Out-of-plane　under　lateral　low　cyclic　loading　test　and　in-plane　loading　test　on　two　kinds　of　small　concrete　hollow　block　composite　walls　with　different　joint　fashion　are　carried　out　in　order　to　know　the　cracking　and　the　developing　process　of　the　crack,　to　analyze　the　strain　change　of　the　joint　bar　and　to　research　the　seismic　and　deformation　behavior.　The　results　of　out-of-plane　loading　tests　show　that　the　ductility　of　these　two　kinds　of　walls　is　about　the　same,　the　wall　jointed　with　bar　can　improve　the　entirety　of　composite　walls　and　the　wall　jointed　with　steel　wire　netting　is　better　at　increasing　tension　strength　of　the　attachment　wall.　This　paper　compares　the　wall　under　the　in-plane　loading　after　out-of-plane　loading　with　the　wall　under　in-plane　loading　only,　the　result　shows　that　the　out-of-plane　loading　weakens　the　rigidity　of　the　wall,　and　the　crack-loading　debases,　but　the　ultimate　carrying　capacity　and　ductility　change　little.
