Abstract
In a column end joint structure for joining an end of a column made of flat wooden material having a rectangular cross-section to a joining member, splitting generation at the end of the column is controlled. An expansion of crack is controlled when splitting generated. A cutout portion is provided in each of ends in a longitudinal direction of a column end face, and a joint fitting is coupled inside the cutout portion by a joint bolt. The joint fitting is coupled to a foundation by an anchor bolt. Joint fittings are arranged in the longitudinal direction of the end face inside each cutout portion. One joint fitting is located contacting or close to a surface of the column inside the cutout portion such that the joint fitting side face and the surface of the column inside the cutout portion restrain a displacement orthogonal to the column axis.
