[en] This paper discusses methods for deriving equivalent damping for vortex-induced vibrations. Here, equivalence is defined as the structural damping ratio that would produce the same maximum displacement as a structure equipped with a Tuned Mass Damper. Given that the wind loads resulting from VIV are neither perfectly narrowband nor wide band, the equivalence presented in this paper is unique. Based on Tamura’s 2-D wake oscillator model, the three governing differential equations of the damped wake oscillator are analyzed and illustrated numerically.
