A Numerical Investigation of the Impact of Non-linear Viscous Damping on Structural Response to Seismic Excitation

Ensuring building safety and seismic protection are vital considerations for civil engineers when designing structures. Seismic dampers, a relatively new technology in buildings, can significantly mitigate the risk of damage and destruction during an earthquake or other seismic events. Dampers have emerged as crucial control mechanisms in buildings to mitigate vibrations induced by lateral loads, notably seismic events. Different type of dampers, including viscous, tuned mass, friction, and hybrid dampers, have garnered significant attention for their effectiveness in reducing the adverse effects of earthquakes. This study delves into the role of dampers in structural control and their utilization to counteract seismic forces. Through numerical simulations and analysis, the study examines the effectiveness of various damper types in improving structural resilience and minimizing seismic-induced vibrations. Specifically, the research focuses on the role of nonlinear viscous damping in affecting the performance of multi-degree-of-freedom (MDOF) structures. By exploring the diverse applications of dampers, particularly nonlinear viscous damping. The study aims to further the development of earthquake resistant building design and construction practices.
