Shear Strength of a Cold-Formed Steel Sheet in Bolted Connections Using Oversized Holes
Publication: Journal of Structural Engineering
Volume 139, Issue 5
Abstract
The North American specifications for the design of cold-formed steel (CFS) structural members provides equations for determining the sheet shear strength in bolted connections when standard holes are used. In applications of oversized holes, the specification requires experimental analysis to be conducted to ensure satisfactory performance. A research project was recently completed at the University of North Texas to investigate the behavior and performance of CFS bolted connections using oversized holes. This paper presents the findings on the sheet shear strength for oversized hole applications. The studied parameters in this research included the following: sheet thickness from 0.762 to 2.997 mm; connection type of single shear and double shear with a single bolt; and bolt diameters of 6.4, 9.5, 12.7, and 15.9 mm. The experimental results indicate that the use of oversized holes without a washer did not significantly weaken the sheet shear strength. Recommendations are provided for predicting the nominal sheet shear strength.
