摘要： PROBLEM TO BE SOLVED: To provide a beam-column connecting structure which ensures yield only of split tees thereof at a predetermined set value without destroying the structure other than the split tees even in a large earthquake or the like, whereby only the split tees incapable of further reuse is exchangeable, and to provide a steel column for use in the structure. SOLUTION: The pair of upper and lower split tees 4 are each formed by bolting 3 a flange 5 to the steel column 1, and a wide-flange beam 7 is built into the split tees 4 such that ends 8a of both upper and lower flanges 8 of the wide-flange beam 7 are attached to webs 6 of the respective split tees 4, followed by bolting 9 the flanges 8 to the webs 6, respectively. A yield point control value of a steel product at the split tee 4 is set such that an upper limit value of a control point is two times or less a lower limit value of the control point. Further, a sectional area of the web 6 is partially reduced so that the web 6 extending from the flange 5 in an axial direction of the wide- flange beam 7, absorbs earthquake energy due to plasticisation thereof. Therefore, a base-side end 6a of the web 6 is partitioned from a distal end 6b having the flange 8 of the wide-flange beam 7 connected thereto.

摘要： PROBLEM TO BE SOLVED: To prevent plasticization of a bracket base by increasing the width and/or thickness of flange of the bracket base and absorb an external force energy by forming a plastic hinge at the vicinity thereof. SOLUTION: The base end of a steel bracket 3 with an H-shaped section is welded and connected to the side face of a steel frame column 1 with a box-shaped section and a beam 2 with an H-shaped section is bolted or welded to the front end to constitute a structural frame. In this case, the flange width and/or thickness of the base end of the bracket is increased to make the ratio of the section modulus of the welded part B of the end to the plastic section modulus of the plasticization part A larger than the ratio of the maximum yield stress of an applied steel plate and the minimum yield stress. In this way, when a plastic hinge is formed in the plasticization part A of the bracket 3 by a bending load resulting from an earthquake or the like, the stress of the welded part B becomes smaller than the minimum yield stress of the steel member to prevent the fracture of the welded part B of the end and secure the deforming performance by the plastic hinge and absorb an external force energy.

摘要： PROBLEM TO BE SOLVED: To improve rigidity and yield strength without causing eccentricity by inserting multiple steel central axial force members into at least one side of a buckling constraining concrete member integrated into a cross shape, inserting one or more steel central axial force members into the other side, and providing sticking preventing films between the steel central axial force member surfaces and the concrete member. SOLUTION: Steel central axial force members 2 are inserted into steel pipes 5 combined into a cross shape, steel reinforcing rib plates 6 are fixed to both end sections of the central axial force members 2, and sticking preventing films 3 are formed at the inner portions of the steel pipes 5 at the central members 2 and the rib plates 6. Concrete 8 is filled into the steel pipes 5 to form a buckling constraining concrete member 1. The steel central axial force members 2 in the steel pipes 5 are formed with one band plate in one direction and two band plates in the other direction, and they cross noneccentrically to each other at a central intersection, thereby the buckling constraining concrete member 1 serving as two brace members can be arranged into an X-shape without causing eccentricity in a limited area, and its rigidity and yield strength can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a beam joint structure capable of lengthening a plasticized part in a splice plate to make small the strain in this part, preventing the lowering of fatigue characteristic also to a quick deformation in the case of earthquake without varying mechanical characteristics of the splice plate without being welded to the splice plate and preventing the beam as a main structural member from being plasticized to facilitate the repair in the case of earthquake.
SOLUTION: The beam joint structure is so constituted that a beam flange 1 is connected to a flange 7 on a column side with a fixed means through the splice plate 9 having the plasticized part in the intermediate section. A separate buckling restraining member 13 restraining the buckling of the plasticized part 11 is provided to the plasticized part 11 of the splice plate 9 in an unadhering state.
