Zusammenfassung: | To provide a buckling restraining brace that can be easily fabricated with minimal environmental impact.SOLUTION: A buckling restraining brace 5 attached to a frame structure, comprises: a cross-shaped core material 52 whose both ends are fixed to the frame structure; an outer shell 51 formed by square steel tubes surrounding the longitudinal perimeter of the core material; and a stiffening steel tube 53 formed by circular steel tubes arranged between all internal corners of the core material and an inner surface of the outer shell. Further, at the ends of the core material, widened ends 521 are provided so as to be switchable to pass through or not to pass through depending on an orientation of the outer shell with respect to an inner space of the outer shell.SELECTED DRAWING: Figure 1
【課題】環境に与える負荷を抑えて簡単に製作することが可能になる座屈拘束ブレースを提供する。【解決手段】架構構造に取り付けられる座屈拘束ブレース5である。そして、架構構造に両端部が固定される断面十字状の芯材52と、芯材の長手方向の周囲を取り囲む角形鋼管によって形成される外殻部51と、芯材のすべての入隅部と外殻部の内周面との間に配置される円形鋼管によって形成される補剛鋼管53とを備えている。また、芯材の両端には、外殻部の内空に対する向きによって通過の可否の切り替えが可能な拡幅端部521が設けられている。【選択図】図1 |
