This paper presents the results of a study on a tuned liquid damper (TLD). The TLD uses air and liquid inside a U-shape tank as the mass of dynamic damper of a structure. By using the Lagrange method, the dynamic equation of motion for the fluid inside the structure with this U-shape tuned liquid damper is derived.
The natural frequency of the U-shape TLD is determined by finding the peak value of displacements of the liquid versus exciting accelerations. Vibration behaviours of the structure with and without U-shape TLD subjected to a simple harmonic excitation are examined in the time domain. Effects of mass ratio (mass of U-shape TLD/mass of structure) on vibration reduction are also studied.
