Viscous Damper, Damper Subsystem Stiffness, and Damper Placement: State-of-Art Review
To fulfil the growing demand for energy dissipation prior to yielding structural elements to inelastic deformation during seismic excitations, engineers pay particular attention to increasing stiffness and damping characteristics by applying seismic design strategies and inserting passive energy dissipation systems, respectively. Supplemental dampers, such as viscous dampers, are proving to be more effective than simply increasing the stiffness of the structural member when it comes to improving seismic performance in newly constructed structures or introducing a retrofit for inadequately designed structures in moderate and high seismic zones. Even though the characteristics of supplemental dampers, structures, and earthquake ground motion need to be well studied, it is worthwhile to investigate the efficacy of brace-damper stiffness, configuration, and damper placement on response reduction, enhancement of seismic performance, and mitigating weakly constructed structures. This review focuses on giving in-depth information about how viscous dampers work and how the configuration of brace dampers and placement of viscous dampers enhance the performance of structures. However, further investigations are required to conduct analytical research on the effectiveness of the stiffness of the brace damper in enhancing seismic performance and reducing structural response. For designing resilient new structures or retrofitting existing ones, knowing how the stiffness of the damper subsystem interacts with the parameters of the viscous damper is essential.
