Abstract

PROBLEM TO BE SOLVED: To decrease partly increasing earthquake-response values in a layer without oil dampers, by installing oil-dampers in the structural face of every other layer or through multi-layer of a building. SOLUTION: A long hole in which a dowel pin fixed to a brace 3 side is inserted, is bored, in the crossing of braces 3 of every other layer of a building constructed to form a X-shape. The braces 3 are horizontally connected with an oil damper 4 through a bracket so as to hold an auxiliary damper with the brace 3 side along both sides of the long hole. In this time, the braces 3 are assembled to form a V-shape at the upper layer and an inverted V-shape at the lower layer, at the structural face of a column 1 and a beam 2 and both brace heads are connected to each other through the bracket and the damper 4. The dowel pin prevents the deformation at the outside of the structural face of the brace 3 in the long hole and at the same time, the auxiliary dampers arranged at both sides of the dowel pin can bring out the correspondent attenuating effect.

It has been proposed that a plurality of layers of seismic elements are provided, and a damper is interposed between the column-beam frame and the seismic elements or in the middle of the seismic elements to achieve a high vibration suppression effect.

震効果が得られる。[0003] That is, of the structures in which the oil dampers are installed in the building surface, the structure in which two oil dampers are installed in two layers by skipping one layer is installed rather than the structure in which the oil dampers are installed in each layer. However, a large damping effect can be obtained with the same number of oil dampers.

The vertical axis represents the attenuation constant h, and the horizontal axis represents the attenuation coefficient c. The maximum value of the damping constant h is Δh = about 16% in the case of the two-layer oil damper installation structure, and can be expected to increase more than Δh = about 12% in the case of the oil damper installation structure of each layer.

答を低減することを課題とする。However, since a layer to which the oil damper does not contribute occurs one layer at a time, the seismic response value of that layer may increase locally. This tendency is more remarkable when the oil dampers are installed in a multi-layer structure. SUMMARY OF THE INVENTION The present invention has been made in view of the above problem, and it is an object of the present invention to reduce a seismic response of a layer in which a damper is not arranged in a damper arrangement structure in which one layer has two layers.

The main purpose is the seismic control structure of the non-installed layer in the installation of the two-layer oil damper characterized by the following.

前記ブレースを接合してなる構造とする。[0008] Specifically, at the intersection of the two-tiered braces of the building forming the X-shape, a slot is inserted through which a dowel pin fixed to the brace is inserted, and along the both sides of the slot. An auxiliary damper is arranged, and the brace is horizontally joined to the brace by an oil damper via a bracket that sandwiches the auxiliary damper with the brace side.

きる。FIG. 2 is a diagram showing the results of complex eigenanalysis in the case of a two-layer damper installation structure and each layer damper installation. The damping constant h in the two-layer oil damper installation is:
The increase can be expected more than in the case of each layer oil damper installation structure.

揮していることがわかる。FIG. 3 is a graph comparing the maximum seismic response acceleration when the two-layer oil damper is installed, when the auxiliary damper is provided as in the present invention, and when the auxiliary damper is not used. The vertical axis represents each floor of a ten-story building as shown in FIG. 1, and the horizontal axis represents response acceleration. As can be seen from the figure, among the 1, 3, 5, and 7 layers in which no damper is provided (layers without beams), the structure in which the auxiliary damper is not provided has a larger maximum response acceleration. In other words, it can be seen that the auxiliary damper exerts a corresponding damping effect.

Therefore, as shown in FIG. 5 (a), a bracket 9 is provided so as to sandwich the viscoelastic damper 7 with a bracket 9 having a horizontal elongated hole 8 drilled in the brace structure through which the dowel pin is inserted. The oil damper 4 is mounted horizontally in the brace structure.

The viscoelastic dampers 7 as auxiliary dampers disposed on both sides of the dowel pin 6 can reduce the seismic response of the layer where the locally increased beams are skipped, while suppressing deformation outside the brace structure. . Here, it goes without saying that the relationship between the dowel pin and the elongated hole through which the dowel pin is inserted may be reversed.

ができる。It has been found that a structure in which an oil damper is provided through two layers with one layer skipped has a higher damping effect than a structure in which an oil damper is provided in each layer. However, in this case, the seismic response locally increases in the layer where the oil damper is not installed. By using the auxiliary damper of the present invention, it is possible to suppress an input response that locally increases due to minor treatment.
