A　tuned　mass　rocking　wall　(TMRW)　is　a　passive　control　device　that　combines　the　merits　of　a　traditional　tuned　mass　damper　(TMD)　and　a　traditional　rocking　wall　(RW).　TMRWs　not　only　help　avoid　weak　story　failure　of　the　host　structure　but　can　also　be　regarded　as　a　largely　tuned　mass　substructure　in　the　building　structure.　Through　the　appropriate　design　of　the　frequency　ratio,　the　host　structure　can　dissipate　much　more　energy　under　earthquake　excitations.　In　this　paper,　the　basic　equations　of　motion　for　the　mechanical　model　of　an　SDOF　structure-rigid　rocking　wall　are　established,　and　the　optimization　formulas　of　frequency　ratio　and　damping　ratio　of　TMRW　are　derived.　Through　the　dynamic　elastoplastic　analysis　of　a　six-story　TMRW-frame　model,　the　applicability　of　the　derived　parameter　optimization　formulas　and　the　effectiveness　of　the　TMRW　in　seismic　performance　control　are　investigated.　The　results　demonstrate　that　the　TMRW　can　coordinate　the　uneven　displacement　angle　between　stories　of　the　host　structure.　Additionally,　the　TMRW　is　found　to　possess　the　merit　of　reducing　both　the　peak　and　root-mean-square　(RMS)　structural　responses　when　subjected　to　different　types　of　earthquake　excitations.
