ABSTRACT Seismic‐induced vibrations are harmful to high‐rise buildings. This study proposes the polymer damping multilayer anisotropic displacement amplified system (PDMADAS) as an effective method for mitigating these vibrations. The motion equations for single‐layer displacement amplified damper (SDAD), multilayer displacement amplified damper (MDAD), and multilayer anisotropic displacement amplified damper (MADAD) are derived. The multilayer anisotropic displacement amplified characteristics of MADAD are analyzed, and the control principle of the damping system is explained. Four damper prototypes are designed and manufactured, and their damping force and energy dissipation are evaluated through a series of mechanical performance tests. Additionally, the influence of PDMADAS on structural response control is investigated using the displacement amplification damper installed in the polymer damping system. Compared with VD, the amplification factors for the maximum damping force and energy consumption of MADAD are 12.09 and 10.64 times, respectively. The results show that combining the polymeric damping system with MADAD is more effective in reducing seismic response.
