Beam column joint with replaceable low-yield-point energy dissipation truss
The invention discloses a beam-column joint with a replaceable low-yield-point energy dissipation truss. The existing steel frame beam-column ductile joint does not consider the quick repairability after being damaged. The structure comprises a frame beam, a frame column and a lug plate located at the splicing position of the frame beam and the frame column. The upper flange and the lower flange of the frame beam are each provided with an energy dissipation truss. The energy dissipation truss is of a square hollow structure formed by two horizontal plates and two vertical plates, a plurality of fuse plates are obliquely arranged in the square hollow structure, and every two adjacent fuse plates and the horizontal plate form a triangle. The middle of the fuse plate is provided with a hole, the edge is weakened, and when the node is damaged, the energy consumption truss firstly enters plastic energy consumption and then is damaged, so that the purpose of protecting a permanent component is achieved; the energy dissipation truss is easy to disassemble and replace after an earthquake, and the possibility and convenience of repairing after the earthquake are achieved.
本发明公开了一种带可更换低屈服点耗能桁架的梁柱节点。现有钢框架梁－柱延性节点未考虑受损后的快速修复性。本发明包括框架梁和框架柱及位于架梁和框架柱拼接处的耳板，框架梁的上下翼缘分别设有耗能桁架；耗能桁架为两块水平板和两块垂直板构成的四方空心结构，四方空心结构内倾斜设有多个保险丝板，相邻两个保险丝板与水平板构成三角形。本发明保险丝板中间开孔，边缘处削弱处理，节点破坏时，耗能桁架先进入塑性耗能进而破坏，达到保护永久构件的目的；耗能桁架在震后易于拆卸更换，实现了震后可修复的可能性和便利性。
