BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame for a building, and more particularly, to a frame for a building used in a steel structure such as a factory or a warehouse.

Typical buildings such as houses and buildings are constructed using materials such as reinforced concrete or steel-concrete. In the case of a building such as a factory, a building, a warehouse or the like, a frame is formed of a steel frame, and a metallic panel is mounted on the roof and the wall on a frame formed of a steel frame. In the case of such a steel frame structure, not only the process such as concrete casting is greatly reduced but also most of the steel frame frames are manufactured after being manufactured in a factory, and thus the air is greatly reduced.

However, in the case of a building constructed only of steel frame, there is a high possibility that local buckling occurs at a portion where loads are concentrated. As a result, it is disadvantageous in comparison with an ordinary reinforced concrete (RC) concrete building due to an uncertain load caused by an earthquake, snow, wind and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a frame for a building which is easy to construct and has excellent seismic performance.

Particularly, it is intended to reinforce a joint surface between a column and a beam (a raft portion) so as to reduce a stress applied to the portion according to an earthquake load. It is also intended to reduce the stress applied to the columnar web in the vicinity of the joint surface.

It is also an object of the present invention to maintain and maintain the internal space utilization of the building despite the arrangement of the reinforcing plate for reducing the stress.

In order to solve the above-mentioned problems, an embodiment of the present invention is a building frame comprising a raft portion for supporting a roof, and a column portion fixed to the raft portion at one end and fixed to the ground at the other end, A raft inner flange facing one side of the interior of the building; a raft outer flange disposed facing away from the raft inner flange and having one surface oriented toward the roof of the building; And an end plate disposed at one end of the raft web and forming a joining surface with the column portion, wherein the column portion is formed to be larger at the other end coupled with the raft portion than the one end at which the height of the column web is fixed to the ground And an engagement surface coupled to an inner surface of at least one of the inner and outer flanges of the raft, Steel plate; And a column web reinforcement plate arranged and connected to a side surface of the column web adjacent to the joining surface.

Wherein the bonding surface reinforcing plate comprises: a first plate extending at a predetermined constant width from one end; And a second plate which is extended from the first plate and whose one side is inclined uniformly toward the other side to gradually decrease the width.

It is preferable that the joint surface reinforcing plate is disposed so that the end portion of the first plate is positioned near the end plate and the inclination direction of the second plate is directed toward the outside of the raft web.

The first plate may be formed thicker than the second plate.

The bonding surface reinforcing plate may further include a third triangle-shaped plate vertically coupled to the side surfaces of the first and second plates that extend in a straight line.

Wherein the column web reinforcing plate is C-shaped having the same inner and outer curvatures, the convex portion of the C-shaped convex portion is fixed to the ratchet portion and the column portion is directed to the outside, and the overall shape is inclined to the right- Can be combined.

Wherein the column web reinforcing plate has a symmetrical C-shape with a narrow width of the convex portion having different inner and outer curvatures, the convex portion facing outwardly of the ratchet portion and the column portion fixedly joined, And can be arranged in an oblique upper-right room.

The column web reinforcing plate is semicircular in shape, and the semicircular convex portion is directed toward the outside of the ratchet portion and the column portion fixedly joined to each other, and the overall shape can be inclined and arranged in an upper right direction.

The column web reinforcement plate may have a straight bar shape, and the straight bar shape may be integrally disposed to be inclined toward the upper right chamber from the joining face.

The column web reinforcement plate may have a necklace shape in which a circular shape of the same diameter is partially overlapped and connected in a straight line, and the necklace shape may be disposed to be inclined toward the upper right side of the joint surface as a whole.

Wherein the column web reinforcement plate has a shape of a dog bone extending in the same width at both ends and having a gradually decreasing width in the vicinity of the center, and a shape of the dog bone is inclined with respect to the joining face as a whole And can be arranged and bound toward the upper right room.

And a column stiffener disposed on the extension of the inner and outer flanges of the rack, wherein the center of gravity of the column web reinforcement plate is disposed in the center of a panel zone formed by the column stiffener .

As described above, according to the present invention, various effects including the following can be expected. However, the present invention does not necessarily achieve the following effects.

It is possible to provide a frame for a building which is easy to construct and has excellent seismic performance. Particularly, a joint surface reinforcing plate having a tapered shape is joined and reinforced to the flange near the joining face of the column and the beam (the raft portion), so that the stress applied to the joining face can be reduced by 10% or more in accordance with the seismic load. As a result, the response correction coefficient can be improved.

Further, since the joint surface reinforcing plate is arranged in the thickness direction of the flange of the raft portion, the internal space utilization of the building can be further increased.

In addition, the column web reinforcing plate is joined and reinforced, and the stress applied to the column web near the bonding surface can be reduced by about 8%.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

1 is an exploded perspective view of a building using a building frame according to a first embodiment of the present invention.

As shown in FIG. 1, the building using the building frame of the first embodiment of the present invention includes a first building frame 100 arranged at a plurality of intervals in the longitudinal direction of the building, a first building frame 100 and a panel 300 fixed on the upper surface of the secondary frame 200. The secondary frame 200 supports the primary building frame 100 between the primary frame 200 and the secondary frame 200,

As shown in FIG. 1, a building using the building frame according to the first embodiment of the present invention is a building used for a factory, a distribution center, a hangar, etc., and is constructed of a steel frame and a panel 300. The building frame according to the first embodiment of the present invention corresponds to the first building frame 100 shown in Fig. 1, and is hereinafter abbreviated as a building frame.

Fig. 2 is a front view of the frame for building of Fig. 1, Fig. 3 is a perspective view of the structure of Fig. 2, and Fig. 4 is a perspective view of the bonding surface reinforcing plate 200a of Fig. 2 according to the first embodiment.

2 and 3, a building frame according to an embodiment of the present invention includes a roof 110 for supporting a roof, a pillar fixed to the cage 110 at one end and fixed to the ground at the other end, A joining face reinforcement plate 200a coupled to the inner and outer flanges 111 and 112 of the cage portion 110 and a column web reinforcement plate 200a coupled to the column webs 123 of the column portion 120, (300).

The raft portion 110 includes a raft inner flange 111 having one side facing the interior of the building and a raft outer flange 112 spaced apart from the inside of the raft inner flange 111 and disposed one side toward the roof of the building, A raft web 113 connecting the raft inner flange 111 and the raft outer flange 112 and an end plate 114 disposed at either end to form the pillar portion 120 and the joining surface 115 do.

The raft inner flange 111 and the raft outer flange 112 are coupled to each other on the upper and lower sides of the raft web 113 to have a generally H-shaped cross-sectional shape. In addition, the height of the raft web 113 is variably formed in accordance with the stress (typically, a moment diagram) applied to the raft portion 110 formed by the load applied to the structure.

The end plate 114 is disposed at one end of the cradle 110 perpendicularly to the cradle web 113 to form the cradle 120 and the cradle 115 to reinforce the rigidity of the cradle 115 do. Specifically, the width of the end plate 114 is the same as the height of the cage 113, and one end of the cage 110 is clogged by the arrangement of the end plate 114.

That is, in the cradle 110, the cradle 111 and the cradle 112 are a kind of horizontal plate, and the cradle 113 and the end plate 114 can be regarded as a kind of vertical plate.

The column portion 120 includes a column inner flange 121 whose one side faces the building interior and a column outer flange 122 which is disposed apart from the column inner flange 121 and faces the outside of the building, And a column web 123 connecting the column inner flange 121 and the column outer flange 122. [

The columnar flange 121 and the columnar flange 122 are also coupled to the columnar web 123 in the upper and lower directions to form an H-shaped cross section as a whole. The height of the column web 123 is larger at the other end coupled with the crawler 110 than at one end fixed to the ground. That is, in FIG. 2, H2 is formed larger than H1. This is also because it is variably formed in accordance with the stress applied to the column formed by the load applied to the structure.

On the other hand, the column stiffener 124 can be further disposed and coupled to the other end. At this time, the pillar stiffener 124 is arranged to lie on each extension line of the rack inner flange 111 and the outer rack flange 112 of the coupled crawler portion 110. As a result, a panel zone having a predetermined area is formed at the other end of the post 120.

In the structure of the embodiment of the present invention, the foundation (the portion where the column portion 120 and the surface are fixed) is pinned (i.e., the horizontal load and the vertical load are fixed to the foundation but the moment load The coupling between the pillar 120 and the cradle 110 is rigid (i.e., not only in the horizontal and vertical directions but also between the pillar 120 and the cradle 110) And also supports a moment load applied therebetween). As a result, when a load reciprocating in the horizontal direction, such as an earthquake, is applied, the greatest load is applied to the joint surface 115, and local buckling or the like also occurs at the joint surface 115.

In order to reinforce the local buckling which may occur due to an earthquake or the like, the joint surface reinforcement plate 200a and the column web reinforcement plate 300 are further joined to the joint surface 115. [ At this time, a welding method capable of maintaining the original shape of the plate inherently by the joining method can be used.

In this way, when an unexpected support load or the like is applied to the structure, the bonding face reinforcing plate 200a and the column web reinforcing plate 300 not only increase the rigidity of the structure but also cause plastic deformation and the like , It not only prevents the frame 100 of the primary structure from being deformed in a primary way but also slows down the time required for the frame 100 to be destroyed.

In detail, the seismic design coefficient Cs of the building is determined by the following equation (1).

Figure 112015118205614-pat00001

S is the acceleration coefficient determined by the area and the ground, I is the importance coefficient determined by the use of the building, R is the reaction correction coefficient, T is the natural period of the building

Here, the reaction correction coefficient is determined by the following equation (2).

Figure 112015118205614-pat00002

Rμ: ductility coefficient, R Ω : excess strength coefficient, R ζ : damping coefficient

As the seismic design coefficient decreases, the seismic performance of the building improves. Accordingly, as the response correction coefficient increases, the seismic performance improves. By adding the bonding surface reinforcing plate 200a and the column web reinforcing plate 300 to the above reaction correction coefficient, the excess strength coefficient naturally increases. In addition, even if the ultra-low load due to the earthquake is applied to the building frame, The plate 200a and the column web-reinforcing plate 300 are first plastically deformed to increase the ductility coefficient and the damping coefficient, thereby increasing the reaction correction coefficient as a whole.

These advantages were confirmed by finite element analysis.

3, the joint surface augmentation plate 200a is particularly coupled to the inner surface of at least one of the inner and outer flanges 111, That is, since the longitudinal section of the raft section 110 is H-shaped, the inner surface of the raft section 110 can be divided on the basis of the raft web 113, and the joint surface reinforcement plate 200a is disposed on the inside The rigidity of the joint surface 115 can be reinforced and the seismic performance can be improved.

Referring to FIG. 4, the bonding surface reinforcing plate 200a is composed of first and second plates 210a and 220, and has a generally tapered shape. First, the first plate 210a has a rectangular panel shape which is constantly extended at a predetermined width from one end. In addition, the second plate 220 extends from the first plate 210a, and the one line extending from the first plate 210a is inclined uniformly toward the other line, and the width thereof is gradually reduced. The first and second plates 210a and 220 may be integrally formed with the joint surface reinforcing plate 200b.

The joint surface reinforcing plate 200a is disposed such that the end of the first plate 210a is positioned near the end plate 114 and the direction of inclination of the second plate 220 is directed toward the outside of the crawler web 113. [ In addition, it is preferable that the joint face reinforcement plates 200a are further arranged in the same manner on the opposite side of the raft web 113 so as to be symmetrical with the already-bonded joint reinforcement plates 200a, and are arranged in a pair.

As a result, a total of four bonded surface strengthening plates 200a are joined to the two inner rafter flanges 111 and two outer flange rafters 112, respectively. Accordingly, the energy transmitted due to an earthquake or the like can be effectively absorbed and the rigidity of the joint surface 115 can be further reinforced.

5 is a perspective view of the bonding face reinforcing plate 200b according to the second embodiment. Referring to FIG. 5, the first plates 210a and 210b are formed to be thicker than the second plate 220. As a result, the joint surface strengthening plate 200b has an increased ability to dissipate energy as a whole by the first plate 210, which is reinforced by the step difference. Particularly, as shown in the stress distribution diagram in comparison with the first embodiment, the maximum stress applied to the columnar web 123 in the vicinity of the joint surface 115 is reduced from 418 MPa to 383 MPa, and the stress applied to the end of the joint surface reinforcement plate 200b It can be seen that the maximum stress or 417Mpa decreased from 420Mpa.

However, the ratio of the thickness between the first plate 210b and the second plate 220 and the portion formed thicker in the first plate 210 may vary depending on design changes and the like.

Fig. 6 is a perspective view of a bonding face reinforcing plate 200c according to the third embodiment. Referring to FIG. 6, the third plate 230 is vertically coupled to the side surfaces of the first and second plates 210a and 220 that extend in a straight line. At this time, the shape of the third plate 230 has a right triangle shape as a whole. The opposite sides of the hypotenuse, which forms a right triangle, are coupled to the first and second plates 210a and 220. However, the shape of the third plate 230 may be formed as a curved line with the hypotenuse having a certain curvature.

7 is a stress distribution diagram in the vicinity of the joint surface 115 when a tensile force and a compressive force are applied to a frame for a conventional structure. FIG. 8 is a diagram showing the stress distribution diagram of FIG. 7 when the joint surface reinforcement plate 200a is applied, (115). ≪ / RTI > Here, the tensile force is a force applied so as to increase the rotation angle of the bonding surface 115 by 2%, and the compressive force is a force applied so that the rotation angle of the bonding surface 115 is further reduced by 2%.

7, when the tensile force is applied, the maximum tensile stress in the vicinity of the outer side of the bonding surface 115 is 357 MPa, and the maximum tensile stress in the vicinity of the bonding surface 115 in the vicinity of the bonding surface 115 is 326 MPa to be. When the compressive force is applied, the maximum tensile stress in the vicinity of the outer side of the bonding surface 115 is 346 MPa, and the maximum tensile stress in the column web 123 in the vicinity of the bonding surface 115 is 330 MPa.

8, the maximum tensile stress in the vicinity of the outer side of the joint surface 115 in tension is 319 MPa and the maximum tensile stress in the column web 123 in the vicinity of the joint surface 115 is 329 MPa. When the compressive force is applied, the maximum tensile stress in the vicinity of the outer side of the bonding surface 115 is 321 MPa, and the maximum tensile stress in the column web 123 in the vicinity of the bonding surface 115 is 332 MPa.

That is, due to the addition of the bonding surface reinforcing plate 200a, the stress in the vicinity of the bonding surface 115 is reduced by about 10%, but the stress acting on the column web 123 in the vicinity is slightly increased . Accordingly, the building frame according to one embodiment further includes a column web reinforcement plate 300 that can reduce the increased stresses in the column webs 123. [

The column web stiffening plate 300 is arranged in a panel zone formed by the side of the column web 123 adjacent to the end plate 114, in particular by the column stiffener 124 described above, have.

Figs. 9 to 14 are perspective views showing a deformable shape of the column web reinforcing plate 300. Fig.

First, in FIG. 9, the column web reinforcing plate 300 according to the first embodiment is a C-shaped steel plate having the same inner and outer curvatures. At this time, the width and thickness of the C-type steel plate are constant, and both ends thereof are semicircular. Particularly, the reason why the C-type steel plate is used is that it can easily absorb it in the form of elastic energy corresponding to the tensile force or compressive force externally applied due to its own shape. As a result, the C-type steel sheet can reinforce the rigidity around the columnar web 123 to which the C-type steel plates are arranged.

However, the coupling position is such that the convex portion of the C-shape is directed toward the outside of the cage portion 110 and the pillar portion 120 in which the intermediate convex portions are fixedly joined to each other, Thereby maximally increasing the energy that can be absorbed.

As a second embodiment, the column web reinforcing plate 300 of FIG. 10 is a symmetrical C-shaped steel plate having different inner and outer curvatures, and the width of the intermediate convex portion is particularly narrow. However, the width can be adjusted through design changes such as inner or outer curvature adjustment.

On the other hand, as described above with reference to Fig. 9, the joining position is such that the convex portion is directed toward the outside of the cage portion 110 and the pillar portion 120 to which the convex portion is fixedly joined, and the overall shape is inclined to the joining face 115 in the right- desirable.

As a third embodiment, the column web reinforcement plate 300 of Fig. 11 is a semicircular steel plate. 9 and 10, the stress distribution around the column web 123 to which the semicircular steel plate is coupled with respect to the tensile force and compressive force applied can be reduced.

9 and 10, it is preferable that the coupling position is directed to the outside of the cage portion 110 and the pillar portion 120 in which the convex portion is fixedly connected, and the overall shape is disposed in an upper right room with an inclination with respect to the joint surface 115 .

As a fourth embodiment, the column web reinforcement plate 300 of Fig. 12 is a straight rod-shaped steel plate. On the other hand, it is preferable that the engaging position is disposed toward the upper right chamber as a whole from the joining face 115 in an inclined manner. At this time, the width may be about 10% of the vertical width.

As a fifth embodiment, the column web reinforcement plate 300 of FIG. 13 is a necklace-shaped steel plate in which circular portions of the same diameter are partially overlapped and connected in a straight line. On the other hand, it is preferable that the joining position is disposed such that the necklace shape is inclined from the joining surface 115 as a whole toward the upper right room.

As a sixth embodiment, the column web reinforcement plate 300 of Fig. 14 is a dog bone-shaped steel plate. Specifically, the shape is extended so as to be close to the same width at both ends, while the width is gradually decreased at the vicinity of the middle. On the other hand, it is preferable that the dog-bone shape is disposed toward the upper right room with the joining face 115 as a whole inclined with respect to the joining position.

On the other hand, the center of gravity of the column web stiffening plate 300 according to the first and sixth embodiments is disposed in the center or near the center of the panel zone. That is, the column web reinforcement plate 300 is disposed in a diagonal direction connecting two corners of the panel zone.

FIG. 15 is a stress distribution diagram when a tensile force and a compressive force are applied to a frame for a building applied to the center of the panel zone in the column web reinforcement plate 300 in FIG. 7, and FIG. 16 is a stress distribution diagram when the column web reinforcement plate 300 And a stress distribution diagram when a tensile force and a compressive force are applied to a building frame applied to the outer edge of the panel zone. Here, the tensile force is a force applied so as to increase the rotation angle of the bonding surface 115 by 2%, and the compressive force is a force applied so that the rotation angle of the bonding surface 115 is further reduced by 2%.

As can be seen from these figures, the maximum tensile stress and the maximum compressive stress in FIG. 15 are 302 MPa and 4 MPa, respectively, while the maximum tensile stress and the maximum compressive stress are 32 MPa and 28 MPa, respectively, It can be seen that it is more advantageous to arrange it in the vicinity of the center of FIG. That is, when the column web reinforcement plate 300 having a larger size is arranged near the center of the panel zone, the energy due to the tensile force and compressive force applied can be absorbed to the maximum.

Through such analysis, the stress applied to the panel zone can be reduced by about 8% compared with the arrangement in the vicinity of the outer edge when the column web reinforcement plate 300 is disposed in the vicinity of the center.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
