Concrete　block　is　the　most　competitive　in　new　wall　materials.　For　further　researching　on　seismic　performance　of　masonry　structures,　this　paper　carries　out　test　research　on　6　specimens　under　cyclic　loading,　and　obtains　test　date　including　hysteretic　curve,　skeleton　curve,　bearing　capacity,　ductility　and　energy　dissipation　etc.　Major　influence　factors　are　listed　as　following:　constructional　column,　block　type　and　transverse　steel　bar.　According　to　observing　experimental　phenomenon　and　analyzing　test　results,　this　article　has　a　conclusion:　Constructional　column　is　an　important　structural　measure　in　masonry　structures,　it　can　restrain　concrete　block　bearing　wall　effectively.　Specimens　with　constructional　columns　and　transverse　steel　bars　have　good　seismic　behaviors　and　do　not　collapse　under　strong　earthquakes.　©　2011　IEEE.
