Abstract To develop function separate dampers with large deformation and high energy absorption, the frame fixture was applied to design lowyieldstrength steel shear panel damper (LYSPD). The effects of link strength and length of frame fixture on the performance of lowyieldstrength steel shear panel (LYSP) were investigated. The static hysteretic incremental experiments were used to determine the stress concentration factor of dampers. By image processing techniques, the shear strain of shear panel was employed to analyze the failure process of LYSP. The experimental results show that the frame fixture with enough link strength and large link length can effectively reduce the strain concentration factor and markedly improve the deformation capacity and energy absorption of the damper.
