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.

Maximum service load that can be applied without
exceeding the allowable capacity on yielding on
gross area of the tension member (double angle).
Maximum service load that can be applied without
exceeding the allowable fracture on the net area
of the tension member (double angle).
Maximum service load that can be applied without
exceeding the allowable block shear strength.
Considering the weld metal and base metal
strength, calculate the maximum service load that
can be applied.
Design a welded connection for an MC9x23.9 of A572 Grade 50 steel connected to
a 3/8-inch-thick gusset plate (Figure 6). The gusset plate is A36 steel. Show your results on a
sketch, complete with dimensions.
