A control system can significantly improve the strength of structures to mitigate vibrations or their effects on the structure, keeping them within limits safe and meeting safety standards. One of the ways to promote this dampening of oscillations on the structure to be protected is the tuned liquid column damper (TLCD). This system promotes the damping of the structure’s oscillations through the oscillation of the liquid in a U-shaped reservoir, in which the liquid moves in opposition to the structure’s movement. The damping force is associated with the energy dissipation when the liquid passes through the orifice in its horizontal part. We take this non-conservative force with a linear dependence on the velocity. With this simplified model, we obtained analytical expressions for the description of the damping that is within the expected.
