Combined type joint damper
The invention provides a combined type joint damper, and belongs to the technical field of building structure vibration control. The damper is composed of a right-angle reinforcing mounting steel plate, a small four-branch arc reinforcing energy dissipation steel plate, a large four-branch arc reinforcing energy dissipation steel plate, a middle arc reinforcing energy dissipation steel plate, a straight reinforcing energy dissipation steel plate, springs and the like, wherein the small four-branch arc reinforcing energy dissipation steel plate, the large four-branch arc reinforcing energy dissipation steel plate, the middle arc reinforcing energy dissipation steel plate and the straight reinforcing energy dissipation steel plate are sequentially arranged at the inner corners of the right-angle reinforcing mounting steel plate from inside to outside; the first spring, the second spring and the third spring are sequentially arranged between the small four-branch arc reinforcing energy dissipation steel plate, the large four-branch arc reinforcing energy dissipation steel plate, the middle arc reinforcing energy dissipation steel plate and the straight reinforcing energy dissipation steel plate; and the two ends of the first spring, the two ends of the second spring and the two ends of the third spring face the middle point of the straight reinforcing energy dissipation steel plate, the middle point of the middle arc reinforcing energy dissipation steel plate, the middle point of the large four-branch arc reinforcing energy dissipation steel plate and the middle point of the small four-branch arc reinforcing energy dissipation steel plate correspondingly. The combined type joint damper is large in initial rigidity, large in material yield dispersion area and free of obvious stress concentration phenomenon, a series of medium-hard steel and soft steel have good coordination, and the energy dissipation effect is good.
一种组合式节点阻尼器，属于建筑结构振动控制技术领域，所述阻尼器由直角加强安装钢板、小四分弧加强耗能钢板、大四分弧加强耗能钢板、中间弧加强耗能钢板、直加强耗能钢板、弹簧等组成，所述直角加强安装钢板内角处从内向外依次设有小四分弧加强耗能钢板、大四分弧加强耗能钢板、中间弧加强耗能钢板、直加强耗能钢板，他们之间依次设置第一弹簧、第二弹簧、第三弹簧，所述第一弹簧、第二弹簧、第三弹簧的两端分别对着直加强耗能钢板、中间弧加强耗能钢板、大四分弧加强耗能钢板、小四分弧加强耗能钢板的中点。本发明组合式节点阻尼器初始刚度较大，材料屈服分散面积大，无明显应力集中现象，一系列中硬钢与软钢具有较好的协调性，耗能效果好。
