Torsional Vibration Control of a Structure using Fluid Viscous Dampers
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Damping plays a major role in design of structures resistant to earthquakes. The damping reduces the effective of the structure when they are assigned to lateral loads by energy dissipation. The number of dampers is available and in use today.
