Detachable connecting rod connection and energy consumption friction type beam-column joint
The invention discloses a detachable connecting rod connection and energy consumption friction type beam-column joint, and relates to the technical field of steel-concrete combined structures. The detachable connecting rod connection and energy consumption friction type beam-column joint comprises a stand column and a cross beam; the end part of the cross beam is connected with one side of the stand column; the stand column and the cross beam are connected through a connecting assembly; and one end of the connecting assembly is connected with the stand column, and the other end of the connecting assembly is slidably connected with the cross beam. When an earthquake occurs, a hollow steel pipe connecting rod can effectively transmit shearing force and bending moment of the beam-column joint, disassembling and replacing are easy, a steel beam and a connecting piece are in lossless connection, a bolt end plate at the connecting position can slide, and therefore ductility and energy dissipation capacity of the joint are improved. In addition, the wall thickness and the diameter of the hollow steel pipe can be changed according to stress requirements, damage control design is achieved, and the damaged hollow steel pipe is easy to replace. The structure function of the beam-column joint can be rapidly recovered, and therefore the combined-structure detachable connecting rod connection and energy consumption friction type beam-column joint has the advantages of being detachable, capable of achieving damage control design, high in ductility and recoverable in function after the earthquake.
本发明公开一种可拆卸连杆连接耗能摩擦型梁柱节点，涉及钢混组合结构技术领域，包括立柱和横梁；横梁的端部与立柱的一侧相连接；立柱与横梁之间通过连接组件相连接；连接组件一端与立柱相连接，连接组件另一端与横梁可滑动连接。在发生地震时，空心钢管连杆既能有效传递梁柱节点的剪力和弯矩，又易于拆卸更换，钢梁与连接件为无损连接，连接处螺栓端板能够产生滑移，提高节点的延性、耗能能力。另外，可根据受力需求改变空心钢管的壁厚与直径，实现损伤控制设计，损伤后的空心钢管易于更换。可快速恢复梁柱节点的结构功能，因此，本发明的组合结构可拆卸连杆耗能摩擦型梁柱节点，具有可拆卸性、损伤控制设计、高延性、震后功能可恢复的优点。
