Tandem type double-yield-point buckling restrained brace
The invention relates to a series-connection type double-yield-point buckling restrained brace which comprises an outer sleeve, an inner sleeve and an outer sleeve, the outer sleeve comprises a first outer sleeve and a second outer sleeve, the first outer sleeve and the second outer sleeve are connected in series, a plurality of anti-shear grooves are formed in the first outer sleeve in the circumferential direction, and the anti-shear grooves are evenly distributed in the longitudinal axis direction of the first outer sleeve; the yield inner core comprises a first yield section core material and a second yield section core material, the first yield section core material longitudinally penetrates through the first outer sleeve, and a plurality of shear keys are arranged on the first yield section core material; the second yield section core material longitudinally penetrates through the second outer sleeve and is fixed to the first yield section core material in a butt welding mode. And the confined concrete is filled between the first outer sleeve and the first yield section core material and between the second outer sleeve and the second yield section core material. The double-yield-point buckling restrained brace overcomes the defect that an existing buckling restrained brace device is insufficient in bearing capacity, the large-tonnage requirement can be met, the manufacturing cost is saved, and the application range of the double-yield-point buckling restrained brace is widened.
本发明涉及一种串联式双屈服点屈曲约束支撑，包括：外套筒，包括第一外套筒和第二外套筒，第一外套筒与第二外套筒串联连接，第一外套筒上沿周向开设有多个抗剪槽，多个抗剪槽沿第一外套筒的纵向轴线方向均匀布设；屈服内芯，包括第一屈服段芯材和第二屈服段芯材，第一屈服段芯材纵向贯穿于第一外套筒，并且第一屈服段芯材上设有多个抗剪键；第二屈服段芯材纵向贯穿于第二外套筒，并与第一屈服段芯材对接焊接固定；约束混凝土，填充于第一外套筒和第一屈服段芯材以及第二外套筒和所述第二屈服段芯材之间。本发明弥补了现有屈曲约束支撑装置承载能力的不足，可满足大吨位的要求并节约了造价，提升了双屈服点约束支撑的应用范围。
