Abstract
A floating-type base isolation system includes: a liquid storage portion storing liquid; a floating structure floated and arranged on the liquid; and a gas accommodation space formed at a position in contact with the liquid and accommodating gas. A volume of the gas accommodation space is set based on a natural frequency of a system that responds to a seismic wave propagating in fluid including the liquid and the gas.
