Abstract

PURPOSE:To provide a high damping building which is more reasonable and excellent in vibration restraining effect by using a damping device having a characteristic of which relation between speed and load generated in the device is nearly linear, and thinking about arrangement of the damping devices against the building frame CONSTITUTION:In a multistory building frame 1 consisting of pillars 2, beams 3, and the like, reverse V-shaped braces 5 as earthquake proofing elements are provided through every two stories, and the top part of the brace 5 is connected to the beams 3 through a damping device 10. The characteristic of the damping device 10 is set so that speed and load generated in the device are nearly in linear relation, and a decided damping coefficient(c) is given to the building frame. By the constitution in which the braces 5 are provided through every two stories and the damping devices are arranged on every other story, the peak of a primary damping constant is attained by a smaller damping coefficient and a large damping constant can be obtained, compared with the case in which an earthquake proofing element and damping device are provided on every story. Further, variation of the primary natural period is sensitive against variation of damping coefficient, and variation of period becomes steep.

The conventional active damping system of the type incorporating a variable stiffness element mainly focuses on the relationship between the predominant period such as earthquake motion and the natural frequency of the structure. On the other hand, by actively shifting the natural frequency of the structure, the resonance phenomenon is avoided and the response amount is reduced.

However, in the case of an active vibration control system, in addition to a control computer, a driving device and various sensors are used, so that various safety maintenance mechanisms are required in case of any abnormality. The control mechanism becomes complicated,
There may be a cost problem. In addition, there may be a case where it takes time to exert a sufficient effect due to a control delay.

On the other hand, a damping device as a damper is installed in the column / beam frame, and the damping coefficient c (t / kine) of the damping device is installed.

In this case, the optimum damping coefficient c differs depending on whether the target external force for vibration reduction is an earthquake or a wind external force. For example, swaying of structures due to wind is a frequent occurrence on a daily basis, and especially in high-rise buildings, where the natural period becomes long, large swaying of long periods is likely to occur due to wind, causing seasickness. There is. Such a sway of the building due to the wind is dominated by the primary vibration mode of the building, and in the case where the relationship between the speed and load generated in the damping device is set to be substantially linear, the larger the damping constant h, the larger the building constant. Response is reduced. Further, the greater the rigidity of the building (shorter period), the smaller the shaking. In contrast,
When considering a comparatively large-scale earthquake as a target for vibration reduction, the optimum damping coefficient c has a smaller value than the optimum damping coefficient c for the wind external force.

On the other hand, when an optimum damping coefficient c is given to these external forces, a general damper conventionally used for various purposes has a small damping coefficient, and the optimum damping coefficient in a building is required. In order to realize c, there is a problem that the number of devices becomes too large, which makes it difficult to design a building. In particular, for the purpose of reducing wind vibration, the damping coefficient c is set in a range where the rigidity of the building is high and the primary natural period is short.
In general, the optimum damping coefficient c has a considerably large value, so that it is often difficult to design the device and the layout thereof. The present invention intends to solve the above-mentioned problems by devising the arrangement of a damping device in a passive vibration control system that does not require a control system based on a computer program or the like.

In the graph of FIG. 5, the broken line represents the case of the comparative example of FIG. 4 (a), and as shown by the curve of a (T 1 ), as the damping coefficient c increases, the natural period of the building ( In this graph, only the first natural period is shown).

With respect to the damping characteristics in the comparative example of FIG. 4 (a), the brace 5 (or 6 and 7) extending over two layers is provided while the rigidity k remains unchanged, and the damping devices are arranged every other layer. In the example of b), as shown by the curve of b (T 1 ), the change of the primary natural period becomes sensitive to the change of the damping coefficient, and the period change becomes sharp. Therefore, a
As is clear from comparison with the curve of (T 1 ), the selection range of the damping coefficient c can be narrowed down, and the damping force generated in the damping device can be reduced because the damping coefficient c stabilizes on the short cycle side with a smaller damping coefficient. And the design is easy. Alternatively, reducing the number of installed damping devices facilitates the design of the building frame.

Therefore, even with respect to seismic motion, the design of the damping device is easy as in the case of wind vibration, the number of installed damping devices can be reduced, and a high damping property can be given to the building.

In the case of the embodiment of FIG. 4 (c) in which the rigidity of the brace 5 (or 6 and 7) is halved compared to the embodiment of FIG. 4 (b), the curves c (T 1 ) and b ( T 1 ) and the curve c (h
As is clear from the comparison between 1 ) and b (h 1 ), although the steepness of the period change and the value of the first-order damping constant h 1 at the peak are inferior, the 1st natural period shifts to a shorter period, and 1
The damping coefficient that gives the peak of the next damping coefficient h 1 is shown in Fig. 4 (b).
Since the value is smaller than that of the embodiment, it is advantageous for the design of the mechanism of the damping device itself and its arrangement. Further, since the optimum damping coefficient for suppressing the vibration becomes smaller, the difference between the optimum damping coefficient for the wind vibration and the optimum damping coefficient for the seismic motion also becomes smaller, and it becomes easy to deal with both.
