Summary: | Water storage tanks are critical infrastructure that requires maintenance to ensure they function efficiently. Earthquake‐induced sloshing and hydrodynamic pressures can cause significant stress and damage in liquid storage tanks. Various methods have been used to reduce sloshing effects in these structures. This study proposes a new method to reduce the sloshing of partially filled rectangular water storage tanks during earthquake ground motions. A pendulum steel wall system is used to create a sloshing control system. The hydrodynamic equation of motion for these systems is derived analytically using the velocity potential function. Eight different ground motions, categorized as near‐fault and far‐fault, were chosen to analyze the dynamic responses of liquid storage tanks equipped with this system. The study also examines the effect of different wall connection placements relative to the water’s free surface on the system’s performance. The results, in terms of wave elevation, base shear, and base moment, show that the submerged pendulum wall system is more successful in reducing base shear and base moment levels than wave elevation. The study also recommends the optimal connection location in the tanks. |
