In　order　to　study　the　failure　mode,　seismic　behavior　and　deformation　capacity,　four　full-size　small　concrete　block　walls　with　different　structural　details　are　tested　under　low　cyclic　loadings.　Based　on　the　laboratory　experiment,　the　cracking　and　damage　process　of　the　walls　are　studied　and　the　initial　cracking　load　and　the　ultimate　load　for　the　walls　are　determined.　The　strain　of　the　reinforcing　bars　are　recorded　and　analyzed.　The　test　results　indicate　that　the　walls　are　easy　to　crack　even　if　they　can　take　rather　large　horizontal　loads.　Tie　steel　fabric　sheets　and　columns　can　improve　the　seismic　behavior,　and　enhance　deformation　capacity　to　prevent　brittle　failure　of　walls　with　openings　on　them.　The　ultimate　loads　of　the　walls　are　reduced　because　of　the　door　holes,　and　strengthening　measures　should　be　taken　in　order　to　improve　the　ductility　and　earthquake　resistance　capacity.
