Abstract: A friction energy dissipation column for bi-directional deformation cooperative and multi-stage working, includes two cantilever part I-shaped steel columns, a middle part I-shaped steel column, wherein the middle part I-shaped steel column is located between the two cantilever part I-shaped steel columns, and the middle part I-shaped steel column is detachably connected to the two cantilever part I-shaped steel columns via a pin shaft connector and a friction energy dissipation assembly. An upper end and a lower end web of the friction energy dissipation column are connected to the frame beam via a connecting plate, and the flanges on both sides are provided with haunched supports.
