Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down; see viscous damping) in mechanical systems, resistance in electronic oscillators, and absorption and scattering of light in optical oscillators. Da… WebApr 20, 2024 · For steel and concrete offshore structures, the damping ratio varies from 0.2 to 0.5% and 0.5 to 1.5% of the critical [ 20 ].
