BUILDING BODY SUPPORT STRUCTURE
To prevent excessive uplift of a building body during earthquake and reduce an impact occurring when the uplifted building body drops.SOLUTION: When earthquake is detected by an earthquake detecting section 38, a friction member 34A is expanded by charging air in a fluid chamber 42A to perform a pressure control to press an outer peripheral surface 3406 of the friction member 34A against an inner peripheral surface 2404 of a column base 2402. When the earthquake vibration reaches a ground directly under a building body 16, a large horizontal force is applied to the building body 16, and the moment causes the building body 16 to tilt so as to displace one side of the building body 16 in an uplifting direction. A friction resistance is generated between the outer peripheral surface 3406 of the expanded friction member 34A and the inner peripheral surface 2404 of the column base 2402, and a resistance to upward displacement of the building body 16 is generated.SELECTED DRAWING: Figure 2
【課題】地震時の建物本体の過大な浮き上がりを抑制し、かつ、浮き上がった建物本体が降下する際の衝撃を緩和する。【解決手段】地震検知部38により地震が検出されると、流体室42Aに空気を充填させることで摩擦部材34Aを膨張させ、摩擦部材34Aの外周面3406を柱脚2402の内周面2404に圧接させる圧接制御を実施する。地震動が建物本体16の直下の地盤に到達すると、建物本体16に大きな水平力が作用し、そのモーメントにより建物本体16が傾動し、建物本体16の一側が浮き上がる方向に変位しようとする。膨張した摩擦部材34Aの外周面3406と柱脚2402の内周面2404との間に摩擦抵抗が生じ、建物本体16の上方への変位に対しての抵抗を生じる。【選択図】図2
