A C8 × 11.5 is connected to a gusset plate with 22 mm diameter bolts as shown. The steel is A572 Grade 50. If the member is subjected to dead load and live load only, what is the total service load capacity if the live-to-dead load ratio is 3? Assume that Ae = 0.85An. a. Use LRFD. b. Use ASD. Properties of A572 Grade 50: Fy = 345 MPa Fu = 448 MPa C8 × 11.5 Properties of C8 x 11.5: Ag = 2,181 mm? br = 57.4 mm d = 203.2 mm Lw = 5.6 mm l = 9.9 mm
