In this study, the vibration control performance of Tuned Liquid Damper(TLD) with nonlinear properties is investigate by a with shaking table test according to large excitation. Until recently, TLDs has been investigated by behavior of liquid using equivalent TMD analogy and liner wave theory. The properties of TLDs assumed immutable but became generally known as a matter of fact TLDs behavior has a nonlinear properties that change the TLDs characteristics according to excitation. It was measured base shear and wave height in water tank at 0.01g to 0.06g as 0.01g intercals and tuned 0.6Hz, 0.8Hz. The result of shaking table test showed trend decreased amplification ratio of base shear and wave height as more increased peak accelearation of vibration, what is more jump frequency that dependent excitation dimension.
