Description

  The present invention relates to a vibration damping device and a building including the vibration damping device.

  Conventionally, in multi-layered buildings such as condominiums and office buildings, a vibration damper installed inside the building absorbs and attenuates seismic energy (vibration energy) that acts during an earthquake, reducing the response of the building. There is. In addition, such damping dampers include hysteresis dampers that use the yield strength of steel materials and frictional resistance of sliding materials, viscous dampers such as oil dampers that use the viscous resistance of viscous materials, and shearing of viscoelastic materials. Viscoelastic dampers that utilize resistance are often used.

  On the other hand, it has been proposed and put into practical use to install a vibration damping device called TMD (Tuned Mass Damper) on the top side of a building (such as a rooftop) to reduce the earthquake response of the building (for example, Patent Document 1, See Patent Document 2).

  Specifically, the TMD is configured as a one-degree-of-freedom vibration system in which a pendulum (weight body (weight)) is attached to an accessory frame and the weight body reciprocally vibrates. By synchronizing the primary natural period of the building and vibrating the weight in the direction opposite to the vibration of the building, that is, by utilizing the inertial resistance force (inertial mass effect) due to the vibration of the weight. , It is possible to attenuate the seismic energy acting on the building and reduce the response of the building.
