BUCKLING RESTRAINED BRACE AND BUILDING STRUCTURE THAT USES THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a buckling restrained brace, in which the conditions of its core material can be observed without dismantling it, and a building structure that uses the buckling restrained brace.SOLUTION: The buckling restrained brace in this invention comprises: a core material (1); at least a pair of stiffeners (21) arranged to sandwich the core material on two opposing faces of the core material without contacting with each other of the pair, allowing the both side-faces of the core material, which are not in contact with the stiffeners, to be seen from the outside; and fixing materials (3) that fix the pair of stiffeners. The fixing materials comprise: two protrusion parts (31) protruding from each of the pair of stiffeners in the direction which the stiffener's side-face faces to, and extending in parallel with the designated direction; and a plurality of connection parts (32) connecting the two protrusion parts with each other and being arranged to hide the side faces of the core material at certain intervals. With this arrangement, the side-faces of the core material can be seen from the outside.
