6. A W12x53 has been selected as a compression member for a single-story building design. The member is made of A992 Steel. The member is 20' long, fixed at the bottom

and pinned at the top in both axes. The member is braced against flexure at the midpoint in the minor axis only. The member is braced against torsion in both axes at the midpoint (In other words, flexural unbraced length is greater than or equal to the torsional unbraced length) If the DL= 150 kips, what is the maximum LL that can be applied to the column? Use LRFD and ASCE 7-22 Load Combos. (25 points)
