PROBLEM TO BE SOLVED: To provide a structure capable of favorably reducing the vibratory response in an earthquake when a structure is constructed on a soft ground or a liquifaction ground. SOLUTION: In a building 1 provided with piles 5,... driven to reach a support layer 2 at the lower end, a substrate structure 6 connected to the upper end 5b of the piles 5 and laid to position in the surface course 3, and the upper structure 7 installed on the substrate structure 6, the substrate structure 6 is formed to be able to obtain a specified buoyancy from the underground water W stagnating in the surface course 3 or the fluidized sand in liquefaction. The piles 5 are formed to have a specified horizontal spring rigidity so as to elastically regulate the horizontal displacement of the substrate structure 6.
