Characterization of damping forces in a vibrating structure has long been an active area of research in structural dynamics. The most common approach is to use &&viscous damping'' where the instantaneous generalized velocities are the only relevant state variables that a!ect damping forces. However,

A non-linearly damped single-degree-of-freedom (s.d.o.f.) system under broadband random excitation is considered. A procedure for in-service identi"cation of the damping characteristic from measured stationary response is described. The procedure is based on the stochastic averaging method. The expl

In a companion paper (see pp. 43} 61 of this issue), it was shown that when a system is non-viscously damped, an identi"ed equivalent viscous damping model does not accurately represent the damping behaviour. This demands new methodologies to identify non-viscous damping models. This paper takes a "
