NONLINEAR SLOSHING ANALYSIS OF CIRCULAR TUNED LIQUID DAMPER BY USING BOUSSINESQ EQUATION

Abstract

A nonlinear Tuned Liquid Damper (TLD) 3D-model has been developed to investigate the nonlinear characteristics of circular TLD by using the Boussinesq equation. The numerical results were compared with the experimental data obtained from shaking table experiments. The validity of the proposed model was confirmed by the results of those comparisons. The nonlinear effects of wave in circular tank to TLD fluid dynamic force were also made clear to investigate the response curves, the phase curves and the visualized photographs of the free surface deformations from the numerical results.
