Due to the small interlayer displacement of the high-rise frame shear wall structure system under earthquake， the damper is difficult to play a good role in energy dissipation. Based on the deformation characteristics of core tube and peripheral frame structure， a high efficiency displacement amplification damper （SDA） is set at the position where the deformation of the core tube of the frame is concentrated， and a new energy dissipation structure with damping concentration system （NSD） is proposed. The energy dissipation mechanical properties of SDA are analyzed， and the damping force and energy dissipation theoretical formulas of the ordinary viscous damper （VD） and SDA are proposed. SDA with magnification of 3 times and VD are designed and fabricated，and the reciprocating loading test is carried out under the action of sine wave， the hysteretic energy dissipation curves of viscous dampers under different test conditions are analyzed. The theoretical curves are compared with the test curves to verify the correctness of the mechanical model. Comparing the energy dissipation effects of SDA and VD， it is concluded that under the same displacement， SDA has a fuller hysteresis curve and more significant energy dissipation than VD. Further， the seismic response of a NSD is analyzed， the results show that the NSD has good damping performance compared with the traditional structure.
