitrarily set. With the above configuration, the sliding joint 4 is independent of the viscoelastic damper 9, and the friction surface of the sliding joint 4 is vertical.
The upper end of the truss member 24 erected on the lower beam 3B is integrally joined to the substrate 4c of the sliding joint body 4.

The truss member 24 is composed of a column 25 erected on the beam 3B and a brace 26 erected between the intersection of the column 2 and the beam 3B and the upper end of the column 25. The substrate 4c is fixed to the upper end of the substrate 25. Note that a gap is formed between the upper end of the support 25 and the upper beam 3A to allow relative displacement between the two.
Further, on both sides of the upper end of the column 25, a steady rest 27 attached to the lower flange of the beam 3B is provided.

According to the damping damper 20 having the above-described configuration, it is possible to obtain the same operation and effects as those described in the first and second embodiments.
In addition, since the viscoelastic damper 9 and the sliding joint 4 can be accommodated in the ceiling above the ceiling height indicated by L1 in the figure, the portion exposed to the indoor space is reduced, and the restriction on the installation space is reduced. Become.

Moreover, since only the truss member 24 is provided between the upper and lower beams 3A and 3B, the truss member 24 can be installed without closing the opening, so that it is possible to obtain a desired lighting and a view, thereby forming a comfortable indoor space. It is possible to do.
Further, since the steady rest 27 of the column 25 of the truss member 24 is provided on the upper beam 3A, out-of-plane deformation of the truss member 24 can be reliably restrained. For this reason, it is also possible to fix the lower end of the column 25 or the brace 26 to the beam 3B by pin bonding.

  In the fifth embodiment, only the case where the viscoelastic damper 9 and the sliding joint body 4 are provided on the lower surface side of the upper beam 3A has been described. However, the present invention is not limited to this case. The viscoelastic damper 9 and the sliding joint 4 are provided on the upper surface side of the beam 3B, and a truss member is vertically provided downward from the upper beam 3A to connect the lower end thereof to the sliding joint 4. It is. In this case, the viscoelastic damper 9 and the sliding joint 4 can be stored in the floor below the floor top level indicated by L2 in the figure. Further, even when the positional relationship between the viscoelastic damper 9 and the sliding joint 4 is reversed, the same operation and effect can be obtained.
