Experimental study demonstrates improved vibration control in steel towers using tuned liquid dampers, suggesting practical applications for structural engineering.
This study presents a full‐scale experimental study on a Tuned Liquid Damper (TLD) for vibration control of slender steel towers. A 25 m prototype tower was subjected to ambient excitation, harmonic forced vibration, and free‐decay tests. The results show up to a sixfold increase in structural damping compared to the uncontrolled configuration, with an effective logarithmic decrement of 4% in the optimal case. Empirical data capture the nonlinear behavior and support the validity of established TLD design models, with close agreement between analytical predictions and measurements. These findings demonstrate the technical feasibility of circular TLDs as an effective solution to reduce wind‐induced vibrations in slender structures.
