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: A building body support structure 10D supports a building body 16 through a column 14 having a column base part 26 that opens downward on a column base 2402. A resistance mechanism 20D to generate resistance to uplift of the building body 16 while allowing the uplift and generate resistance to drop when the building body 16 drops after uplifting while allowing the drop is provided across a footing beam 12 and the column base part 26. The resistance mechanism 20D comprises: a rod 42 that has a lower small diameter part 4204 and a large diameter part 4206 whose cross section is larger than the lower small diameter part 4204 and is inserted in the column base part 26; and an elastic member 44 in which the lower small diameter part 4204 is penetrated and which is located at a position of the column base part 26 under the large diameter part 4206 and whose outer periphery is attached to an inner peripheral surface 2404 of the column base part 26.SELECTED DRAWING: Figure 1
【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】柱脚２４０２に下方に開放された柱脚部２６を有する柱１４を介して建物本体１６を支持する建物本体の支持構造１０Ｄであって、基礎梁１２と柱脚部２６とにわたり、建物本体１６の浮き上がりに対して浮き上がりを許容しつつ抵抗を生じ、かつ、建物本体１６の浮き上がり後の降下時に降下に対して降下を許容しつつ抵抗を生じる抵抗機構２０Ｄが設けられている。抵抗機構２０Ｄは、下部小径部４２０４と、下部小径部４２０４よりも断面積の大きい大径部４２０６とを有し柱脚部２６に挿入されるロッド４２と、下部小径部４２０４が貫通されて大径部４２０６よりも下方の柱脚部２６の箇所に位置し柱脚部２６の内周面２４０４にその外周部が取着された弾性部材４４とを含んで構成されている。【選択図】図１
