Triple circular steel pipe buckling restrained brace
The invention discloses a triple circular steel pipe buckling restrained brace, and relates to buckling restrained braces. The triple circular steel pipe buckling restrained brace solves the problemsexisting in an existing all-steel restrained component that an energy dissipation inner core is directly connected with a joint so that full-range restraint cannot be carried out on a brace inner core, an energy dissipation circular pipe is not subjected to variable cross-section treatment to lead to plastic deformation of a brace being mainly concentrated at the two ends of the circular pipe under the action of an earthquake, and torsional deformation of the energy dissipation circular pipe is beyond restraint. The triple circular steel pipe buckling restrained brace consists of an inner restraint pipe, an energy dissipation pipe, an outer restraint pipe, an inserting piece, a cushion ring and a torsion limiting rod; and the inner restraint pipe, the energy dissipation pipe and the outerrestraint pipe are sequentially arranged together from inside to outside in a sleeved mode. The triple circular steel pipe buckling restrained brace has advantages that: 1, it is guaranteed that the energy dissipation inner core is restrained in a full range, and the stability of the brace is improved; 2, it is ensured that the plastic deformation is mainly concentrated in a grooving area; and 3,the fatigue performance is improved.
一种三重圆钢管屈曲约束支撑，它涉及一种屈曲约束支撑。本发明的目的是要解决现有全钢约束部件存在耗能内芯直接与节点相连，导致无法对支撑内芯进行全范围约束，未对耗能圆管进行变截面处理，导致支撑在地震作用下塑性变形主要集中在圆管两端，及不能抑制耗能圆管的扭转变形的问题；三重圆钢管屈曲约束支撑由内约束管、耗能管、外约束管、插接件、垫环和扭转限位杆组成；所述内约束管、耗能管和外约束管由内至外依次套装在一起；优点：1、保证耗能内芯被全范围约束，提高支撑的稳定性；2、保证塑性变形主要集中在开槽区域。3、提高的疲劳性能。本发明主要用于制备三重圆钢管屈曲约束支撑。
