To　meet　the　engineering　demand　for　vibration　control　of　a　super-tall　integral　jacking　platform　moulding　system,　a　tuned　liquid　damper　(TLD)　is　used　for　the　tuned　control　device　of　the　construction　steel　platform.　An　experimental　method　for　isolating　the　substructure　is　proposed,　and　the　effectiveness　of　the　TLD　for　vibration　damping　control　of　the　steel　platform　is　verified　by　shaking　table　tests.　The　test　results　show　that　the　dynamic　response　of　the　construction　steel　platform　and　the　main　body　of　the　structure　under　earthquake　can　be　suppressed　simultaneously　by　controlling　the　mass　ratio　of　TLD　to　the　construction　platform　within　5%,　and　the　displacement　damping　effect　is　good.
