A time-independent finite difference method was used to solve for a fully nonlinear sloshing fluid in a tank mounted on a structure. The interaction between the sloshing fluid and the dynamic response of the structure was investigated. The dynamic response of the structure was calculated using the fourth-order Runge-Kutta method, and the numerical model was extensively validated through comprehensive data comparisons. The tank was tuned to an appropriate depth to length ratio and was used as a tuned liquid damper. Several cases, including large and small structures, were studied. In addition, a vibration control analysis of the tank-structure system in a real earthquake scenario is described in this paper. Vibration control was tested in terms of reduction in the dynamic response of the structure and reduction in the maximum energy development in the tank-structure system during excitation. The response of the tank-structure system was sensitive to the excitation frequency and water depth in the fluid tank.
