In　order　to　study　the　effect　of　grid　spacing　on　seismic　performance　of　grid　shear　wall,　the　quasi-static　test　and　finite　element　analysis　were　carried　out　on　the　grid　shear　wall　with　small　shear　span　ratio　with　different　center　spacing　of　two　vertical　elements.　The　results　show　that　the　failure　modes　of　grid　shear　walls　with　the　same　center　distance　of　horizontal　elements　and　200　mm　and　300　mm　center　distance　of　vertical　elements　are　different.　The　concrete　at　the　bottom　and　corner　of　the　grid　shear　wall　with　the　center　distance　of　vertical　element　200　mm　is　damaged,　and　the　failure　mode　is　shear　compression　failure.　The　grid　shear　wall　with　300　mm　center　distance　of　vertical　element　moves　and　slips　along　the　diagonal　main　diagonal　crack,　and　the　failure　mode　is　shear　tension　failure.The　ultimate　drift　ratio　of　the　two　specimens　is　about　1　/　100,　and　the　stiffness　and　strength　capacity　of　the　grid　shear　wall　with　the　center　distance　of　vertical　element　of　300　mm　are　slightly　larger.　The　finite　element　simulation　results　are　in　good　agreement　with　the　experiment,　which　verifies　the　effectiveness　of　the　simulation　method.　A　method　for　calculating　the　reduction　thickness　of　grid　wall　with　different　spacing　is　proposed.　The　grid　shear　wall　can　be　equivalent　to　solid　shear　wall　to　calculate　the　stiffness　and　strengh　capacity.　©　2023　Science　and　Technology　Periodical　Press.　All　rights　reserved.
