MULTISTORIED BASE-ISOLATED STRUCTURE
PROBLEM TO BE SOLVED: To provide a multistoried base-isolated structure capable of effectively reducing response acceleration when an earthquake occurs in a skyscraper.SOLUTION: A multistoried base-isolated structure for use in a building B formed in a multistoried shape includes: a lower base isolation layer 20 that is provided on the foundation side of a lower part of the building B; and an upper base isolation layer 30 that is provided between a foundation-side lower structure part 10 formed by dividing many stories of the building B by a predetermined number of stories and an upper structure part 11 formed on the upside of the lower structure part 10. The upper base isolation layer 30 comprises a slope slide device and an attenuation device such as an inertial mass damper.SELECTED DRAWING: Figure 1
