Asian Journal of Civil Engineering, 2 (2001), 1; 1 - 10.

Results from experimental studies of time-harmonic excited structures with installed Tuned Liquid Column Dampers (TLCDs) are presented. The experimental model consists of a small-scale plane one-storey shear frame, made of aluminum, with a TLCD mounted to its rigid beam. A TLCD is a U-shaped tube of constant cross-section, and it is filled with liquid (pure water). The natural frequencies of the shear frame and the TLCD are tuned by modifying the length of the liquid. The effectiveness of TLCDs in the reduction of the dynamic response of structures is demonstrated by means of frequency sweep response functions. The optimal tuning ratio and the optimal geometry of the TLCD container are determined. TLCDs of different shape are studied and subsequently evaluated.
