1. Determine the gross and net areas for an 8×1/2 in. plate with a single line of standard holes for 3/4 in. bolts. 2. Determine the gross and net areas for an L5×5×1/2 with two lines, one in each leg, of standard holes for 3/4 in. bolts. 3. A single L6×6×1 is used as a tension brace in a multi-story building. One leg of the angle is attached to a gusset plate with a single line of three 7/8 in. bolts at a spacing of 3 in. Determine the shear lag factor (consider Case 2 and Case 8) and effective net area. 4. Determine the available strength of a C8×11.5 attached through the web to a gusset plate with ten 3/4 in. bolts, in two lines of five bolts, at a 3 in. spacing. Use A992 steel. Considering yielding and net section rupture, determine the (a) design strength by LRFD
