Experimental study on deflection performance under co-action of press, bending and shear of multi-ribbed composite wall

Based on static loading experimental study of the behaviors about co-action on press, bending and shear of the walls, studies were carried out to investigate performance of deflection and ductility, attenuation feature of resisting shear and moment stiffness of the wall. The results indicated that deflection of the wall are made up shear and bending deflection, and possess ‘bending-sheari type’. Elastic resisting shear and moment stiffness of the wall can be calculated with equivalent stiffness principle, converting composite wall into concrete shear-wall. In the normal use stage, elastic-plastic deflection of the wall would be enlarged nonlinear. The results can provide a support for study finite element model of the deflection performance under co-action of press, bending and shear, and establishing the calculation method of deflection of the walls.
