Review on response amplification damper for seismic resilient building structures

A state-of-the-art review is presented on the design and research based on response amplification dampers. In recent years, energy-dissipation vibration-reduction technology has been extensively employed for seismic resilience in building structures. Indeed, during minor-to-moderate earthquakes, the displacement or deformation of structures is relatively small, and they cannot fully exert their energy dissipation capacities. Therefore, amplifying the dynamic responses transmitted to the damper is important. Taking the field of shock absorption of building structures as the research object, this article describes the amplification mechanisms of response amplification dampers and elaborates on the device structures and working mechanisms of these dampers, indicating areas that require improvement. Concurrently, it introduces the seismic performance of building structures integrated with response-amplification dampers. To enable full determination of the energy dissipation capacities of dampers based on the seismic design method, this paper elaborates on methods of optimizing the parameters, quantity, and layouts of response amplification dampers. The latest research progress, shortcomings, and prospects are analyzed and summarized. The main purpose of this article is to provide a comprehensive overview of the shock absorption technology of building structures based on response amplification dampers, thus offering valuable reference information for further research and engineering applications in this field.
