Document Type and Number:
Japanese Patent JP2012202510
Kind Code:
A
Abstract:
To reduce vibration responses in the vertical direction of a building installed via a base isolation device.
A base isolation structure includes: a foundation plate 5 supported on a floor 3 via the base isolation device 4; a main structure 6 connected integrally on the foundation plate 5; and a mass damper 7 for generating second vertical vibration for suppressing the vibrations of the main structure from first vertical vibrations input via the foundation plate 5.
