✦ Synopsis

This paper presents a numerical study for structural control using a tuned liquid damper (TLD), which consists of solid tank ®lled with liquid. In order to determine the complete behavior, it is necessary to investigate the phenomenon coupling with structure and ¯uid. In the ¯uid analysis, the Navier±Stokes equation is used in the form of the arbitrary Lagrangian±Eulerian (ALE) formulation. For the discretization of the incompressible Navier± Stokes equation, the improved-balancing-tensor-diusivity method and the fractional-step method are used. For computational stability, smoothing on the free surface is carried out. In the structural analysis, the Newmark's b method is used for the time discretization. It is shown that the method presented in this paper is suitable for the analysis and the tuned liquid damper is ecient in reducing the oscillation.

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.
