In this paper, the experimental investigation to systematically calibrate the basic properties of tuned liquid column damper (TLCD) is conducted. Under harmonic excitation, the exact solution of the liquid response in TLCD is firstly derived and it is used in the experimental calibration. Both the free vibration and harmonic forced vibration tests via shake table are performed to obtain the experimental results for calibration. Consequently, an empirical formula to predict head loss coefficients for TLCD is constructed and proposed as a quick reference for designers. The experimental investigation also confirms the fact that the size of liquid mass and the difference of the ratio of horizontal column length versus total column length have no effect on the natural frequency and head loss as well.
