Title:
ARTIFICIAL GROUND STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/029070
Kind Code:
A1
Abstract:
The present invention provides an artificial ground structure comprising support piles with a large amount of protrusion from the ground and exhibiting improved seismic resistance by absorbing energy through plastic deformation of the support piles in response to vibrations from a major earthquake. An artificial ground structure according to the present invention comprises support piles driven into the ground in parallel to a first direction in which an artificial ground extends and a second direction intersecting the first direction, upper panel points set at the upper ends of the support piles, first girder members connecting adjacent two upper panel points, and a floor plate set above the upper panel points and the first girder members. The support piles are set such that a history curve between a horizontal displacement and a horizontal load, which are exhibited at the time of a level-2 seismic motion, has a spindle shape.
