Q.2 a. Determine the net area along route ABCDEF for C15x33.9(Ag=10in2) as shown in Fig. Holes are for %- in bolts. b. compute the design strength if A36 is used 0.650 in 14in 3in 0.400 in 9 in C15 x 33.9 3 in 14 in 2 in 0.650 in (b) (c) 141 3+2-040

Compute the nominal shear strength of an M107.5 of A572 Grad 65 steel.

Compute the nominal shear strength of an M1211.8 of A572 Grade 65 steel.

Select an American Standard Channel shape for the following tensile loads: dead load = 54 kips, live load = 80 kips, and wind load = 75 kips. The connection will be with longitudinal welds. Use an estimated shear lag factor of U = 0.85. (In a practical design, once the member was selected and the connection designed, the value of U would be computed and the member design could be revised if necessary.) The length is 17.5 ft. Use Fy=50 ksi and Fu=65 ksi. a. Use LRFD. b. Use ASD.
