As described above, the frame type structure 100 includes the first pillar 10 and the second pillar 20 that are connected. The frame type structure 100 can suppress the protrusion of the pillars (the first pillar 10 and the second pillar 20) from the wall surface, compared to the case where one large pillar is used. Therefore, according to the frame structure 100,
It is possible to use the indoor space more freely.

In the frame structure 100, the connecting members 50 and the intermediate connecting members 60 improve the bending rigidity of the first column 10 and the second column 20 around the Y axis (around the strong axis). Furthermore, the frame structure 100
, the rib 15 and the rib 25 overlap the beam 40 and the connecting member 50 in the YZ plane view. This suppresses deformation of the flanges 11, 12, 21, and 22 when a load in the X direction is applied from the beam 40 to the first column 10 and the second column 20. For this reason,
The bending rigidity of the first column 10 and the second column 20 around the Y axis (around the strong axis) is improved. Further, the web 13 of the first pillar 10, the web 23 of the second pillar 20, the web 53 of the connecting member 50, and the web 43 of the beam 40 overlap in the YZ plane view. This further improves the bending rigidity of the first column 10 and the second column 20 around the Y axis (around the strong axis). Furthermore, in the frame structure 100, the first pillar 10
And the second pillar 20 is continuous without being divided in the Z direction. This improves the bending rigidity of the first column 10 and the second column 20.

By having the above-described structure, the frame type structure 100 can suppress deformation of the first column 10 and the second column 20 when a horizontal force is applied to the building due to an earthquake. The frame structure 100 can reduce interstory displacement (relative horizontal displacement of the upper floor with respect to the lower floor). Frame structure 1
00 can improve earthquake resistance.

Note that the flange 51 is an example of a first plate joined to the first beam flange 71 of the cross beam 70. The first plate is not limited to the flange 51. For example, the first beam flange 7
1 may be joined to the rib 15. That is, the first plate may be the rib 15. The first plate is arranged between the flange 12 of the first column 10 and the flange 21 of the second column 20, between the pair of flanges (flange 11 and flange 12) of the first column 10, and between the pair of flanges (flange 11 and flange 12) of the second column 20. It may be provided at least at any position between the flanges (flange 21 and flange 22).

The first beam flange 71 does not necessarily need to be joined to the first plate by groove welding. The first beam flange 71 may be joined to the first plate by fillet welding, for example.
Further, the first beam flange 71 may be joined to the first plate by a fixing member such as a bolt. However, it is desirable that the first beam flange 71 be joined to the first plate by groove welding, since the bending moment is easily transmitted.

The flange 52 is an example of a second plate joined to the second beam flange 72 of the cross beam 70. The second plate is not limited to the flange 52. For example, the second beam flange 72 is
It may be joined to the rib 25. That is, the second plate may be the rib 25. The second plate is arranged between the flange 12 of the first column 10 and the flange 21 of the second column 20,
It may be provided at least at any position between the pair of flanges (flange 11 and flange 12) of the second column 20 and between the pair of flanges (flange 21 and flange 22) of the second column 20.

The second beam flange 72 does not necessarily have to be joined to the second plate by groove welding. The second beam flange 72 may be joined to the second plate by fillet welding, for example.
Moreover, the second beam flange 72 does not necessarily have to be joined to the second plate by welding. The second beam flange 72 may be joined to the second plate by a fixing member such as a bolt. However, in that the bending moment is easily transmitted, the second beam flange 72 is
Preferably, it is joined to the second plate by groove welding.

The thickness direction of the first plate and the second plate does not necessarily have to be parallel to the Z direction.
The first plate and the second plate may be inclined with respect to the horizontal plane. The longitudinal direction of the cross beam 70 is not necessarily parallel to the Y direction. For example, when the longitudinal direction of the cross beam 70 is inclined with respect to the horizontal plane, it is desirable that the thickness direction of the first plate and the second plate be perpendicular to the longitudinal direction of the cross beam 70.

As explained above, the frame type structure 100 of this embodiment includes the first column 10 and the second column 20.

It extends along the thickness direction of the web 13. The first plate and the second plate are connected to the first column 10.
between the flange 12 of the second column 20 and the flange 21 of the second column 20, between the pair of flanges (flange 11 and flange 12) of the first column 10, and between the pair of flanges (flange 21 and flange 22) of the second column 20. It is provided in at least one position between the two. A first beam flange 71, which is one flange of the cross beam 70, is joined to the first plate. The second beam flange 72, which is the other flange of the cross beam 70, is joined to the second plate.

A bending moment acts on the cross beam 70. The bending moment acting on the cross beam 70 is
It may be better to transmit the information to the first pillar 10 and the second pillar 20. On the other hand, frame structure 1
00, the first beam flange 71 is joined to the first plate (flange 51), and the second beam flange 72 is joined to the second plate (flange 52). As a result, the bending moment acting on the cross beam 70 is transferred to the first column 10 through the first plate and the second plate.
and is transmitted to the second pillar 20. The frame type structure 100 can transmit the bending moment of the cross beam 70 to the two connected columns. Furthermore, the frame type structure 100 can also transmit the axial force and shear force of the cross beam 70 to the two connected columns.

In the frame structure 100, the connecting member 50 is an H-shaped steel placed between the first column 10 and the second column 20. The first plate is one flange 51 of the connecting member 50. The second plate is the other flange of the connecting member 50.

As a result, the bending moment acting on the cross beam 70 is transferred to the first column 10 through the connecting member 50.
and is transmitted to the second pillar 20. Therefore, the bending moment acting on the cross beam 70 is
It becomes easier for the light to be evenly transmitted to each of the pillars 10 and the second pillars 20. The frame structure 100 can more evenly transmit the bending moment of the cross beam 70 to the two connected columns.
