In two recent papers (Adhikari and Woodhouse 2001 Journal of Sound and <ibration 243, 43}61; 63}88), methods were proposed to identify viscous and non-viscous damping models for vibrating systems using measured complex frequencies and mode shapes. In many cases, the identi"ed damping matrix becomes

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,

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 "

This work represents an extension and experimental verification of earlier work proposed for modal identification of distributed structures in the time domain. The Temporal Correlation Method has been shown to be a constrained version of the Eigensystem Realization Algorithm. Furthermore, in this me
