Tall structures are built in urban areas to accommodate large number of populations because of land constraint issue. These types of structures are susceptible to strong ground motions of varying frequency contents. Many researchers have developed various mechanisms to minimize the vibration of tall and slender structures subjected to strong ground motions. Tuned liquid damper is one of the passive damping devices attached to the structure to reduce the vibration. Various numerical methods have been developed to analyze the fluid flow behavior inside the tuned liquid damper. The mesh-based methods fail to capture the complex nonlinear fluid flow behaviour inside the damper and the related phenomena. The present study proposes a particle-based method for the analysis of fluid flow behaviour inside the tuned liquid damper. The proposed method is validated with the results of earlier established studies. Results showed that the moving particle semi-implicit method is one of the robust numerical methods used now-a-days to capture the wave breaking phenomenon inside the tank, wave impact on the side walls of the tank and free board in a consistent manner.
