Abstract
This review article presents a detailed investigation into the seismic behavior of structures employing supplementary dampers or additional damping mechanisms over the past decade. The study covers a range of damping systems, including viscous, viscoelastic, and friction dampers, as well as tuned mass dampers and other approaches. A systematic analysis of more than 160 publications in the current literature is undertaken, providing a clear overview of structures equipped with supplementary damping devices and the challenges they face. The theoretical principles that underpin these technologies are examined, along with their practical applications and effectiveness in alleviating seismic effects. Additionally, the article highlights recent developments in the design of damping devices, the challenges related to their implementation, and prospective directions for future research. By synthesizing results from experimental studies, numerical simulations, and real-world applications, this review offers valuable insights for researchers and engineers involved in the design of earthquake-resistant structures.
