This　paper　references　the　structural　design　of　the　novel　oblique　frame-grid　multi-ribbed　composite　(MRC)　wall　in　studying　the　seismic　performance　of　frame-supported　MRC　(FSMRC)　walls.　Two　1/2-scale　FSMRC　wall　specimens　with　first　floors　composed　of　frame-shear　walls　and　second　floors　composed　of　MRC　walls　were　tested　under　cyclic　loading.　The　failure　processes　and　force-transfer　mechanisms　of　both　the　orthogonal　and　the　oblique　frame-grid　specimens　were　then　investigated.　Concurrently,　the　hysteresis　of　the　vertex-horizontal　displacement　and　inter-storey　displacement,　the　skeleton　curves,　the　loading-strain　curves　of　the　reinforcing　bars　of　the　members,　and　the　residual　deformation　ratios　of　the　specimens　were　analysed.　The　results　indicate　that　the　FSMRC　wall　exhibited　good　seismic　performance　and　that　the　oblique　frame-grid　design　was　able　to　improve　the　overall　ductility,　deformation　capacity,　seismic　resistance　and　repairability　of　the　wall.
