In　order　to　study　the　seismic　performance　of　precast　short-leg　shear　wall　connected　by　grouting　sleeves　(PSSW),　the　three-dimensional　numerical　model　was　established　by　using　the　experiment　of　PSSW　subjected　to　low　cyclic　loading.　Based　on　good　agreement　between　numerical　results　and　experimental　results,　the　numerical　analysis　models　with　different　structural　parameters　of　axial　compression　ratio　and　splicing　position　were　designed　in　detail,　and　the　effects　of　various　parameters　on　the　seismic　performance　of　PSSW　were　analyzed.　The　results　show　that　the　PSSW　exhibits　wide　and　stable　hysteresis　loops,　indicating　a　satisfactory　hysteretic　performance　and　an　excellent　energy　consumption　capacity.　With　the　increase　of　the　axial　compression　ratio,　the　shear　capacity　of　horizontal　splice　seam　is　improved,　but　the　ductility　coefficient　and　total　energy　consumption　decrease　obviously.　The　most　disadvantageous　position　of　PSSW　can　be　effectively　avoided　by　changing　the　position　of　the　post　pouring　seam.　The　bearing　capacity　of　the　specimens　is　basically　stable,　and　the　energy　consumption　increases　significantly,　so　the　post　pouring　seam　of　precast　wall　is　recommended　to　be　far　away　from　the　bottom　section　of　the　wall.　In　addition,　the　failure　mechanism　of　different　splicing　positions　was　analyzed　in　detail.　©　The　Author(s)　2020.
