In order to achieve the above object, a building structure of a building according to the present invention comprises a plurality of pillars arranged in a ring at predetermined intervals, and a beam is provided between adjacent pillars. Alternatively, an inner frame is formed by providing a reverse beam. A large number of columns are annularly arranged at predetermined intervals on the outside of the inner frame, and inverted beams are provided between adjacent columns to form an outer frame. A flat slab is erected between the inner and outer frames, and a stud provided with a vibration damping mechanism made of a member having a low yield point is provided at least in one of the inner and outer frames in the longitudinal direction.

According to the present invention, it is not necessary to provide pillars and beams on the floor, so that the floor can be freely laid out, and a high ceiling space can be realized. When a dwelling unit is formed, the arrangement of rooms and the like in the dwelling unit can be freely changed and updated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a building structure of a building according to the present invention will be described below with reference to the drawings.
The present invention is mainly applied to a high-rise house, and is constituted by combining a flat slab with a tube structure. Here, the tube structure means that when a force is applied from the side of the building, one of the outer columns is compressed and the other column is pulled, and in order to realize this, the outer The rigidity of columns and beams is greater than that of ordinary structures.

As shown in FIG. 1, the floor 1 of the building is
It has a planar square shape, and supports the slab with columns with capital without using a flat slab, that is, a beam. A common facility 2 composed of an elevator and stairs is arranged in the center of the floor 1, and a common corridor 3 is arranged on the outer periphery of the common facility. An inner frame 4 including pillars 4a, studs 4b, and beams 4c is arranged on the outer periphery of the corridor 3, and the inner frame forms a part of an inner wall. Although not shown, an entrance of each dwelling unit is provided on the inner wall.

The pillars 4a and the studs 4b are alternately arranged in a ring at predetermined intervals, thereby improving the rigidity and the horizontal strength of the building. The stud 4b is separated in the middle, and a steel damper, specifically, a vibration suppression mechanism (not shown) using a low-yield-point steel material is attached to the web of the H-section steel in the gap portion, and the stud 4b is integrated. It is designed to improve the earthquake resistance and livability of the building.
In addition, as a member having a low yield point, an extremely low yield point steel material may be used in addition to the low yield point steel material.

A beam 4 is provided between adjacent columns 4a and studs 4b.
c is provided, and the inner frame 4 is constituted by these pillars, studs, and beams. Note that the beam 4c is not limited to a general beam, and may be an inverted beam in which a floor slab is connected to a lower end of the beam. The outer periphery of the inner frame 4 is a dwelling unit area 5 where dwelling units are formed. An outer frame 6 composed of a pillar 6a, a stud 6b, and a reverse beam 6c is arranged on the outer periphery of the dwelling unit area 5, and the outer frame forms a part of an outer wall of the building. .

As shown in FIGS. 1 and 2, a pillar 6a and a stud 6b
Are alternately arranged in a ring at predetermined intervals. The stud 6b is separated in the middle like the stud 4b constituting the inner frame 4 described above, and a vibration damping mechanism 7 using a low yield point steel material for the web of the H-section steel in this gap. Are attached to form an integral unit. In addition, as a member having a low yield point, an extremely low yield point steel material may be used in addition to the low yield point steel material.

An inverted beam 6c is provided between the adjacent columns 6a and the studs 6b, and these columns, the studs, and the inverted beam form an outer frame 6. The reverse beam 6c also serves as a window stand, and a window glass is installed on the reverse beam. As described above, by forming the outer frame 6 with the inverted beams, the window portion is opened to the side of the ceiling, so that a wide daylighting area is secured, the daylighting property can be improved, and a high ceiling can be realized. Is possible.

At the lower part of the first floor, a seismic isolation device 8 composed of laminated rubber and steel dampers is provided to greatly reduce the horizontal force acting upon an earthquake, and to make columns 6a and beams 6c. Has greatly reduced the burden. For this reason,
In combination with the vibration damping mechanism 7 attached to the studs 4b, 6b, the seismic performance of the building is improved, and the livability is improved.

The studs 4b and 6b do not necessarily need to be arranged on both the inner frame 4 and the outer frame 6, and may be arranged on only one of the frames.
In addition, what is arranged inside the inner frame 4 and what is arranged between the inner frame and the outer frame 6 can be appropriately changed. For example, a stairwell is arranged at the center of the floor 1, and a common corridor is arranged around the outer periphery of the stairwell. Then, an inner frame 4 is arranged on the outer periphery of the corridor, and a common facility and a dwelling unit composed of an elevator and stairs are arranged on the outer periphery of the inner frame. further,
The outer frame 6 may be arranged on the outer periphery of the common facility and the dwelling unit.

The seismic isolation device 8 provided at the lower part of the first floor is not limited to the one composed of the laminated rubber and the steel damper, but may be composed of only the laminated rubber. May be configured. Further, the damper is not limited to the steel damper, and may be an oil damper or a lead damper. Further, the seismic isolation device 8 does not necessarily have to be provided.
