BASE-ISOLATED BUILDING AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a base-isolated building capable of exerting excellent base isolation performance in case of a large earthquake while suppressing large residual displacement of an upper structure by wind load, without applying wind resistance pins which are shear-fractured in a large earthquake.SOLUTION: A base-isolated building 100 is composed of an upper structure 20 and a lower structure 10. Sliding bearings of different forms are placed between the upper structure 20 and the lower structure 10, and the sliding bearings of different forms are composed of spherical surface slide bearings 30 and plane surface slide bearings 40. A friction factor of the plane surface slide bearing 40 is larger than the friction factor of the spherical surface slide bearing 30.SELECTED DRAWING: Figure 1
【課題】大地震時にせん断破壊される耐風ピンを適用することなく、風荷重による上部構造体の大きな残留変位を抑制しながら、大地震時における優れた免震性能を発揮することのできる免震建物を提供すること。【解決手段】上部構造体２０と下部構造体１０から構成される免震建物１００であって、上部構造体２０と下部構造体１０の間に異なる形態の滑り支承が介在しており、異なる形態の滑り支承は球面滑り支承３０と平面滑り支承４０から構成されており、平面滑り支承４０の摩擦係数は球面滑り支承３０の摩擦係数よりも大きい。【選択図】図１
