Zusammenfassung:	The utility model relates to the field of dampers, and discloses a double-order friction damper which comprises a center plate with a cross-shaped section, and a strip-shaped groove hole is formed in a horizontal plate of the center plate. The first connecting piece is in friction connection with one horizontal plate of the center plate; the first SMA spring is respectively connected with the first connecting piece and the central plate; the second connecting piece is in friction connection with the other horizontal plate of the central plate; and the second SMA spring is respectively connected with the second connecting piece and the central plate. A friction force difference exists between the friction force between the first connecting piece and one horizontal plate of the center plate and the friction force between the second connecting piece and the other horizontal plate of the center plate. After the center plate of the double-section friction damper generates relative displacement, the double-section
