Abstract
In general, shear walls with corrugated thin steel sheets in residential cold-formed steel framing have undesirable lateral deformation capacity as a result of the buckling of the corrugated sheets or the pull-out of the screws used to connect the corrugated sheets to the cold-formed steel members. The purpose of the present study is to provide corrugated shear walls with large deformation capacity by designing" bearing-failure critical" screw joints. The validity of this design was experimentally investigated using a series of in-plane cyclic racking shear tests of corrugated sheet shear walls. The frame member thicknesses were set as a test parameter to confirm a failure mode of screw connections. The influences of using screws with washers and low-elongation steel are also confirmed. The tests showed that the local bearing failures by suppressing the screw pull-out provide a shear wall with a stable and ductile behavior. It was also shown that the deformation capacity of the shear wall can be improved by adding washers to the screws or by using a low-elongation steel for the corrugated sheet.
