The　paper　intends　to　study　the　seismic　performance　of　the　frame-supported　multi-ribbed　composite　wall　(FSMRC　wall)　with　large　space　at　the　bottom　and　with　that　purpose,　it　conducts　low-reversed　cyclic　loading　experiment　to　two　such　specimens,　with　their　scales　reduced　by　1/2　of　the　prototypes.　Afterwards,　the　paper　looks　into　the　major　parameters　-　failure　process,　the　hysteresis　of　the　vertex-horizontal　displacement　and　of　inter-storey　displacement,　the　skeleton　curves　and　the　loading-strain　curves　of　the　members＇　reinforcing　steels　-　of　the　specimens,　both　with　and　without　holes,　and　then　carries　out　comparative　studies　on　the　results.　On　this　basis,　the　stiffness　degradation　and　the　residual　deformation　ratio　are　discussed,　and　the　experiment　results　stand　as　the　following:　the　structure　as　a　whole　delivers　an　extraordinary　seismic　performance,　thanks　to　the　unique　layer-by-layer　embedded　upper　design.　It　should　be　noted　that　the　failure　process　and　the　stiffness　degradation　of　both　specimens,　with　and　without　the　holes,　are　found　to　be　roughly　consistent;　at　the　same　time,　both　has　proven　to　be　fairly　good　in　terms　of　displacement　ductility,　collapse　resistance　and　repairability.
