This paper presents the results of experimental investigations on the response control performance of tuned liquid damper(TLD). Steel frame building model is used for the experiments. Shaking table is controled by velocity consol. Experimental variables are mass ratios(u=mass of TLD/mass of structure), shape ratio(depth of water/ length of TLD), number of nets(N) and tuned frequency ratio(fl/fs). Results show that the greater the mass ratio is, the more good the control performance is. So, it can be concluded that TLD is able to be used for the remodeling of existing buildings that are not designed to resist earthquake
