Abstract

The main objective of this research was to determine the effect of slotted holes on the slip coefficient of high-strength bolted connections. Butt joints were used for the control specimens as well as for the test-specimens. The enclosed ply of the joint served as the pulling element and had standard round holes with a hole diameter 1/16-inch greater than the bolt diameter. The outer plies contained the slotted holes either parallel or perpendicular to the load. The slotted holes varied in length, using 0-lnch, 1/2-lnch, 3/4-lnch and 1-lnch as the tangent distance for the slots. The specimens with a tangent distance of 0-lnch served as the control specimens. Each type of joint was duplicated a minimum of three times for comparison purposes. This study was limited to 7/8-inch and 1-inch diameter bolts. A secondary objective of this research was to determine the effect of slotted holes on the ultimate shear stress of the bolts in the bolted connections previously described.
