1. An exterior beam-column in the first story of a proposed residential Building is loaded as follows: Axial Compressive Force P = 300 K Maximum End Moment Mx = = 58 K-FT The unbraced length of beam-column (L) = 18 feet The effective length factor K=1.0 Moment magnification factor B1 = 1.02 A W10x77 steel section is selected as a trial section for the design of the beam-column. (2 points) a) Determine the Effective Length of the Beam-Column. (3 points) b) Determine the value of Pr/Pc where Pr is the required (applied) axial compressive force. Pc =Pn/Sc is the allowable compressive force. (9 points) c) Using AISC Interaction Equation H1-1a or H1-1b whichever is applicable, and Manual Table 6-2 determine if the trial W10x77 section is adequate for the given load combination of axial compressive force and flexure. 16 points)
