Seismic　performance　of　the　multi-ribbed　composite　wall　structure　with　large　space　at　the　bottom,　combined　with　the　new　oblique　frame-grid　used　in　multi-ribbed　structure　was　studied　in　this　paper.　The　pseudo-static　experiment　of　two　1/2-scale　multi-ribbed　composite　wall　supported　on　frame　shear-wall　structure　was　conducted.　Under　the　low　reversed　cyclic　loading,　the　failure　process　and　force　transfer　mechanism　of　the　oblique　and　orthogonal　frame-gird　specimens　was　analyzed.　The　hysteretic　characteristic　of　inter-story　displacement,　steel　load-strain　curves　of　the　members,　residual　deformation　ratio　of　the　specimen　was　discussed.　The　results　show　that　the　structure　have　good　seismic　performance.　The　unique　oblique　frame-grid　design　can　improve　the　overall　ductility,　deformation,　collapse-resistant　capacity　and　reparability.　©,　2015,　Harbin　Institute　of　Technology.　All　right　reserved.
