Description

TECHNICAL FIELD [0001] The present invention relates to a seismic energy dissipating device using a displacement control plate and a friction plate, and a seismic energy dissipating method using the same. [0002]

The present invention relates to a seismic energy dissipating device using a displacement control plate and a friction plate, and a method of seismic strengthening using the same. More particularly, to a seismic energy dissipating device using a displacement control plate and a friction plate that can more effectively and economically control the seismic reinforcement of a structure through damping by friction and plastic deformation, and a method of seismic reinforcement using the same.

For conventional wind loads and small-scale earthquakes, the energy dissipation capacity due to the viscoelastic deformation of the high-damping rubber reduces the vibration energy of the main structure and minimizes the residual deformation. For the maximum level of earthquake including the design earthquake, A conventional composite vibration damping device capable of minimizing the damage of the main structure by controlling the vibration of the structure due to the elasto-plastic deformation of the vibration damper is introduced.

That is, it can be said that the steel pin 30 absorbing the vibration in the earthquake of the design level or higher and the high-damping rubber 20 suppressing the vibration in the wind or the small-scale earthquake are combined to form one vibration damper.

Specifically, as shown in FIG. 1A, the conventional composite vibration damping device B includes a plurality of pin stop holes 112a at least one of which is parallel to one another at regular intervals, and a plurality of pin stops A plurality of side plates 102a, 104a, 102b, 104b corresponding to a straight line with the ball and having a pin engagement hole 112b formed in a relatively small diameter and an end plate 120b connected vertically to one end of the plurality of side plates, A pair of damper bodies 10a and 10b provided so as to overlap the plurality of side plates in a state where both end plates face each other; A plurality of highly damped rubbers (20) installed between the plurality of side plates and viscoelasticly deformed; And a steel pin (30) having a plastic hinge portion (30a) inserted into a plurality of pin stop holes and a pin coupling hole on the side of a pair of damper bodies, respectively, and having a diameter smaller than that of the other portions.

At this time, one end of the steel pin 30 is loosely inserted into the pin stop hole 112a of the one side plate 102a and the other end is fastened to the pin coupling hole 112b of the other side plate 102b. Therefore, the steel pin 30 is spaced apart from the pin stop hole 112a, and the high-damping rubber 20 is viscoelastically deformed to absorb the vibration energy within the clearance. The steel pin 30 may be fixed to the side plate 102a by a nut 32 after a screw is formed at one end thereof and is screwed to the pin fixing hole 112b.

Accordingly, when an earthquake smaller in magnitude than the wind load or the design earthquake acts, the high-damping rubber 20 interposed between the side plates 102a, 104b, 104a, 102b of the damper bodies 10a, Absorbing,

When a maximum level of earthquake greater than the design earthquake is applied, the plastic hinge portion 30a of the steel fins 30 is plastically deformed to dissipate the earthquake energy.

As shown in FIG. 1B, when a wind or an earthquake is applied to the structure, a shear force (arrow) is generated in the hollow beam A, and a composite vibration damper B installed in the center of the hollow beam Or by shear forces generated by earthquakes.

Accordingly, when micro-deformation due to a wind or a small-scale earthquake occurs, the high-damping rubber 20 is slightly deformed in response to the shear behavior to reduce the vibration. At this time, one end of the steel pin 30 is fixed to the pin fixing hole 112b, but the other end has a predetermined clearance with the pin stopping hole 112a, so that the steel pin 30 can move freely, and thus the deformation does not occur.

Further, when a large deformation due to an earthquake equal to or higher than the design level occurs, the steel pin 30 comes into contact with the pin stop hole 112a, thereby causing the steel pin 30 to plastic deform and dissipate the earthquake energy.

However, since the complex vibration damper installed in such a conventional hollow beam (B) does not have a large frequency of occurrence of large deformation due to an earthquake equal to or higher than the design level, it is possible to provide a composite vibration damper A device is also required, but a composite vibration damping device related thereto is not introduced.

Accordingly, the present invention is installed between structures deformed and acted by earthquake energy and overlaps with each other, so that plastic displacement of carbon plate is generated arbitrarily with friction damping at a desired design level, so that seismic energy can be dissipated to enable more efficient design and application A seismic energy dissipating device using a displacement control plate and a friction plate, and a method of providing a seismic reinforcement method using the same.

According to an aspect of the present invention,

First, an earthquake energy dissipating device using the displacement control panel and the friction plate of the present invention is installed between deformable structures such as a girth beam.

The seismic energy dissipation device using such a displacement control plate effectively suppresses seismic energy due to arbitrary design classification and earthquake energy due to excitation by the frictional damping by the friction plate and the plastic deformation damping by the displacement plate and the carbon plate between the deformable behavior structures It is dispersed.

Second, in the earthquake energy dissipating device using the displacement control plate and the friction plate, both of the horizontal flat plate flanges of the housing of the U-shaped cross section are connected to each other by the connecting holes provided to penetrate the slit connection holes formed in the horizontal plate flanges, And the friction plate is horizontally formed between the horizontal plate flanges overlapped with each other to enable damping by friction and the displacement control plate extends horizontally to the side plate of the housing having the U-shaped cross section. Therefore, the carbon steel plate is placed in a vertical plate between the upper and lower horizontal plate flanges so that the plastic deformation by the displacement control plate is generated.

Accordingly, the displacement control plate can contact the deformation inducing groove at a desired design level, plastic deformation of the carbon steel plate, and the seismic energy can be dissipated at an arbitrary point in time.

In other words, it is possible to dissipate the earthquake energy by friction damping by the friction plate at a certain design level or below, to dissipate the seismic energy by plastic deformation of the carbon plate by the displacement control plate at a predetermined design level or higher, The friction damping by the friction plate can be performed again until the connecting hole fastened to the slit connecting hole contacts the slit connecting hole.

To this end,

A housing member having a pair of U-shaped cross-sections, the horizontal plate flanges extending horizontally overlapping each other and bound by a connecting hole formed on an inner side of a lower end and an upper end of the side plate; A friction plate provided between the horizontal plate flanges horizontally overlapped with each other; A carbon steel plate fixed between upper and lower horizontal plate flanges overlapped with each other so as to be positioned at a central portion of the housing member having the pair of U-shaped cross sections; And a displacement control plate extending horizontally from the inside of the side plate to contact both side surfaces of the carbon steel plate, and a seismic energy dissipating device using the friction plate and a method of seismic strengthening using the friction plate.

The seismic energy dissipating device using the displacement control plate and the friction plate according to the present invention can freely adjust the number of the carbon steel plates capable of dissipating the earthquake energy and arbitrarily control the deformation point by using the displacement control plate. Since the damping capacity can be adjusted, it is possible to construct a damper which is very efficient and economical, and it can be easily applied to a deformation behavior structure or the like because it extends horizontally as a whole.

Also, the seismic energy dissipation device using the displacement control plate and the friction plate is composed of the displacement control plate, the seismic energy dissipation device using the friction plate and the seismic energy dissipation device which can control the friction plate more dynamically before and after damping by the plastic deformation of the carbon plate by the displacement control plate It is possible to provide a seismic strengthening method using the structure.

[Operation of Seismic Energy Dissipation Device (100) Using Displacement Control Plate and Friction Plate)

2 is a functional diagram of an earthquake energy dissipation apparatus 100 using a displacement control plate and a friction plate according to the present invention.

The seismic energy dissipating device 100 using the displacement control plate includes a pair of U-shaped cross-section housing members 100a, 100b including the horizontal plate flanges 120a, 120b and the displacement control plates 150a, And the friction plates 110a and 110b are set between the overlapping horizontal plate flanges 120a and 120b so that the horizontal plate flanges 120a and 120b of the horizontal plate flanges 120a and 120b overlap each other by a predetermined length, And the carbonaceous sheet 140 fixed between the upper and lower sides of the horizontal plate flanges 120a and 120b overlapped with each other so as to be located at the center of the pair of housing members 100a and 100b having a pair of U- As shown in FIG.

Displacement control grooves 141 are formed on both sides of the carbonaceous plate 140. Displacement control plates 150a and 150b in the form of a horizontal plate are fixed to the center of the inner surfaces of the both side plates so as to contact the deformation inducing grooves Is formed.

The seismic energy dissipating device 100 using the respective displacement control panels is constructed such that the housing members 100a and 100b having respective U-shaped cross sections are connected to the deformable behavior structure 200 such as a hollow beam by a connecting hole 160, As shown in FIG.

When horizontal force is generated by the earthquake in the deformable behavior structure 200,

First, friction damping by the friction plates 110a and 110b is generated. That is, frictional damping due to seismic energy dissipation occurs due to the frictional force between the horizontal plate flanges 120a and 120b attached between the horizontal plate flanges 120a and 120b and the friction plates 110a and 110b contacting the upper and lower surfaces.

These friction plates 110a and 110b absorb the earthquake energy while viscoelastic resistance and deformation between the horizontal plate flanges 120a and 120b. The friction plates 110a and 110b are made of a damping rubber plate. The damping rubber plate is generally formed by adding additives such as fillers, vulcanizing agents, antioxidants and plasticizers to natural rubber and / or carbon black, The elasticity can be adjusted according to the ratio of the additive and the energy dissipation capacity can be adjusted by elasticity.

When the horizontal force due to an earthquake or the like is equal to or higher than the design level, the displacement control plate 150 is brought into contact with the deformation inducing groove 141 of the carbon steel plate 140 before the horizontal plate flange contacts the side plate. Is broken on the basis of the strain inducing groove (141).

Accordingly, the present invention can quantitatively determine the seismic energy dissipation capacity by adjusting the number of installed carbonaceous plates 140,

The damping by the plastic deformation by the seismic energy dissipating device using the displacement control plate can be made at the time of occurrence of any earthquake energy by the displacement control plate 150.

After the carbonaceous plate 140 is broken, the coupling holes 170 fastened to the slit connection holes 122 (bolt holes) by nuts or the like are inserted again into the friction plates 110a and 110b until they are brought into contact with the slit connection holes 122, So that friction damping can be achieved.

The slit connection hole 122 extends in the horizontal direction and is formed to be larger than the diameter of the coupling hole 170. The carbon plate 140 is also shaped like a vertical plate so that both side surfaces thereof are parallel to the displacement control plates 150a and 150b As shown in Fig.

[Seismic Energy Dissipation Device Using Displacement Control Plate and Friction Plate (100)]

3A and 3B are a perspective view and an installation perspective view of a seismic energy dissipating device 100 using a displacement control plate and a friction plate according to the present invention.

The seismic energy dissipating device 100 using the displacement control plate includes friction plates 110a and 100b, horizontal plate flanges 120a and 120b, side plates 130a and 130b, a carbon plate 140, displacement control plates 150a and 150b And a housing member 100a, 100b having a pair of U-shaped cross-sections including connecting portions 160a, 160b and a connecting portion 170. [

In other words, it can be seen that the housing members 100a and 100b of the respective U-shaped cross sections are arranged so as to be opposed horizontally to each other in the same shape.

Thereby, the housing members 100a and 100b having a plurality of U-shaped cross-sections can be manufactured, and the two housing members 100a and 100b can be used in combination. Here, the housing member 100a having a U-shaped cross section will be referred to as a reference.

It is to be understood that the side plate 130a is formed in the form of a vertical plate and a plurality of horizontal connection ports 160 such as a reinforcing bar and a section steel are formed on the rear surface to form a connection structure The housing member 100a having a U-shaped cross section is moved integrally with the deformation and behavior structure 200 while the rear surface of the housing member 100 is buried and the rear surface contacts the deformation and behavior structure 200. [

The horizontal plate flange 120a includes a horizontal plate flange 120b and a horizontal plate flange 120b of a housing member 100b having a U-shaped cross section, each plate member extending horizontally and opposed to the upper and lower ends of the side plate 130a, Are set so as to overlap each other.

The connector 170 is formed to vertically penetrate a plurality of slit connection holes 122 formed in the horizontal plate flanges 120a and 120b so that the housing members 100a and 100b having a U- And serves as a fastener for maintaining the overlapped state.

At this time, a friction plate 110a is installed between the overlapping horizontal plate flanges 120a and 120b of the housing members 100a and 100b having the U-shaped cross section, thereby enabling friction damping.

The carbonaceous sheet 140 has a vertical plate shape in which upper and lower surfaces are fitted and fixed to slit grooves 121 formed in the horizontal plate flanges 120a and 120b of the housing members 100a and 100b having a U- The grooves 121 are formed so that both side surfaces are arranged in the horizontal direction.

It is preferable that such a slit groove 121 is formed only in the housing member 100a having a U-shaped cross section so that the insertion of the carbon steel plate can be facilitated, but a slit groove may be formed in the housing member 100b having a U- .

Although the carbonaceous sheet 140 is shown as being formed in the I-shape, it is not limited thereto, and it can be seen that the deformation inducing grooves 141 are formed on both sides of the steel sheet using the steel sheet.

The deformation inducing groove 141 allows the roughly intermediate portion of the carbon-based plate 140 to be more easily broken.

The seismic energy dissipating capacity of the seismic energy dissipating device 100 using the displacement control plates 150a and 150b is adjusted because the seismic energy dissipating capacity can be determined quantitatively by the number of the installed carbon plate 140 .

The position of the carbonaceous plate 140 is formed such that the end face of the displacement control plate 150, which will be described later, is not in contact with the housing members 100a and 100b having the U-shaped cross section initially overlapped by the horizontal plate flange.

Next, the displacement control plate 150a is a plate member horizontally extending on the inner side of the center of the side plate 130a. In the state where the housing members 100a and 100b having a U- And the housing members 100a and 100b having a U-shaped cross section are overlapped with each other as shown in FIG. 3B to act as a wedge in the deformation inducing groove 141 of the carbon plate 140, As shown in FIG.

The displacement control plate 150a is formed to have the same width as the width of the side plate 130a so that the displacement control plate 150a can contact the plurality of deformation inducing grooves 141 at the same time.

Thus, the present invention allows the displacement control plate 150 to be deformed at a desired design level by contacting the deformation inducing groove at the desired design level only by adjusting the length of the displacement control plate 150 in the horizontal direction, thereby plasticizing the carbon steel plate and dissipating the seismic energy at an arbitrary point in time.

That is, at a certain design level or lower, the seismic energy dissipating devices using the displacement control plate overlap each other and dissipate the seismic energy by the friction plate 110a. At a certain design level or higher, the carbon plate is plastic deformed by the displacement control plate, And friction damping by the friction plate 120a is enabled until the connecting hole, which is coupled to the slit connection hole, comes into contact with the slit connection hole again by the earthquake energy caused by the excitation or the like.

3A, the housing member 100b having a U-shaped cross section has the same structure as the housing member 100a having a U-shaped cross section and friction plates 110a and 110b are provided between the horizontal plate flanges of the housing members 100a and 100b having a U- And is restrained by the connector 170.

As shown in FIG. 3B, the housing members 100a and 100b having a U-shaped cross section are horizontally overlapped with each other due to the horizontal force due to the earthquake energy, so that friction damping by the friction plates 110a and 110b as well as displacement control plates 150a and 150b When the earthquake occurs at a predetermined design level or more as shown in FIG. 2, the carbon steel plate 140 can be broken, and the connection hole 170 fastened to the slit connection hole 122 by a nut, Friction damping by the friction plate can be performed again until the friction plate is brought into contact with the slit connection hole.

[Structural Seismic Retrofit Method Using Seismic Energy Dissipation Device (100) Using Displacement Control Plate and Friction Plate)

4 is a view showing a construction of a seismic energy dissipation method using a seismic energy dissipation device 100 using a displacement control plate and a friction plate according to the present invention.

It can be seen that the structure is formed as a deformable behavior structure 200 such as a ribbed beam spaced apart from each other.

Next, the housing member 100a, 100b having a U-shaped cross section is integrally installed between the deformed and deformable structures 200 by means of a connecting hole 160 including a section steel or the like, so that the earthquake using the displacement control plate and the friction plate of the present invention The energy dissipating device 100 is simply set to the initial setting.

This initial setting is a state in which the horizontal plate flanges of the housing members 100a and 100b having a pair of U-shaped cross sections including the horizontal plate flanges 120a and 120b and the side plates 130a and 130b are set to overlap with each other, A plurality of carbon plates 140 are formed in the form of a vertical plate between the vertically spaced horizontal plate flanges 120a and 120b and between the vertical plate flanges 120a and 120b, The control plates 150a and 150b are not in contact with the carbon black plate 140.

Friction forces are generated between the friction plates 110a and 100b between the overlapping horizontal plate flanges 120a and 120b and furthermore the displacement control plates 150a and 150b are pressed against the carbon steel plates 150a and 150b, Damping is induced by plastic deformation while inducing the fracture while contacting with the upper plate 140. After the carbon upper plate 140 is broken, friction damping by the friction plates 110a and 100b occurs again.

As a result, it is possible to provide a seismic energy dissipating apparatus 100 using the displacement control panel according to the present invention with a simple structure. Even if the structure of the inward beam, which is the deformation behavior structure 200, And serves as a vibration suppression device capable of dissipating the earthquake energy.
