BUILDING BODY SUPPORT STRUCTURE
To prevent excessive uplift and damage of columns of a building during earthquake and reduce an impact occurring when the uplifted building body drops.SOLUTION: When earthquake occurs and is detected by an earthquake detecting section 38, a friction member 34 is expanded by charging air in a fluid chamber 42 to perform a pressure control to press an inner peripheral surface 3412 of the friction member 34 against an outer peripheral surface 3204 of a rod 32. 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 inner peripheral surface 3412 of the expanded friction member 34 and the outer peripheral surface 3204 of the rod 32, and a resistance to upward or downward displacement of a column 14 of the building is generated.SELECTED DRAWING: Figure 2
【課題】地震時の建物の柱の過大な浮き上がりや損傷を抑制し、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】地震が発生した場合、地震検知部３８により地震が検出されると、流体室４２に空気を充填させることで摩擦部材３４を膨張させ、摩擦部材３４の内周面３４１２をロッド３２の外周面３２０４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３４の内周面３４１２とロッド３２の外周面３２０４との間に摩擦抵抗が生じ、建物の柱１４の上方、下方への変位に対しての抵抗を生じる。【選択図】図２
