COLUMN BASE JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a column base joint structure of a building with a plurality of layers, which reduces flexural strength to avoid stress concentration on a lowermost layer and which suppresses a reduction in other kinds of strength.SOLUTION: A column base joint structure (2) of a building with a plurality of layers comprises a foundation structure (4) of reinforced concrete construction, and a column (6) of reinforced concrete construction, which is erected in a foundation beam structure. The column has a first column reinforcement (12) that is connected to the foundation structure and extended in a vertical direction, and a second column reinforcement (14) that is extended in the vertical direction without being connected to the foundation structure. A detailing member (20) having a laminated structure of a rubber plate (24) and a steel plate (26) is arranged between a top surface of the foundation structure and an undersurface of the column.SELECTED DRAWING: Figure 1
【課題】最下層への応力集中を回避するために曲げ耐力を減少させ、かつ他の耐力の減少が抑制された複数層を有する建築物の柱脚接合構造を提供する。【解決手段】複数層を有する建築物の柱脚接合構造（２）は、鉄筋コンクリート造の基礎構造物（４）と、基礎梁構造物に立設された鉄筋コンクリート造の柱（６）とを備える。柱は、基礎構造物に連結されて鉛直方向に延在する第１柱筋（１２）及び基礎構造物に連結されずに鉛直方向に延在する第２柱筋（１４）を有する。ゴム板（２４）と鋼板（２６）との積層構造を有する納まり部材（２０）が、基礎構造物の上面及び柱の下面間に配置される。【選択図】図１
