Abstract：This article conducts bending tests on 7 groups of 11 full-scale composite wall panel specimens,with frameless keel,panel thickness,loading direction,number of horizontal keels,presence or absence of openings,span,and width as basic param-eters.The failure mechanism,load displacement curve,deformation distribution curve,and steel keel load strain curve of each speci-men are obtained.The results show that the presence or absence of frame keel,thickness difference of panel,number of horizontal keels,span and width have a significant impact on the ultimate bending bearing capacity of the specimen.The different loading di-rections result in significant differences in the failure modes of the specimens.The opening of the specimen does have a certain impact on its ultimate bearing capacity,but it still meets the requirements for use.Under normal use ultimate load,the bearing ca-pacity and deformation of the specimen can meet the requirements of use and have a large safety margin.
