Question
Columns for the given frame will support factored loads of 500 kips each. The columns bend about their weak axis within the plane of the page. Within the plane of the page, cross-bracing prevents sidesway of the frame. Out of the plane of the page, sidesway is uninhibited and the columns bend about their strong axis. The columns are fixed at their base in both directions. The connection of the columns to the cross-beam should be treated as a pinned connection Determine the lightest weight W10 column size that will work for this frame. Utilize the design aids available in the AISC code to simplify this work. If you use the aids properly, then you should not have to check the column capacity using the equations from AISC section E3. 25 P 500 kip Pu 500 kipExplanation / Answer
Effective length of column about minor axis,given the column is fixed-pinned = 0.707*13=9.19 ft
design load on column = Pu=500 kips
From Table 4-1,the lightest w10 section that has compression load capacity greater than 500 kips for a effective length of 9.19 ft about minor axis is W10x49
Therefore,the required section is W10x49
