Test Research on Self-Tapping Screw Joints of Cold-Formed Steel Frame Shear Walls

Abstract:

Two different types, one is the OSB panel perpendicular to the cold-formed thin steel and another the OSB panel parallel to the cold-formed thin steel, of self-tapping screw joints of cold-formed steel frame shear walls are tested under the monotonic loading. The load-displacement curves of the test specimens are obtained and the ultimate loads Fu and the corresponding displacements δu of two different types are analyzed. Fianlly, the conclusion that the influence from the direction between OSB and cold-formed thin steel to the performance of tapping screw joints is not significant is pointed up.
