To provide a base isolation building in which a base isolator is disposed inside a base isolation pit including a retaining wall and a substructure of the building is supported by the base isolator so that the base isolation building can suppress impact when the retaining wall collides with the substructure during an unexpected extremely great earthquake, while almost ensuring a designed relative horizontal displacement amount of a clearance set between the retaining wall and the substructure.SOLUTION: A base isolator 35 is installed inside a base isolation pit 30 having a foundation batholith 10 and a retaining wall 20 erected on a circumference of the foundation batholith 10, and a substructure 40 of a building is supported by the base isolator 35, and a first clearance is disposed between the retaining wall 20 and the substructure 40 in a base isolation building 70. The retaining wall 20 has at least an outer face material 21 provided for earth retaining and a plurality of stiffeners 23 disposed at intervals in a horizontal direction on an inner surface 21a facing the inside of the base isolation pit 30 on the outer face material 21.SELECTED DRAWING: Figure 2
【課題】擁壁を含む免震ピットの内部に免震装置が配置され、免震装置にて建物の下部構造体が支持されている免震建物に関し、擁壁と下部構造体の間に設定されている隙間が設計相対水平変位量を概ね確保しながら、想定外の極大地震時において擁壁と下部構造体が衝突した際の衝撃を抑制することのできる、免震建物を提供すること。【解決手段】基礎底盤１０と、基礎底盤１０の周縁に立設している擁壁２０と、を備えている免震ピット３０の内部に免震装置３５が設置され、免震装置３５にて建物の下部構造体４０が支持され、擁壁２０と下部構造体４０の間に第１隙間が設けられている、免震建物７０であり、擁壁２０が、山留めに供される外側面材２１と、外側面材２１における免震ピット３０の内部に臨む内側面２１ａにおいて、水平方向に間隔を置いて設けられている複数の補剛材２３とを少なくとも有する。【選択図】図２
