Tuned liquid damper (TLD) is a common type of passive damper system in high-rise buildingsl. However, the damping of a pure water TLD system is relatively small. Adding internal baffles can significantly increase its damping ratio, thereby improving its vibration control efficiency. In this study, a numerical simulation of liquid sloshing in a TLD system with vertical baffles is conducted using the open-source computational fluid dynamics(CFD) software OpenFOAM. The wind-induced response of the benchmark building for the third-generation wind-induced vibration control study is investigated using the computational structure dynamics (CSD) method. On this basis, the CFD/CSD coupling numerical simulation is conducted to evaluate the control efficiency on wind-induced vibration control of a tall building and a TLD system with built-in vertical baffles. The CFD/CSD coupling numerical simulation results show that the TLD system with three vertical baffles has a significant control effect on the wind-induced response of the benchmark building under dynamic wind loading with different return periods. The comparison with real-time hybrid test results also confirms that the proposed numerical algorithm in this paper has sufficient accuracy in estimating the wind-induced control efficiency.
