The invention discloses an assembly type replaceable steel frame combination node and an assembly method. An H-shaped steel column, a cantilever beam section, a middle beam section, a concrete plate and a prefabricated concrete plate are adopted, and one end of the cantilever beam section is fixedly connected with a column flange of the H-shaped steel column; an upper flange and a lower flange at the other end of the cantilever beam section are fixedly connected with an upper flange and a lower flange at one end of the middle beam section through buckling constraint cover plates, the concrete slab is poured at the upper ends of the cantilever beam section and the middle beam section and connected with the upper end of the middle beam section through shear-resistant studs, and a web of the cantilever beam section and a web of the middle beam section are spliced through web splicing plates. Under the action of an earthquake, an inner core component formed by the buckling restrained cover plates yields before a main body steel frame, the inner core component of the flange connecting plate is damaged in a concentrated mode through the high ductility and the high energy dissipation capacity of low-yield-point steel, and the purpose of protecting a main body structure is achieved; and quick recovery of the structure function is realized by replacing the connecting part after an earthquake.
本发明公开了一种装配式可更换钢框架组合节点及装配方法，采用H型钢柱、悬臂梁段、中间梁段、混凝土板和预制混凝土板，悬臂梁段一端与H型钢柱的柱翼缘固定连接，悬臂梁段另一端的上、下翼缘与中间梁段一端的上、下翼缘通过屈曲约束盖板固定连接，混凝土板浇筑于悬臂梁段及中间梁段的上端，与中间梁段上端通过抗剪栓钉连接，悬臂梁段腹板和中间梁段的腹板通过腹板拼接板进行拼接，形成配置可更换屈曲约束盖板的装配式钢框架组合节点，在地震作用下，屈曲约束盖板形成的内核构件先于主体钢框架发生屈服，利用低屈服点钢的高延性和高耗能能力集中损伤于翼缘连接板内核构件，达到保护主体结构的目的，震后通过更换连接部分实现结构功能的快速恢复。
