Description

The present invention relates to a damping wall that generates a reaction force in response to a linear displacement. In particular, it relates to a damping wall that can respond to changes in the mode of an earthquake.

When an earthquake occurs, target structures such as buildings and structures are shaken horizontally and vertically.
If the acceleration level due to an earthquake or the like is large, the target structure may be damaged, the contents of the target structure may be accelerated more than expected, or the target structure may be displaced more than expected.
Therefore, a seismic isolation device that reduces the vibration energy transmitted from the foundation to the target structure to isolate the vibration, or absorbs the vibration energy when the target structure vibrates and reduces the vibration level to suppress the vibration. Devices with various structures are being tested as vibration isolation devices.
By properly setting the structure and the specifications of the elements that make up the structure, the desired seismic isolation performance and vibration damping performance can be exhibited.
For example, viscous dampers are used for that purpose.

As a viscous damper, a device using an oil damper or a shear resistance of a viscous material is known. An example of the latter is a wall-type damping wall. The damping wall is mainly composed of an outer wall, an inner wall, and a viscous material. The outer wall is flanged to the lower layer and the inner wall is flanged to the upper layer, and the outer wall is filled with a viscous material.
When the structure is deformed between layers, the vibration of the building is suppressed by the shear resistance of the viscous material. Since the vibration energy is converted into heat energy, the temperature of the viscous material rises. The viscous material has temperature dependence and frequency dependence, and has the characteristic that the higher the temperature for the same amplitude width, the lower the frequency and the lower resistance.
In recent years, there has been concern about the occurrence of long-period ground motion, and if these viscous dampers are shaken by vibration for a long period of time, there is a problem that a sufficient vibration suppression effect cannot be obtained due to a decrease in resistance due to temperature.
In addition, since long-period ground motion has a wavelength containing many long-period components (low frequency), there is a problem that a large resistance cannot be obtained.

It flows into the electric circuit and can suppress the shaking.
Further, since the current flowing due to the potential difference generated between the pair of terminals of the piezoelectric element is used as energy for cooling the cooling plate, the building is shaken by an earthquake or the like, and the upper floor structure and the lower floor structure are formed. When a relative displacement occurs between the two, the temperature rise of the viscous body that suppresses the shaking can be suppressed and the decrease of the viscous resistance of the viscous body can be suppressed.

When the above occurs, the outer wall body 100 and the inner wall body 200 are relatively displaced, and the movement of the viscous body causes expansion and contraction displacement of the fourth piezoelectric element member 810 via the fourth metal plate member, so that a pair of the plurality of piezoelectric elements 810a is paired. A potential difference is generated between the terminals of the above, and a current flows through the fourth electric circuit 830, so that shaking can be suppressed.
Further, since the current flowing due to the potential difference generated between the pair of terminals of the piezoelectric element is used as energy for cooling the cooling plate 400, the building is shaken by an earthquake or the like, and the upper floor structure R and the lower floor structure F are used. When a relative displacement occurs between the two, it is possible to suppress the temperature rise of the viscous body that suppresses the shaking and suppress the decrease in the viscous resistance of the viscous body 300.
Further, since the cooling plate 400 is fixed to the side of the third metal plate member 720 or the fourth metal plate member 820 in contact with the viscous body, the building shakes due to an earthquake or the like, and the upper floor structure R and the lower floor structure When a relative displacement occurs with F, it is possible to suppress the temperature rise of the viscous body 300 that suppresses shaking and suppress the decrease in the viscous resistance of the viscous body 300.
Further, a fifth piezoelectric element member 910 having a plate-shaped contour and having a plurality of piezoelectric elements arranged along the plate-shaped upper surface in the contour is sandwiched between the outer wall material and the inner wall material, and the fifth piezoelectric element member. When shear deformation occurs in the horizontal direction along the side surface between the upper surface and the lower surface of the plate-shaped contour of the 910, a potential difference is generated between the pair of terminals of the plurality of piezoelectric elements 910a of the fifth piezoelectric element member 910. Since the fifth electric circuit 930 is electrically connected between the pair of terminals of the plurality of piezoelectric elements, the building shakes due to an earthquake or the like, and a relative displacement occurs between the upper floor structure R and the lower floor structure F. The outer wall body 100 and the inner wall body 200 are relatively displaced, a shear displacement occurs in the fifth piezoelectric element member 910, a potential difference is generated between the pair of terminals of the plurality of piezoelectric elements, and a current is transmitted to the fifth electric circuit 930. It can flow and suppress shaking.
