The Tuned Liquid Damper (TLD) is modelled numerically as an equivalent tuned mass damper with non‐linear stiffness and damping. These parameters are derived from extensive experimental results described in References 1 and 2. This Non‐linear Stiffness and Damping (NSD) model captures the behaviour of the TLD system adequately under a variety of loading conditions. In particular, the NSD model incorporates the stiffness hardening property of the TLD under large amplitude excitation. Copyright © 1999 John Wiley & Sons, Ltd.
