For the bolted connection shown in Figure, Compute the design strength ftPn, neglecting block shear. The angle is made of A36 steel (fy-36 ksi, fu-58 ksi) The bolts are 1 in diameter. Assume U=0.9 + S S S S S L6x3.5x(3/8) S s=2 in 1.25" 2.5" 2,25" BONUS (10 Points) Assuming that the fracture of the net section controls failure, what must be the minimum horizontal spacing, s, to maximize the fracture design strength of the connection? (Do not consider yielding of the gross section.)
