Monotonic shear tests of cold-formed steel wall frames with sheathing
Abstract This research is focused on the experimental study of the structural strength of cold-formed steel wall frames with sheathing under monotonic shear loading. Two aspect ratios, 1.0 and 2.0 were utilized in the design of wall specimens. Three different kinds of sheathing material, gypsum board, calcium silicate board, and oriented-strand board, with two different thicknesses (9 and 12mm) were adopted in the test specimens. The ultimate strength, stiffness, energy absorption, and ductility ratio were studied for each test specimen. In final, the ductility ratios of the cold-formed steel wall frames similar to the wall configuration conducted in this study are proposed.
Research highlights ► Cold-formed steel wall stud assemblies are generally used as major load-carrying and shear-resistance units in the light-weight steel constructions. ► There is a lack of available data to create a design, because of the complexity of wall framing system. ► This research focused on the study of the stiffness, energy absorption, and ductility ratio of cold-formed steel framing wall, as well as the influence of strength affected by the sheathing material under monotonic shear loading condition. ► An equation to predict the ultimate shear strength of cold-formed steel framing wall is proposed in this paper, and the suggested ductility ratios of the wall sheathed with calcium silicate board, gypsum board, or oriented-strand board are also proposed in this study.
