Determine the maximum service axial live load that can be supported by ASD method. A. 469.697 C. 1071.678 B. 429.452 D. 1060.203 Situation 8 - A W12x79 of A573 Grade 60 (Fy = 415 MPa) steel is used as a compression member. It is 8 m long, fixed at the top and bottom, and has additional support in the weak direction 3 m from the top. Properties of the section are A = 16,800 mm2, Ix = 258.6 x 106 mm4, Iy = 84.375 x 106 mm4 22. Calculate the effective slenderness ratio with respect to strong axis buckling.
