For the portal frame shown below, all members are made of A992 Steel and are oriented for strong axis bending in the plane of the frame. Both columns are braced in the out-of-plane direction at the top and bottom ends. Column base connections are perfect pins (use G = ā) and beam-to-column connections are rigid (moment resisting). Find the lightest A992 W14 for Columns A and B that meet all LRFD limit states for members in compression. Pā = 1170 k Pā = 1170 k W21x93 Col A Col B 30.0' 12.0'
