Self-resetting friction energy dissipation type fabricated beam column node
The invention relates to a self-resetting friction energy dissipation type fabricated beam column connecting nod. The connecting nod comprises an H-shaped steel column, cantilever section steel beamsand middle section steel beams; the side ends of the cantilever section steel beams are connected to the column flange of the H-shaped steel column, the other side ends of the cantilever section steelbeams are connected with a first arc-shaped plate, the side ends of the middle section steel beams are connected with a second arc-shaped plate, the second arc-shaped plate is connected with the first arc-shaped plate through a high-strength bolt, and bolt holes in the second arc-shaped plate are oblong bolt holes; and steel beam stiffening ribs are arranged on webs of the cantilever section steel beams and the middle section steel beams, rib plate reinforcing pieces are arranged on the steel beam stiffening ribs, and steel beam stiffening ribs of the cantilever section steel beams are connected with steel beam stiffening ribs of the middle section steel beams through prestressed members. According to the connecting nod, the deformation and damage generated by an earthquake on the node can be weakened by utilizing the friction energy consumption of the arc-shaped plates, the relative stability of the main body structure is maintained, and self-repairing or artificial repairing after the earthquake is also facilitated.
一种自复位摩擦耗能型装配式梁柱连接节点，包括H型钢柱、悬臂段钢梁和中间段钢梁，所述悬臂段钢梁的侧端连接在H型钢柱的柱翼缘上，其另一侧端连接有第一弧形板，所述中间段钢梁的侧端连接有第二弧形板，所述第二弧形板与第一弧形板通过高强螺栓相连接，所述第二弧形板上的螺栓孔为长圆螺栓孔；所述悬臂段钢梁与中间段钢梁的腹板上均设置有钢梁加劲肋，所述钢梁加劲肋上设置有肋板加强件，所述悬臂段钢梁的钢梁加劲肋通过预应力构件与中间段钢梁的钢梁加劲肋相连接。本发明利用弧形板的摩擦耗能来削弱地震对节点产生的变形和损伤，维持主体结构的相对稳定，也有利于震后自修复或人工修复。
