Perforated triple steel pipe buckling restrained brace
The invention provides a trepanned triple steel tube buckling restrained brace which comprises a core steel tube, an outer restrained steel tube and an inner restrained steel tube, a plurality of holes are formed in the core steel tube in the length direction, the inner restrained steel tube is arranged on the inner side of the core steel tube, and the outer restrained steel tube is arranged on the outer side of the core steel tube. A triple-pipe type structure is adopted, the advantage that the inertia moment of the hollow steel pipe is large is fully utilized, the restraining capacity of the restraining steel pipe on the core steel pipe is effectively improved, and the multiple holes are formed in the core steel pipe to concentrate plastic deformation generated by the buckling restraining support under the axial tension and compression effect on the hole opening section. Fixed-point yield and multi-point simultaneous yield energy consumption can be achieved at the same time, the performance of steel is brought into full play, high energy consumption efficiency is achieved, and the steel consumption and cost of the buckling restrained brace are reduced.
本发明提供了一种开孔三重钢管屈曲约束支撑,包括核心钢管、外约束钢管和内约束钢管,所述核心钢管在长度方向上开设有多个孔,所述内约束钢管设置在所述核心钢管的内侧,所述外约束钢管设置在所述核心钢管的外侧。本发明采用三重管式构造,充分利用空心钢管惯性矩大的优点,有效提高约束钢管对核心钢管的约束能力,核心钢管上设有多个孔将屈曲约束支撑在轴向拉压作用下产生的塑性变形集中于开孔段,实现定点屈服的同时又可以实现多点同时屈服耗能,充分发挥钢材的性能,具有较高的耗能效率,降低屈曲约束支撑用钢量与成本。
