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 9, the ends 8a of both the upper and lower flanges 8 of a steel beam (H-shaped steel beam) 7 between the webs 6 of a pair of upper and lower split tees 4 the flanges 5 of which are connected to a steel column 1 using bolts 3. The upper limit of the yield stress of the steel material used for the split tees 4 is defined to be not more than twice the lower limit thereof. Further, in order for the web 6 extending from the flange 5 of a split tee 4 in the axial direction of an H-shaped steel beam 7 to absorb earthquake energy by its plasticization, the cross-sectional area of the web 6 is reduced partially and the base end portion 6a of the web 6 is divided from the tip portion 6b which is connected to the flange 8 of the H-shaped steel beam 7.
