In　order　to　study　seismic　performance　of　the　multi-ribbed　composite　slab　structure　with　large　space　at　the　bottom,　the　low-cyclic　loading　experiments　of　two　1/2　models　of　multi-ribbed　composite　wall　supported　on　frame　structure　were　studied.　The　failure　process,　the　hysteretic　characteristic　of　vertex　lateral　displacement,　the　inter-story　displacement,　the　skeleton　curve,　and　steel　load-strain　curves　of　the　members　under　the　low-cyclic　loading　were　compared　and　analyzed.　The　stiffness　degradation　and　residual　deformation　ratio　of　the　specimens　was　discussed.　The　results　show　that　the　structure　has　good　seismic　performance　due　to　the　unique　nested　construction　form.　The　failure　mode　and　the　trend　of　stiffness　degradation　of　the　structure　with　opening　are　consistent　with　those　of　structures　without　opening.　Both　structures　have　good　displacement　ductility,　collapse-resistant　capacity　and　repairability.
