Abstract
The present invention provides a column-and-beam join structure which absorbs energy caused by a large earthquake or the like by split tees surely yielding at a prescribed value, does not cause other members to fracture, and thus makes it possible to replace only the split tees which have become unusable, and, more specifically, a column-and-beam join structure constructed by attaching and connecting, using bolts the ends of both the upper and lower flanges of a steel beam (H-shaped steel beam) between the webs of a pair of upper and lower split tees the flanges of which are connected to a steel column using bolts The upper limit of the yield stress of the steel material used for the split tees is defined to be not more than twice the lower limit thereof. Further, in order for the web extending from the flange of a split tee in the axial direction of an H-shaped steel beam to absorb earthquake energy by its plasticization, the cross-sectional area of the web is reduced partially and the base end portion of the web is divided from the tip portion which is connected to the flange of the H-shaped steel beam
