Determine the amount of rebar needed for the column shown in Figure 11.41. Allow for three inches of cover.
What will be an ideal response?
The dowels are part of the footing rebar. The ties are 30 inches (36? – 2 × 3?) by 138 inches (144? – 2 × 3?).
Length = 30? + 138? + 30? + 138? = 336? / 12 in per ft = 28?
Number of spaces = 120? / 6? = 20 spaces
Add 1 to get the number of ties – Use 21
Total length of ties (lf) = 21 ties × 28? = 588 lf
Total weight of ties (pounds) = 588 lf × 1.502 pounds per lf = 883 pounds
The vertical bars are 117 inches long (120? – 3?).
Total bar length (lf) = 28 bars × 117? per bar / 12 in per ft = 273 lf
Total bar weight (pounds) = 273 lf × 4.303 pounds per lf = 1,175 pounds
Total weight (pounds) = 883 pounds + 1,175 pounds = 2,058 pounds
