[0001]
BACKGROUND OF THE INVENTION
In the present invention, when a high-rise building is composed of at least two frames that are separated in a vertical direction and are juxtaposed (hereinafter referred to as a separated frame), vibration control is performed by connecting the separated frames of the building. It belongs to the technical field of connected vibration control devices.
[0002]
[Prior art]
Conventional vibration damping dampers generally exhibit damping performance on the premise that the entire building frame undergoes shear deformation, and cannot sufficiently exhibit vibration damping effects against the outstanding bending deformation of high-rise buildings.
[0003]
Therefore, conventionally, a vibration damper of a high-rise building that undergoes bending shear deformation has generally been implemented by a method of installing a mass damper at the top of the building. Although this method can control bending and shearing of high-rise buildings at the same time, it requires an unrealistic mass weight to improve the seismic safety of the building. In fact, it has been used to improve comfortability.

[Problems to be solved by the present invention]
The connection damping device of the above-described prior art (1) is configured to obtain a great damping effect by causing the damper to exhibit the damping performance by utilizing the difference in the vibration characteristics between the separated frames.
However, as the building becomes taller, the difference in vibration characteristics between the separated frames that make up the building becomes smaller, and the deformation (displacement difference) between the separated frames during an earthquake also becomes smaller. Resulting in.
[0007]
The conventional vibration damping device of the prior art (2) is similar in concept to the conventional vibration damping device of the prior art (1), but in the separated frame, only between the top portions where the greatest deformation is expected during an earthquake. It is set as the structure which connected. However, in this case, as the building becomes taller, the difference in vibration characteristics between the frames that make up the building becomes smaller, and the deformation (displacement difference) between the tops of the separated frames during an earthquake also becomes smaller. The reduction in vibration control performance is inevitable.
[0008]
Therefore, the object of the present invention is to control the vibration of the separated frame in the horizontal direction when the high-rise building is composed of at least two separated frames that are separated from each other in the vertical direction. The deformation is constrained and connected so as to allow vertical deformation, and the large bending deformation acting on the entire frame in the event of an earthquake is converted into large vertical deformation between the tops of the separation frame. The deformation in the vertical direction between the tops of the doors can be converted into the deformation of conventional dampers, so that the dampers can exert a great damping performance, resulting in a great vibration control effect for the entire building, and the seismic safety of the building It is an object of the present invention to provide a coupled vibration control device for a separated frame that can be improved.

Embodiments and Examples of the Invention
When the coupled vibration control device for a separated frame according to the inventions described in claims 1 to 6 is composed of at least two separated frames that are separated from each other in a vertical direction, the separated frames are coupled. It is suitably implemented as a connected vibration damping device that performs vibration damping control.
[0017]

[0018]
The principle of the coupled vibration damping device of the present invention is that the coupling mechanism 4 constrains deformation in the horizontal direction between the separating frames 1 and 2 and allows deformation in the vertical direction. In the meantime, as shown in FIG. 2 or 5, the bending deformation acting on the entire frame is converted into a large vertical deformation. Furthermore, since the damper mechanism 5 or 9 or 14 is functionally incorporated in the hat truss 3 corresponding to the respective deformation operation types, the damper mechanism 5 or 9 or 14 exhibits a large damping performance. As a result, the building as a whole has a great damping effect, and the building can be seismically safe.
[0019]
First, the details of the hat truss 3 with a damper among the above-described two components of the coupled vibration damping device of the present invention will be described.
Damper with hat Truss 3 illustrated in FIG. 1 is installed by connecting with by that hinged to the inner top and pins 6,6 of separation Frames 1 and 2. Furthermore between the hat truss 3 and the outer top of the separation Frames 1 and 2, it converts the vertical deformation generated between separating Frames 1 and 2 in the axial deformation, attenuated by utilizing the axial deformation, for example, oil dampers , the damper mechanism 5 consisting of a cylinder and a piston, such as Bingham damper, through the mounting member 3a and 3a, that is built is hingedly joined to the opposite ends by pins 7,7.
[0020]
Therefore, when vertical deformation accompanying bending shear deformation occurs at the top of the separated frames 1 and 2 due to the horizontal force at the time of the earthquake, as shown in FIG. 2, the damper provided between the hat truss 3 and each frame 1 and 2 The mechanism 5 undergoes a transformed axial deformation. Therefore, the damper mechanism 5 is actuated by the axial deformation, and the damping performance is exhibited.
[0021]
Damper with hat Truss 3 illustrated in FIG. 3 is installed in conjunction with the rotation damping mechanism 8 with the inner top and low yield point steels, lead, etc. separation Frames 1 and 2. Furthermore, between the hat truss and the outer top of the separating frames 1 and 2, the vertical deformation generated between the separating frames 1 and 2 is converted into axial deformation and bending deformation, and the axial deformation and bending deformation are utilized. A damper mechanism 9 using ultra-low yield point steel, lead, or the like that is damped is joined and incorporated in series via attachment members 3a and 3a .
[0022]
Therefore, when vertical deformation caused by bending shear deformation occurs at the top of the separated frames 1 and 2 due to the horizontal force at the time of the earthquake, the frame 1 and 2 are deformed as shown in FIG. 2 as in the embodiment of FIG. Then, the converted shaft deformation and bending deformation are generated in the damper mechanism 9 provided between the hat truss 3 and each of the frames 1 and 2. Therefore, the damper mechanism 9 operates by the axial deformation and bending deformation, and the damping performance is exhibited. The hat truss 3 in the same embodiment is joined by the rotation damping mechanisms 8 and 8 corresponding to the joining by the pins 6 and 6 in the embodiment of FIG. Converts the vertical deformation of the material into rotational deformation and exhibits a certain level of damping performance.
[0023]
The hat truss 3 with a damper illustrated in FIG. 4 is installed as a parallel link mechanism that converts vertical deformation generated between the separation frames 1 and 2 into parallel motion. That is, the extension members 10 and 10 of the frames 1 and 2 and the upper and lower horizontal links 11 and 12 of the parallel link mechanism are connected by the pins 13 to form a parallelogram. In the case of the illustrated example, a viscous wall damper 14 is incorporated between the horizontal links 11 and 12 that perform parallel movement in the vertical direction as a damper mechanism that damps using the relative parallel movement of both. Outer-walled container 14a in the viscous body wall damper 14 is fixed to the horizontal link 12 of the lower, upper end of the inner resistive plate 14b is that is fixed to the upper horizontal link 11.
[0024]
Therefore, when vertical deformation accompanying bending shear deformation occurs at the tops of the separating frames 1 and 2 due to the horizontal force at the time of the earthquake, the vertical horizontal links 11 of the parallel link mechanism installed as the hat truss 3 as shown in FIG. , 12 produces a transformed horizontal deformation. Accordingly, the viscous wall damper 14 is actuated by the relative horizontal deformation between the upper and lower horizontal links 11 and 12, and the damping performance is exhibited.

Next, the detail of the connection mechanism 4 which is another component of the connection damping device of this invention is demonstrated.

[0027]
Therefore, when a bending shear deformation occurs between the separated frames 1 and 2 due to the horizontal force at the time of the earthquake, the horizontal direction between the frames 1 and 2 at the portions of the pins 17 and 17 between the mounting members 15 and 15 and the connecting member 16. Deformation is restricted, and deformation in the vertical direction is allowed by its rotation (bending).
[0028]
7A and 7B, in the connecting mechanism 4 illustrated in FIGS. 7A and 7B, the H-shaped steel (H-shaped connecting member) 18 straddles the flange portions 18a and 18a in the pillars (casings) 1A and 2A of the adjacent portions of the separating frames 1 and 2. It incorporated vertically in the arrangement, the pillar 1A, Ru configuration der viscoelastic body 19 in a movable range of the contact surface and the vertical is interposed between 2A and H-beam 18.
[0029]
Therefore, when bending shear deformation occurs between the separated frames 1 and 2 due to the horizontal force at the time of the earthquake, each flange portion of the H-shaped steel 18 is locked inside the columns 1A and 2A, and the horizontal direction between the frames 1 and 2 Deformation in the vertical direction is restricted, and deformation in the vertical direction is allowed while receiving a viscous resistance by the viscoelastic body 19 inside the columns 1A and 2A and exhibiting a certain level of damping performance.
[0030]
In the coupling mechanism 4 illustrated in FIGS. 8A and 8B, columns (vertical members) 1 </ b> A and 2 </ b> A of adjacent portions of the separation frames 1 and 2 are surrounded by a common steel pipe (tubular member) 20. In the embodiment, the two pillars 1A, 2A and the steel pipe 20, that is slidably contact via the mating member 22 of the sliding member 21 and the stainless steel plate such as PTFE resin.
[0031]
Therefore, when bending shear deformation occurs between the separated frames 1 and 2 due to the horizontal force at the time of the earthquake, both the pillars 1A and 2A are pressed down by the steel pipe 20, and the horizontal deformation between the frames 1 and 2 is restrained. The deformation in the vertical direction is allowed by the action of the sliding material 21 and the mating material 22.
[0032]
Finally, FIGS. 9A to 9C show the results of the seismic response analysis of the separated frame (maximum response acceleration, maximum layer shear force, maximum tipping moment at each floor of the building during the earthquake). (A) is a case without a connection damping device, (b), (c), (d) is a case with the connection damping device of the present invention. However, the damping performance of the damper incorporated in the order of (b), (c), and (d) is increased. As is clear from these graphs, it is understood that the response characteristics (b), (c), and (d) of the present invention can reduce the seismic response by 20 to 30% compared to the conventional response characteristics (a). The
