摘要： PROBLEM TO BE SOLVED: To increase energy absorbing capacity and prevent buckling by oppositely arranging channel steels and visco-elastic body sheets surrounding a first core material to be laminatedly stuck. and fixing the end parts of the channel steel to a second core material arranged through an expansible gap.
SOLUTION: This visco-elastic brace 2 is formed so that first visco-elastic body sheets 9 and first channel steels 6 are alternately laminatedly stuck on the sides of a first core material 3 of H-shaped section, and they are oppositely arranged so as to surround it. The end parts of first channel steels 6 are fixed to a second core material 4 of H-shaped section through first channel steel fixing materials 13. The sectional form of the first core material 3 and the second core material 4 can be formed into a square steel pipe or a circular steel pipe. An expansible gap 30 is interposed between the first core material 3 and the second core material 4. Hereby, the radium of gyration of the core material can be enlarged and the visco-elastic sheet can be prevented from peeling off. Consequently, buckling at compression can be prevented, deformation and shearing force in the horizontal direction of a multistory building and the like accompanying horizontal vibration are lightened, and the vibration can be quickly damped.

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： PURPOSE:To use a steel bar safely as an exposed tension member of the tension structure by providing a function for allowing the rotation of a steel bar. CONSTITUTION:A steel bar 5 is inserted from a small diameter hole 4 in to a large diameter hole 2 of a socket 1, and a nut 7 is screwed with a screw bar part 6 of the end of the steel bar 5. A screw thread part 11 of the peripheral surface is screwed with a fitting hole 10 of a fixation object 9 side to fit the socket 1 to the fixation object 9. The socket 1 is screwed into the direction for coming close to the inner bottom surface of the fitting hole 10, and a seat part 3 of the socket 1 is made to abut on a shoulder part 8 of the nut 7 to fix the steel bar 5 between two fixation objects 9 under the tensile condition. When the fixation object 9 is displaced by the wind pressure or the earthquake, the steel bar 5 is rotated within a certain range, making the shoulder part 8 of the nut 7 slide to abut on the seat part 3 of the socket 1, to eliminate the bending stress to be applied to the steel bar 5. The steel bar 5 can be thereby used safely as an exposed tension member of the tension structure.
