The present invention relates to a vibration control building composed of a vibration control device to be borne. The use of the seismic control building is not particularly limited, but is suitable for use as, for example, a medium- and low-rise precision factory building, an office, or an apartment building.

  Conventionally, as a prior art classified as a so-called connected seismic control building among seismic control buildings, for example, “the seismic reinforcement structure of an existing building” disclosed in Patent Document 1 below, or disclosed in Patent Document 2 Attention is paid to “seismic structures” and “seismic buildings” disclosed in Patent Document 3.

The “seismic damping reinforcement structure of the existing building” disclosed in Patent Document 1 is a structure in which the damping frame is constructed independently in a place where it does not interfere with the existing building, and this is connected to the existing building to strengthen the damping. Yes, with the aim of seismic reinforcement with existing buildings in use.
The “seismic structure” disclosed in Patent Document 2 is a substructure that is structurally separated and independent from a super high-rise building or tower structure (steel structure), and is connected by a damping device.

The prior art disclosed in each of the above-mentioned patent documents 1 to 3 is independent from the original building part, and constructs an independent seismic frame, substructure or core tower that bears the horizontal force, and builds it. It is common in the structure which connects a part with a damping device and a damping element.
However, the vibration control frame of Patent Document 1 is constructed in a tower structure that is independent outside or inside an existing building.
Even if it is a substructure of patent document 2, it is still constructed | assembled as an independent tower structure in the exterior or inside of a main body structure.
Furthermore, the core tower of patent document 3 is also a structure which arrange | positions the independent residence block in the outer periphery.
However, even if a high-strength material is used to construct such a vibration control frame, substructure or core tower, or the structure is devised to be a large-scale, high-strength structure, there are limitations in terms of mechanical and installation space and shape. Therefore, it is difficult to implement such a structure that sufficiently satisfies the short-period structural function with high yield strength.

  It is an object of the present invention to construct an outer shell structure part having a high strength with a separated and independent short period structure in an arrangement surrounding the outer periphery of the building part having a long period structure. It is connected with a seismic control device to increase the effect of the connected seismic control by transmitting the horizontal force such as earthquakes acting on the building part to the outer shell structure part, and the outer shell structure is especially built. If it is constructed in a closed shape that surrounds the outer periphery of the part, it is easy to build a short cycle structure with high strength and light weight by taking advantage of its shape effect, and if the building part supports only its own weight and long-term vertical load by that much It is sufficient to provide a seismic control building that can be constructed in a long-period structure with low horizontal rigidity.

As a means for solving the above-mentioned problem, the vibration control building according to the invention described in claim 1 is:
Self-weight and supports the long vertical load weight, always with architectural part 1 of the long period structure which forms the main part of the building to be subjected to use, the construction parts the construction part 1 constructed separated in an arrangement surrounding the outer periphery of 1 said shell structure also an outer shell structure portion 2 of high strength in a short periodic structure, and the horizontal force of an earthquake or the like acting on the building portion 1 and the outer shell structure portion 2 and the building part 1 by connecting from while burden communicated to part 2 is composed of a vibration control device 10 for energy absorption and Kanade passively Damping action,
The outer shell structure portion 2 is formed in a closed wall shape that surrounds the outer periphery of the building portion 1 without covering the upper portion of the building portion 1, and to the lattice structure 5 or 6. It is composed of a horizontal structure 7 that integrates continuously or discontinuously to increase the horizontal rigidity of the lattice structure 5 or 6, and is constructed in a short-period structure that is lighter than the building part 1 . It is characterized by that. Most of the horizontal proof stress and horizontal rigidity of the entire building is borne by the outer shell structure portion 2.

The invention described in claim 2 is the vibration control building according to claim 1,
It said shell structure part 2, continuous said a lattice structure 5 or 6 built into a closed-type wall shape surrounding the periphery of the building portion without covering the upper building part 1, into the lattice structure 5 or 6 composed or discontinuously to integrated allowed in a horizontal structure 7 to increase the horizontal stiffness of the lattice structure 5 or 6, and a Oh filter word unit 8 supplementary part to be subjected to construction equipment and vertical stepping rotary line is characterized in that it is constructed in lightweight short period structure in comparison with the construction part 1. The tower section 8 is provided with an elevator room, a staircase, an equipment shaft, and the like.

The invention described in claim 3 is the damping building according to claim 1,
The building portion 1 has a low horizontal rigidity with an axial force column 3 bearing its own weight and a long-term vertical load, and utility floors 4 joined to the axial force column 3 and spaced apart in the vertical direction. It is comprised by the periodic structure, The space | interval of the said upper and lower utility floors 4 and 4 has the height which can accommodate a multilayered infill.

The seismic control building of the present invention is configured so that the outer shell structure portion 2 is formed in a closed wall shape in plan view in an arrangement that surrounds the outer periphery of the building portion 1 without covering the upper portion of the building portion 1. Basically, it is advantageous to construct a short cycle structure with high yield strength and high rigidity. In addition, the outer shell structure portion 2 includes a lattice structure 5, 6 constructed in a closed wall shape, and a lattice structure 5, 6 that is integrated continuously or discontinuously into the closed wall lattice structure 5, 6. supplementary part to be subjected to the horizontal structure 7, or building equipment and vertical stepping rotary line increase the horizontal stiffness of the structure 5 or 6 (elevator chamber, stairwells, etc.) so configured by placing der filter word unit 8, It can be constructed in a short cycle structure with high strength and relatively thin and light weight, and it is a structure excellent in the ability to bear horizontal forces such as earthquakes acting on the building part 1.
On the other hand, the building part 1 surrounded by the outer shell structure part 2 is connected by the vibration control device 10 over the entire circumference, and a horizontal force such as an earthquake acting on the building part 1 is applied to the outer shell structure part. Since it is possible to design and select the appropriate position, direction and quantity to obtain the damping effect while transmitting to 2 Excellent seismic control and seismic control effect.

As a result, building parts 1, long period structure just sufficient to support the weight and long vertical load weight, in other words this building volume, low structures horizontal rigidity the majority of the building weight, specifically Removes as much seismic elements as possible, and the axial force column 3 that supports its own weight and long-term vertical load can be constructed in a long-period structure in which at least one of the column base and the column head is a pin structure. And the damping device 10 has the outstanding connection damping effect using the special difference of the vibration property of the building part 1 of a long period structure, and the outer shell structure part 2 of a short period structure.
Therefore, when this seismic control building is damaged by a large earthquake, the outer shell structure part 2 that bears most of the horizontal strength is damaged, but the building part 1 that is the main part of human activities is not damaged, Can stand on its own. Moreover, the response acceleration at the time of an earthquake is large in the short-cycle outer shell structure part 2, but is small in the long-period building part 1. Thus, since it is the structure which limited and isolate | separated the damage part and the part with a large response acceleration to the outer-shell structure part 2, the living property in the building part 1 at the time of an earthquake and the soundness of a building function can be ensured and ensured. And since the damage at the time of a big earthquake damage concentrates on the outer shell structure part 2, the ease of reinforcement and repair, and maintainability will improve compared with a normal building.

In addition, the vertical space between the utility floors 4 and 4 on the upper and lower floors is configured to have a height (usually 2 to 3 floors at the height of the building) that can accommodate the multi-layer floor infill. The power column 3 is a long column, and its horizontal rigidity is low. A skeleton infill structure in which production processing machines / equipment necessary for housing blocks and factory functions are installed in the high floor space can be formed. Alternatively, only a part of the vibration control building can be implemented as a skeleton infill structure.
On the other hand, the structure of the seismic control building according to the present invention is not limited to the case of implementing as a new building. In the seismic retrofit of an existing building, the outer shell structure part 2 is constructed on the outer periphery of the existing building to control the existing building. By connecting with the vibration device 10, there is no problem in reducing the horizontal rigidity of the existing building by removing seismic elements such as braces and bearing walls. Also suitable.
Building part 1, because it is long-period structure supporting the self-weight and long vertical load weight, use as dwellings as well, it becomes rather suitable for use as a precision factory buildings hating vibration.

Seismic building of the present invention is to support its own weight and long vertical load weight, and building part 1 of the long period structure which forms the main part of the building to be subjected at all times of use, are separated in an arrangement surrounding the outer periphery of the building part 1 and the architectural partial shell structure portion 2 of high strength in a short period structures than 1 constructed Te, and the building part 1 and the outer shell structure portion 2 and the seismic acting on the building portion 1 connects the like the horizontal forces and Kanade passively Damping action while burden communicated to said shell structure part 2 composed of a vibration control device 10 for energy absorption.
It said shell structure part 2, continuous said a lattice structure 5 or 6 built into a closed-type wall shape surrounding the periphery of the building part 1 without covering the upper building part 1, into the lattice structure 5 or 6 The horizontal structure 7 which increases the horizontal rigidity of the lattice structure 5 or 6 by integrating the lattice structure 5 or 6 in an integrated or discontinuous manner, and incidental parts (elevator room, staircase room, equipment shaft room) used for building equipment and upper and lower floor flow lines etc.) constituted by a der filter word unit 8, constructed in a lightweight short period structure in comparison with the construction part 1.
The building part 1 is a long-period structure with low horizontal rigidity, which is composed of an axial force column 3 that bears its own weight and a long-term vertical load, and utility floors 4 that are joined to the axial force column 3 and spaced apart in the vertical direction. Configure. The space between the upper and lower utility floors 4 and 4 has a height that can accommodate a multi-storey infill (the height of a normal building is 2 to 3 floors high).

Reference numeral 1 denotes a building part used for the original purpose of residence, precision factory building or other buildings. Reference numeral 2 denotes a high-strength outer shell structure part constructed so as to be separated from the building part 1 in a closed wall-like arrangement in plan view so as to surround the outer periphery of the building part 1.
2A and 2B conceptually show different examples of the layout plan of the above-mentioned seismic control building. FIG. 3 conceptually shows a vertical sectional view of the damping building.
2A and 2B show the planar shape of the above-mentioned seismic control building as a “rice ball shape”, this is not restrictive. The elliptical shape shown in FIGS. 5A to 5D may be used, and it may be a circle, a polygon, a triangle, a quadrangle, or the like.
