Question 1: (Design Tension member) Design the x-bracing of a building, which is subjected to tension...
A double-angle tension member, 2L 3x2x 1/4, is subjected to a dead load of 12 kips, and a live load of 36 kips. It is connected to a gusset plate with one line of 3/4-inch-diameter bolts through the long legs. Is this member safe? Assume U=0.85. Fy =36 ksi and Fu = 58 ksi.

2. (50 pts) Design an A36-steel tension member 16 ft long consisting of two channels, bolted through their webs to a single 1 inch gusset plate, to transmit 75 kips DL and 93 kips LL. The bolts are 7/8 in. Bolt spacing 4 inch and bolt edge distance 3 inch. In addition to checking block shear in the channels, design the thickness of the gusset plate to resist block shear.
2. (30 pts) Determine the block shear strength of the tension member shown below. Bolts diameter = 7/8 in, A36 steel is used (Table 2-4 XN, A16 s 58 kse DO 3232 -in. bolts 19 (3) /8" bolts 3" bolt spacing (fy = 36 ksi P. 2-487 (Table 1-7) Ag = 2.50 in ² p. 1-48 - 1.00 in t. 3/8" And = [3.5"-(7/6" + /6")] (3/8") = 10.94 in?

Both the member and the gusset plate are A36 steel C79.8 O o o a) (15%) Compute the available block shear strength of the tension member for LRFD b) (10%) Compute the available block shear strength of the gusset plate for LRFD t-217 Wh-diameter bolts
Question 1: Three tension members are shown below. Assume the strength of the member controls and not the connecting element. Each member is made from A36 steel. All bolts are spaced at 3.0 inches unless the sketch indicates otherwise. The distance from the centerline of the last bolt to the end of the tension member is 2.0 inches unless the sketch indicates otherwise. The required sketches described below are 20% of the points Include the following: For the area calculations...
