Problem 7: The load that will be applied to the connection shown has a live load - to - dead load
ratio of 3.0. Investigate all limit states. All structural steel is A36, and the weld is a 1/4-inch fillet
weld with E70 electrodes. Note that the tension member is a double-angle shape, and both of the
angles are welded as shown. Use ASD. Determine the following.
