WebThe bearing stress state can be complicated by the presence of nearby bolt or edge. The bolt spacing and edge distance will have an effect on the bearing stress. 7.3 – BEARING STRENGTH, SPACING, AND EDGE-DISTANCE REQUIREMENTS Bearing stress effects are independent of the bolt type because the bearing stress acts on the connected plate … Webconsideration of edge distance, sometimes referred to as tearout) and bolt shear. Sufficient ductility is assumed. Returning to our example, applying the user note results in the …
WebJun 10, 2013 · In typical configurations of a single column of bolts, only one bolt may experience tearout, but it is not clear how to satisfy statics under eccentricity (horizontal components must sum to zero) when for example, the lower bolt experiences tearout and the upper bolt experiences bearing. WebFurther, Section J3.10c of the AISC Specification, which considers “Bearing and Tearout Strength at Bolt Holes”, refers the case when bolts pass fully through an unstiffened HSS member, as is the case with a through-bolt …

Webhole distance minus the bolt diameter plus 1/8 in or the distance from the center of bolt hole to the edge of plate minus one half of the bolt diameter plus 1/8 in. m = the number of shear planes t = thickness of the thinner plate material being connected, in B. Bolt hole geometry. The placement of bolt holes is prescribed by AISC.
WebDowelled connections transfer the force between members through a combination of dowel bearing and bending of the dowel fastener. Bolts must be structural quality bolts, equal to or better than ANSI/ASME Standard B18.2.1. Bolt holes must be a minimum of 1/32 inch and a maximum of 1/16 inch larger than the bolt diameter.
