Determine the amount of rebar needed for two of the piers shown in Figure 11.40. Allow for two inches of cover.
What will be an ideal response?
The dowels are part of the footing rebar. The ties are 8 inches (12? – 2 × 2?) square. The tie length is 32 inches (4 × 8?).
Number of spaces = 3? / 3? = 12 spaces
Add 1 to get the number of ties – Use 13 per column, a total of 26 (13 × 2)
Total length of ties (lf) = 26 ties × 32? / 12 in per ft = 69.3 lf
Total weight of ties (pounds) = 69.3 lf × 0.376 pounds per lf = 26 pounds
