2. Description of the Related Art As is well known, as a form of a middle and high-rise apartment building, each dwelling unit is divided by a boundary wall provided along the beam-to-beam direction, which has a long flat shape in the girder direction. Commonly referred to as the "plate form") is the most common. In the building with the above-mentioned form, the boundary walls are formed as earthquake-resistant walls, and the earthquake-resistant walls are installed continuously on the upper and lower floors, and a series of such earthquake-resistant walls (multi-layered earthquake-resistant walls) is used to counter the earthquake force The structural form is usually adopted.

[0003]

By the way, in a building of a structural type having the above-mentioned multi-layered earthquake-resistant wall, the higher the building is, the larger the overturning moment is applied to the legs of the multi-layered earthquake-resistant wall during an earthquake. Therefore, the foundation must be capable of coping with the pull-out force due to such a fall moment, which naturally limits the increase in height.

In view of the above circumstances, it is an object of the present invention to provide an effective structure capable of reducing the overturning moment acting on the foundation part, thereby simplifying the foundation part and increasing the height of the building.

1 to 3 show a first embodiment of the present invention. The building of the first embodiment is an apartment house of a middle or higher level, and its plan shape is long in the girder direction, and a large number of boundary walls 1 along the beam-to-beam direction are arranged at predetermined intervals on each floor. Each dwelling unit 2 is divided by the door boundary walls 1, and a shared corridor 3 and a balcony 4 which is a dedicated space for each dwelling unit 2 are provided on both outer peripheral sides.
Has been provided. The above mentioned boundary wall 1 is provided as an earthquake resistant wall, and as shown in Fig. 1, these boundary walls 1 form a continuous multi-layered earthquake resistant wall. The seismic wall 1 of this resists the seismic force.

The above construction is common to the conventional general plate-shaped apartment house, but in addition to the above construction in this building,
An outer peripheral frame 7 composed of columns 5 and beams 6 is provided along the girder direction on the outer peripheral portion on the balcony 4 side, and the outer peripheral frame 7 and the series of earthquake-resistant walls (door boundary wall 1) are provided via a column 9. It is connected by a damper 8. As the damper 8, a steel material damper that absorbs vibration energy and attenuates vibration by plastic deformation of the steel material is used. The steel dampers 8 may function as support beams for the balcony 4, and in this example, a large number of steel dampers 8 are provided for each span on each floor.

In the above structure, as shown in FIG. 3, when a building vibrates and a bending deformation occurs in the beam-to-beam direction during an earthquake, a series of earthquake-resistant walls (the boundary wall 1) and the outer peripheral frame 7 are vertically moved. Will be displaced relative to the
Undergoes plastic deformation to absorb the vibration energy and quickly damp the vibration. As a result, the deformation of the entire building is suppressed, and the overturning moment acting on the foundation is also reduced. Therefore, the foundation can be simplified and a high-rise building of this type can be realized.

4 and 5 show a second embodiment of the present invention. The building according to the second embodiment is an apartment house similar to the building according to the first embodiment, and the boundary wall 1 constitutes a multi-story earthquake-resistant wall.
The damper 8 is provided between the (seismic wall) and the body of the core portion 10.

That is, in this building, as shown in FIG. 4, a core portion 10 connected to the common corridor 3 is provided, and a staircase and an elevator are installed therein. The core part 10 is structurally independent of the dwelling part (the dwelling unit 2 and the common corridor 3), and the boundary wall 1 facing the core part 10 has pillars 9 on each floor as shown in FIG. The core 8 is connected to the connecting beam 10a on the shared corridor side by the damper 8. The damper 8 according to the second embodiment is also a steel damper similar to that according to the first embodiment, and may also serve as a support beam for the shared corridor 3. In addition,
As shown in FIG. 6, the two dampers 8 may be installed obliquely so as to be connected to the outer walls 10b on both sides of the core portion 10, or as shown in FIG. 7, the pillar 9 and the outer wall of the core portion 10 may be installed. Connecting beams 11 and 12 are provided on 10b, and connecting beams 1 are provided.
It is also possible to connect the outer wall 10b of the core portion 10 and the boundary wall 1 (shakeproof wall) with the damper 8 via the columns 1 and 12 and the pillar 9.

In the second embodiment, the housing part and the core part 10 behave differently during an earthquake and are displaced relative to each other in the vertical direction, so that the damper 8 operates to absorb the vibration energy. The same effect as the form is obtained.

The damper 8 in the first and second embodiments is not limited to the steel damper, and the vertical relative surface between the boundary wall 1 as an earthquake resistant wall and the outer peripheral frame 7 or the core portion 10 is not limited. Other types of dampers, such as a viscous damper, a viscoelastic damper, an oil damper, etc., can be adopted as long as they operate when displacement occurs. Further, in the first embodiment, the damper 8 is not necessarily provided in each span in each floor, and in the second embodiment, the damper 8 is not necessarily provided in each floor, and in any case, a desired damping force can be obtained. It should be arranged optimally.

Further, the present invention is most rational to be applied to an apartment building, but the use and scale of the building, the plan, etc. are not particularly limited as long as the present invention can be applied. For example, in the first embodiment, the outer peripheral frame 7 is provided on the balcony 4 side and the damper 8 also serves as a support beam for the balcony 4, but instead of or in addition to this, the outer peripheral frame 7 is provided on the common corridor 3 side. It is also possible to provide the damper 8 as a support beam for the shared corridor 3 provided in the. Further, in the second embodiment, the core portion 10
Although the staircase and the elevator are provided in the above, the elevator may be omitted in a low-rise building that does not require the elevator, and of course, another common space may be provided in the core portion 10 if necessary.

[0017]

As described above, according to the first aspect of the present invention, since the series of earthquake-resistant walls and the outer peripheral frame are connected by the damper, the damper is activated when the building vibrates during the earthquake and they are vertically displaced relative to each other. As a result, the vibration energy is absorbed and the vibration is quickly dampened. As a result, the deformation of the entire building is suppressed, and the overturning moment acting on the foundation is reduced. Therefore, simplification of the foundation and high-rise building can be realized without problems. be able to. Further, the invention of claim 2 is applied to an apartment house, the earthquake-resistant wall is used as a boundary wall, the outer peripheral frame is arranged at the tip of the balcony, and a steel material damper that also functions as a balcony supporting beam is adopted. It is rational and optimal because each of these members can be arranged so as to conform to the form and function required for an apartment house.

According to the invention of claim 3, since the frame of the core part and the earthquake-resistant wall are connected by the same damper, the damper operates in the same manner at the time of an earthquake, and the same effect can be obtained. Since a staircase and an elevator are installed in the core part of the house and a steel damper is installed as the damper and installed on top of the shared corridor, it is ideal for use in a shared corridor type housing complex.
