Taking　the　advantages　of　tuned　mass　damper　(TMD)　and　tuned　liquid　column　dampers　(TLCD)　in　civil　engineering　vibration　control,　a　double　tuned　liquid　column　damper　(DTLCD)　was　presented　considering　the　cost　and　efficiency　of　vibration　attenuation　used　in　civil　engineering.　The　motion　equation　of　the　DTLCD-single-degree-of-freedom　(DTLCD-SDOF)　system　under　harmonic　excitation　was　established,　of　which　the　dynamic　magnification　factor　(DMF)　was　derived.　Then,　an　optimization　strategy　and　evaluation　function　was　proposed　to　judge　the　parameters　of　DTLCD,　and　a　parameter　optimization　program　written　in　Matlab　was　used　to　optimize　DTLCD.　Effects　of　each　parameter　on　dynamic　magnification　factor　(DMF)　were　discussed,　as　well　as　the　robustness　of　DTLCD　when　the　damping　ratio　and　frequency　were　changed.　Finally,　the　effectiveness　and　robustness　of　DTLCD　was　compared　with　that　of　the　TMD,　TLCD　and　DTMD.　The　theoretical　and　numerical　results　showed　that　the　effectiveness　of　DTLCD　was　much　better　than　of　the　TMD　and　TLCD,　and　was　the　same　as　that　of　DTMD;　meanwhile,　DTLCD　had　the　best　robustness　in　terms　of　perturbation　of　structure　frequency.　It　was　concluded　that　DTLCD　is　a　very　effective　method　of　vibration　control.　©　2016,　Editorial　Department　of　JVMD.　All　right　reserved.
