Abstract
In a boiler support structure in which certain seismic isolators are provided with a pullout countermeasure, the seismic isolators to be provided with the pullout countermeasure are individually identified according to whether the seismic isolator satisfies Formula (1): N+N>N. . . Formula (1), where N(N<0) is a compressive load occurring on each of the seismic isolators and calculated on the basis of a permanent load imposed on the boiler support structure; N(N>0) is a pullout force occurring on each of the seismic isolators and calculated on the assumption that an earthquake has occurred; and N(N>0) is an allowable pullout force of each of the seismic isolators and calculated using an allowable pullout stress of each of the seismic isolators.
