Square steel tube concrete column-steel beam outer ring plate bolt connection joint
The invention discloses a square steel tube concrete column-steel beam outer ring plate bolt connection joint, and relates to the technical field of steel structure buildings. The square steel tube concrete column-steel beam outer ring plate bolt connection joint comprises a CFRP circular tube, a lower outer ring plate, two shear-resistant webs and two steel beams, wherein the CFRP circular tube is arranged in a square steel tube; the lower outer ring plate is parallel to an upper outer ring plate, and a lower positioning hole is formed in the position, corresponding to an upper positioning hole, of the lower outer ring plate; the two shear-resistant webs are connected with the upper outer ring plate and the lower outer ring plate; the two steel beams are H steel; and the two sides of the upper outer ring plate and the two sides of the lower outer ring plate are detachably connected with the two steel beams through connecting plates correspondingly. The square steel tube concrete column-steel beam outer ring plate bolt connection joint has good rotating capacity, ductility performance and anti-seismic property; when the joint is damaged, plastic hinges appear on the replaceable connecting plates firstly, and the upper outer ring plate, the lower outer ring plate and the steel tube do not generate serious plastic deformation; by replacing the connecting plates and bolts, the joint can be quickly repaired after an earthquake, and the repaired joint still has large energy dissipation capacity; and the joint repairing work is simple, and good economic benefits can be brought.
本发明公开了一种方钢管混凝土柱‑钢梁外环板螺栓连接节点,涉及钢结构建筑的技术领域，包括CFRP圆管，内置于方钢管内；下部外环板，与上部外环板平行，该下部外环板对应上定位孔的位置具有一下定位孔；两个抗剪腹板，连接上部外环板和下部外环板；两个钢梁，为H钢；其中，该上部外环板的两侧、下部外环板的两侧分别通过连接板与两个钢梁可拆卸连接；本发明节点具有良好的转动能力、延性性能、抗震性能；节点破坏时塑性铰率先出现在可替换的连接板上，确保上、下外环板及钢管不发生严重塑性变形；通过更换连接板及螺栓可使节点实现震后快速修复，修复后的节点仍有较大的能量耗散能力；节点修复工作简单，能够带来较好的经济效益。
