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 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. 5A, a bracket 9 is provided so as to sandwich the viscoelastic damper 7 with a bracket 9 having a horizontal elongated hole 8 formed in a 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 pins 6 can reduce the seismic response of the layer that has skipped the locally increased beam 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.
