COLUMN BASE JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a structure capable of reducing the flexural rigidity of a column base joint part and suppressing the occurrence of biting and vertical crack at the vicinity of the bottom edge of column for avoiding stress concentration to an undermost layer upon an earthquake, in a column base joint structure of a reinforced-concrete made building having plural layers.SOLUTION: A column base junction structure (10) is erected on a base structure such as footing (11) or the like, and a column (12) comprises first main reinforcements (18) coupled to the base structure and second main reinforcements (19) not coupled to the base structure. The column extends with a constant cross-sectional profile into the vertical direction in an intermediate part (14) and extends with a decreased cross-section than the intermediate part, in a bottom edge part (15). A height of the bottom edge part is 0.3 to 1.5 times a width of the intermediate part, and the bottom edge part has a taper part (16) which is tapered downward.SELECTED DRAWING: Figure 1
【課題】複数層を有する鉄筋コンクリート造の建物の柱脚接合構造に於いて、地震時の最下層への応力集中を回避するために柱脚接合部の曲げ剛性を減少させるとともに、柱の下端近傍におけるめり込みや縦ひび割れの発生を抑制できる構造を提供する【解決手段】柱脚接合構造(10)は、フーチング(11)等の基礎構造物上に立設され柱(12)は、基礎構造物に連結された第1主筋(18)と、基礎構造物に連結していない第2主筋(19)とを有する。前記柱は、中間部(14)に於いては鉛直方向に一定の横断面輪郭で延在し、下端部(15)に於いては中間部よりも横断面が縮小されている。下端部の高さは、前記中間部の幅の0.3倍〜1.5倍であり、下端部は下方に向かって先細のテーパー部(16)を有する。【選択図】図1
