A　tuned　mass　rocking　wall　(TMRW)-frame　structure　system　is　proposed　to　improve　the　energy　dissipation　ability　of　the　traditional　rocking　wall-frame　system.　Based　on　the　energy　dissipation　principle　of　the　traditional　tuned　mass　damper　(TMD),　a　TMRW　is　designed　with　proper　mass　and　stiffness　according　to　the　dynamic　characteristic　of　the　host　structure.　Firstly,　considering　the　presence　of　inherent　structural　damping,　the　dynamic　amplification　factor　of　the　main　mass　was　derived　from　the　dynamic　equations　of　the　TMRW　mechanism.　A　practical　design　table　was　then　obtained　after　parameter　study.　Secondly,　by　taking　a　six-story　frame　structure　as　an　example,　the　dynamic　time-history　analysis　was　conducted　to　study　TMRW＇s　seismic　performance.　The　inter-story　drift　ratios　of　the　TMRW-frame,　the　traditional　rocking　wall-frame,　and　the　frame　structures　were　compared,　and　the　seismic　responses　of　the　controlled　and　uncontrolled　structures　were　also　compared.　The　results　demonstrate　that　the　TMRW　can　effectively　reduce　the　inter-story　displacement　of　the　host　structure,　and　the　lateral　deformation　mode　of　the　host　structure　tends　to　be　more　uniform.　However,　compared　with　the　traditional　rocking　wall-frame　system,　the　proposed　TMRW　has　less　ability　on　coordinating　deformation.
