All of the columns for these problems are assumed to be in frames that are braced against side- sway. Each problem is solved by both the LRFD and the ASD procedures. 6-1 to 6-3. Use a trial-and-error procedure in which a KLIr value is estimated, the stresses de Fe, and F,/2. determined from AISC Table 4-22, required areas calculated and trial sections selected and checked and revised if necessary. 6-1. Select the lightest available W10 section to support the axial compression loads PD = 100 k and PL = 160 k if KL = 15 ft and A992, Grade 50 steel is used. (Ans. W10 x 49, LRFD and ASD) 6-2. Select the lightest available W8 section to support the axial loads Pp = 75 k and PL = 125 k if KL = 13 ft and F, = 50 ksi. 6-3. Repeat Prob. 6-2 if F, = 36 ksi. (Ans. W8 X 48, LRFD and ASD) -
