JOINT STRUCTURE OF BUCKLING RESTRAINING BRACE
PROBLEM TO BE SOLVED: To provide a joint structure of a buckling restraining brace, which can achieve restrictions on the length and weight of a member during transportation, bring about proper detailing and cost reduction, and facilitate the securement of the plasticization length of the whole brace, even when a buckling restraining brace is used for seismic rehabilitation and the like.SOLUTION: Two buckling restraining brace split bodies 1A, in which a flat plate-like core material 2 is pinched by a restraining material 3, are joined in series to be turned into one buckling restraining brace. An end of the core material 2 on the mutual joint side of both the buckling restraining brace split bodies 1A serves as a flat plate-like core material joint-side protrusion 2c that is protruded with respect to the restraining material 3. The core material joint-side protrusion 2c comprises a restraining width part 2ca equal in width to a part, pinched by the restraining material 3, of the core material 2, and a pair of extended parts 2cb extended to both sides from the restraining width part 2ca. The restraining width part 2ca and the extended part 2cb are divided from each other by a slit 2cc except for a part. Both the core material joint-side protrusions 2c are pinched between two splice plates 11, and joined by a bolt 12 via the extended part 2cb.
【課題】 耐震改修等に座屈拘束ブレースを用いる時も、運搬時の部材長さや重量の制約を達成でき、かつ納まり良くコストも低減でき、さらにブレース全体の塑性化長さを確保し易い座屈拘束ブレースの接合構造を提供する。【解決手段】 平板状の芯材２を拘束材３で挟み付けた２本の座屈拘束ブレース分割体１Ａを直列に接合して１本の座屈拘束ブレースとする。両座屈拘束ブレース分割体１Ａの互いの接合側の芯材２の端部を、拘束材３よりも突出させた平板状の芯材接合側突出部２ｃとする。芯材接合側突出部２ｃは、芯材２の拘束材３で挟まれた部分と同じ幅の拘束幅部２ｃａと、拘束幅部２ｃａから両側へ広げた一対の広がり部２ｃｂとでなり、拘束幅部２ｃａと広がり部２ｃｂとは一部を除いてスリット２ｃｃで互いに分断されている。両芯材接合側突出部２ｃは２枚の添え板１１で挟み込んで前記広がり部２ｃｂでボルト１２により接合する。【選択図】 図１
