The constructional detail and theoretical calculation of a kind of axial compression-tension metallic damper are introduced. The yield displacement, yield load and yield stiffness of the axial compression-tension metallic damper were obtained through the quasi-static test, and its energy dissipation capacity is analysed. The application of the damper used in External Prestressing Self-centering Frame (EPSCF) is researched. The results indicate that (1) the axial tension-compression metallic damper dissipates energy through the deformation of its web plates, and the damages occurred on the adjacent components can be avoided; (2) the installation type of this metallic damper is the same as the viscous damper, it can be conveniently installed and easily replaced; (3) the axial compression-tension metallic damper has the advantages of promoting additional stiffness, controlling drifts and dissipating seismic energy.
