A W14 x 109 of 50 ksi steel, 16 feet long, is to be investigated for use as a beam-column in an unbraced frame. First-order analyses of the frame were performed for both the sway and the nonsway cases. The factored loads and moments corresponding to one of the load combinations to be investigated are given for this member in the following table: Type of analysis Nonsway Sway P, (kips) 520 30 Mtop (ft-kips) 82 40 Mbot (ft-kips) 98 45 Bending is about the x-axis, and all end moments are in the same direction. Assume that Pnt Pstory Pe story Pe₁ The effective length factors are Kx = 0.85 for the braced cased, Kx = 1.2 for the unbraced case, Ky = 1. Use LRFD and Table 6-2 of the AISC Manual to determine whether this member satisfies the appropriate AISC interaction equation.
