y loaded connection is subjected to a service-load shear force of 250 kN and a service-load tensile force of 500 kN. The loads are 60% dead load and 40% live load. The fasteners will be in single shear and bearing strength will be controlled by a 10-mm-thick connected part of A36 steel. Assume that all spacing and edge distances are satisfactory, including those that permit the maximum nominal bearing strength of 2.4dtFu to be used. Determine the required number of 16-mm diameter Group A bolts for the following cases: (a) a bearing-type connection with threads in the plane of shear and (b) a slip-critical connection with threads in the plane of shear. All contact surfaces have clean mill scale. Consider this to be a preliminary design so that no consideration of prying action is necessary. Consider LRFD and ASD.
