Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration control structure for a building. This damping structure can be applied to both existing and new buildings.

[0002]

2. Description of the Related Art A frame structure comprising upper and lower beams and left and right columns disposed between the upper and lower beams, that is, a plurality of stiffening panels disposed between upper and lower beams of the shaft portion or between left and right columns,
There has been proposed an energy absorber of a frame body which is provided with a plastic body disposed between the stiffening panels, and which is formed so that the plastic body yields due to a predetermined or more external force acting on the frame body and is plastically deformed ( JP-A-6-330653).

[0003]

When a horizontal load due to an earthquake is applied to a building, the upper end of the column or the beam connected to the column is displaced by a certain distance in the horizontal direction with respect to the lower end of the column. Therefore, it is preferable to increase the amount of deformation of the plastic body with respect to the amount of displacement in order to efficiently perform energy absorption.However, according to the above proposal, the amount of deformation of the plastic body is increased, and No specific measures to increase the size are described.

The present invention provides a damping structure for a building in which the amount of deformation of the damper means with respect to the amount of displacement when a horizontal load due to an earthquake is applied to the building is increased, whereby the seismic energy can be efficiently absorbed.

[0005]

SUMMARY OF THE INVENTION The present invention is a vibration control structure for a building comprising a first column, a second column, and an upper beam coupled to the first column. A first auxiliary frame, a second auxiliary frame, and damper means are provided. The first auxiliary frame is coupled to the first column or the beam so as to take out a horizontal displacement of a coupling portion between the first column and the beam as a vertical displacement, and the first column. And an imaginary plane including the axis of each of the second columns or a plane substantially parallel thereto, and extends toward the second columns. The second auxiliary frame includes the second auxiliary frame.
In order to take out the horizontal displacement of the joint between the column and the beam as the vertical displacement, the first column is coupled to the second column or the beam, and the first surface is formed on the virtual plane or a plane substantially parallel to the virtual plane. And is horizontally spaced from the first auxiliary frame. The damper means is disposed within the space and is attached to each of the first auxiliary frame and the second auxiliary frame. The sum of the projection length of the first auxiliary frame on the horizontal plane and the projection length of the second auxiliary frame on the horizontal plane,
The ratio of the height from the lower end surface of the first column to the lower surface of the beam is set to be greater than 1.

When a horizontal load due to an earthquake is applied to a building,
The beam is displaced horizontally with respect to the lower ends of the first and second columns, and the first and second columns are deformed. As a result, the mutually opposing ends of the first auxiliary frame and the second auxiliary frame are displaced in the vertical direction, thereby deforming the damper means.

When a horizontal load due to an earthquake is applied, the building shakes so that the whole building is displaced together in one horizontal direction and the other. At this time, since the first auxiliary frame extends toward the second column and the second auxiliary frame extends toward the first column, the first auxiliary frame and the second auxiliary frame are mutually extended. The opposite end is displaced in the opposite direction. This is the ratio of the sum of the projected length of the first auxiliary frame to the horizontal plane and the projected length of the second auxiliary frame to the horizontal plane, relative to the height from the lower end surface of the first column to the lower surface of the beam. Is greater than 1, the amount of deformation applied to the damper means is greater than the amount of displacement of the beam. In other words, the damper means is subjected to a deformation amount in which the displacement amount of the beam is enlarged, so that the damper means can be sufficiently deformed and efficiently absorb the seismic energy. This also makes it possible to reduce the number of damper means, and to exert a vibration damping effect even with a small displacement. Furthermore, when an existing building has a vibration control effect, a large vibration control effect can be expected with a relatively small shaft portion.

[0008] The present invention is also a vibration control structure of a building including a first column and a second column, and includes a first auxiliary frame, a second auxiliary frame, and damper means. The first auxiliary frame is coupled to the first column and includes at least two members. One end of each of the at least two members is vertically coupled to the first column at a predetermined distance, and the other ends of the at least two members are respectively connected to the first column and the second column. And extends toward the second column in a virtual plane including the axis of, or a plane substantially parallel thereto, and is connected to each other. The second auxiliary frame is coupled to the second column and includes at least two members. One end of the at least two members is vertically coupled to the second column at the predetermined distance, and the other end of the at least two members is connected to the virtual plane or a plane substantially parallel thereto. Extending in a plane toward the first post, coupled to each other, and spaced horizontally from the first auxiliary frame. The damper means is disposed within the space, and is attached to the first auxiliary frame and the second auxiliary frame, respectively. The ratio of the sum of the projection length of the first auxiliary frame to the horizontal plane and the projection length of the second auxiliary frame to the horizontal plane is set to be larger than 1 for the predetermined distance.

When the first auxiliary frame and the second auxiliary frame each include at least two members, the present invention can also include a first vertical auxiliary frame and a second vertical auxiliary frame. The first vertical auxiliary frame is arranged along the first column outside or inside the building, and is fixed to the first column. The second vertical auxiliary frame is arranged along the second column outside or inside the building, and is fixed to the second column. The first auxiliary frame is connected to the first vertical auxiliary frame, and the second auxiliary frame is connected to the second vertical auxiliary frame.

According to the second and third aspects of the present invention, when a horizontal load due to an earthquake is applied to the building, the upper connecting portion of the first auxiliary frame with the first column or the first vertical auxiliary frame. And the upper joint of the second auxiliary frame with the second column or the second vertical auxiliary frame is displaced horizontally with respect to the respective lower joint, and the first column or the first column is displaced horizontally. The vertical auxiliary frame and the second pillar or the second vertical auxiliary frame are deformed. As a result, the mutually opposing ends of the first auxiliary frame and the second auxiliary frame are displaced in the vertical direction, thereby deforming the damper means.

When a horizontal load due to an earthquake is applied, the building is shaken so that the entire building is displaced together in one horizontal direction and the other. At this time, the first auxiliary frame extends toward the second column or the second vertical auxiliary frame, and the second auxiliary frame extends toward the first column or the first vertical auxiliary frame. Opposite ends of the first auxiliary frame and the second auxiliary frame are displaced in opposite directions. At least 2 of the sum of the projection length of the first auxiliary frame on the horizontal plane and the projection length of the second auxiliary frame on the horizontal plane,
Since the ratio of one end of each of the two members to the predetermined distance in the vertical direction is greater than 1, the amount of deformation applied to the damper means is, for example, between the first column of the first auxiliary frame or the first vertical auxiliary frame. It becomes larger than the displacement of the upper joint. Thus, the same effect as the first aspect can be obtained.

[0012]

Is horizontally spaced from the head. In the embodiment shown, the second auxiliary frame 22 is the first auxiliary frame 20.
It has the same shape and size as above, but this is not essential as will be apparent from the description below.

The damper means 24 includes a first auxiliary frame 2
0 and the second auxiliary frame 22 are disposed within the interval between the first auxiliary frame 20 and the second auxiliary frame 22.
And attached to each. In the illustrated embodiment,
The damper means 24 has a form in which a plurality of slits 46 are opened in a steel plate, and the slits 46 are arranged so as to be horizontal, and the flanges 47 at both ends are connected to the first and second auxiliary frames 20 and 20.
22 and welded or bolted. The damper means 24 can be elastically deformed by the elasticity of the plate portion between the slits 46, 46, and can be plastically deformed when its elastic limit is exceeded. The limit between the elastic deformation and the plastic deformation can be adjusted by the number of the slits 46, the width of the plate portion between the slits, and the like.

The first auxiliary frame 20 and the second auxiliary frame 22 are defined by the sum of the projection length of the first auxiliary frame 20 on the horizontal plane and the projection length of the second auxiliary frame 22 on the horizontal plane. It is formed so that the ratio of the height from the lower end surface of the first pillar 10 or the second pillar 12 to the lower surface of the beam 14 is greater than one. In the embodiment shown, the beam 1 is
6, the height is the distance from the upper surface of the lower beam 16 to the lower surface of the upper beam 14.

When a horizontal load of an earthquake is applied to the building, the shaft 1
8 is displaced or deformed as shown by a solid line from a normal position shown by a virtual line in FIG. That is, the upper beam 14 is the lower end of the first and second columns 10 and 12 or the lower beam 16.
, The first column 10 and the second column 12 are deformed. However, the first auxiliary frame 20 and the second auxiliary frame 22 are displaced with the deformation of the first column 10 and the second column 12, respectively, without being substantially deformed.
As a result, when the upper beam 14 is displaced rightward, the first auxiliary frame 20 is displaced downward, and the second auxiliary frame 2 is displaced downward.
2 is displaced upward to deform the damper member 24. Conversely, when the upper beam 14 is displaced leftward, the first auxiliary frame 20 is displaced upward, and the second auxiliary frame 22 is displaced downward to deform the damper member 24.

As shown in FIG. 3, the first auxiliary frame 2
0, the member 28 of the second auxiliary frame 22, the actual length of the member 38 is L ₁ , L ₂ , and the angle between the member 28 and the horizontal plane is Φ ₁ ,
Φ ₂ , the projected length in the horizontal direction is l ₁ , l ₂ , the height from the upper surface of the lower beam to the lower surface of the upper beam is h, and the horizontal displacement of the upper beam is δ , The deformation angles of the columns 10 and 12 are θ, the downward displacement of the first auxiliary frame 20 is X ₁ , and the upward displacement of the second auxiliary frame 22 is X _2.
And

As described above, the sum of the projection length of the first auxiliary frame 20 on the horizontal plane and the projection length of the second auxiliary frame 22 on the horizontal plane is obtained from the upper surface of the lower beam 16 to the upper beam 14. Since the ratio of the height to the lower surface is larger than 1, (l ₁ + l ₂ ) / h> 1. The downward displacement X _{1 of} the first auxiliary frame 20
X ₁ = L ₁ sinΦ ₁ −L ₁ sin (Φ ₁ −θ) Upward displacement X _{2 of} the second auxiliary frame 22
X ₂ = L ₂ sin (Φ ₂ + θ) −L ₂ sinΦ ₂ Here, δ = htan θ, for example, h
Is 250 cm 2, δ is about 1 cm 2, and θ is very small, so that tan θ ≒ θ can be satisfied, and θ can be constant. Accordingly, the trigonometric functions [Phi ₁ of the second term of the formula, also when Taylor expansion about ₂ trigonometric functions [Phi of the first term of the _{equation, sin (Φ 1 -θ) =} sin Φ 1 + {(- θ) / 1! _{} Cos Φ 1 + {(-} θ) 2/2! } - (! Θ / 1) (sin Φ 1) + ···· sin (Φ 2 + θ) = sin Φ 2 + cos Φ 2 + (θ 2/2!) (- sin Φ 2) + ···・ It becomes. In the formula and the formula, θ≪1, | sin Φ ₁ |
Since ≦ 1 and | sin Φ ₂ | ≦ 1, the third term has a very small value as compared with 1, and can be omitted. Therefore, sin (Φ ₁ −θ) ≒ sin Φ ₁ + (−θ) / 1! _{} Cos Φ 1 = sin Φ 1} -θcos Φ 1 is _{'sin (Φ 2 + θ)} ≒ s in Φ 2 + (θ / 1!) Cos Φ 2 = s in Φ 2 + θcos Φ 2' is obtained. Therefore, from the equation and 'formula, and _{X 1 = L 1 θcos Φ 1} = l 1 θ. Also, from the equation and 'formula, and _{X 2 = L 2 θcos Φ 2} = l 2 θ. When l ₁ , l ₂ , and h are eliminated and rearranged from the equation, the equation, and the above-mentioned δ ≒ hθ, X ₁ + X ₂ > δ is obtained. This is because (l ₁ + l ₂ ) / h> 1, that is, the sum of the projection length of the first auxiliary frame on the horizontal plane and the projection length of the second auxiliary frame on the horizontal plane is obtained from the upper surface of the lower beam. By setting the ratio of the height of the upper beam to the lower surface to be greater than 1, the amount of vertical displacement of the first and second auxiliary frames is made larger than the amount of horizontal displacement of the upper beam. Indicates that you can do it.

In the above equation, L ₁ , L ₂ , Φ ₁ , Φ
_{Numeral 2} denotes the actual length and the angle from the horizontal plane of the member 28 of the first auxiliary frame 20 and the member 38 of the second auxiliary frame 22, but this actual length and angle do not appear in the formula. This indicates that the relationship of the equations is obtained irrespective of the actual length of the members 28 and 38 and the angle from the horizontal plane. Therefore, in order to obtain the relationship of the expression, the first auxiliary frame 2
The zero and second auxiliary frames 22 are rigidly connected to the columns 10 and 12, respectively, and can be displaced as the columns are deformed, as long as they can transmit the horizontal load of the earthquake to the damper member. It turns out that the form may be used.
