In order to evaluate the control performance of the tuned liquid column damper in suppressing pitching vibration of structures, an optimal parametric study of the damper is carried out for an undamped structure. The structure is assumed to be subjected to harmonic excitation in the analysis. The opt

A Lagrangian displacement-based #uid element has been developed to model large amplitude free surface motion of nearly incompressible viscous #uids in a tank of rectangular cross-section under dynamic excitation for tuned liquid damper applications. The penalty method is employed to enforce the near
The Tuned Liquid Damper (TLD) is modelled numerically as an equivalent tuned mass damper with non-linear sti!ness and damping. These parameters are derived from extensive experimental results described in References 1 and 2. This Non-linear Sti!ness and Damping (NSD) model captures the behaviour of
Numerical simulations of a single-degree-of-freedom (SDOF) structure, rigidly supporting a tuned liquid damper (TLD) and subjected to both real and arti"cially generated earthquake ground motions, show that a properly designed TLD can signi"cantly reduce the structure's response to these motions. Th
