免震構造物

Japanese Patent JP7145669

B2

To provide a seismic isolation structure having higher seismic isolation performance without being affected by a structure type of a core part, and capable of coping with larger earthquake vibration.SOLUTION: A seismic isolation structure comprises: a core part 1; a building main part 2 adjoining the core part; a double-layer seismic isolation structure having a foundation seismic isolation layer 3 formed below the core part and the building main part; and an intermediate seismic isolation layer 4 formed at an intermediate part of the building main part. The core part of an upper layer rather than the intermediate seismic isolation layer, and an upper frame 2a of an upper layer rather than the intermediate seismic isolation layer of the building main part are integrally formed, the core part of a lower layer rather than the intermediate seismic isolation layer, and a podium frame 2b of a lower layer rather than the intermediate seismic isolation layer of the building main part are independently formed, and a wall part of the core part of the upper layer rather than the intermediate seismic isolation layer is lower in rigidity than a wall part of the core part of the lower layer rather than the intermediate seismic isolation layer.SELECTED DRAWING: Figure 1
