Determine the amount of rebar needed for the grade beam in Problem 47. Allow for two inches of cover and ignore waste.
What will be an ideal response?
The ties are 8 inches (12? – 2 × 2?) by 10 inches (14? – 2 × 2?). The length of the ties is 36 inches (8? + 10? + 8? + 10?). The number of ties is calculated as follows:
Number of spaces = 20? × 12 in per ft / 8? = 30 spaces
Add 1 to get the number of ties – Use 31 ties
Total length of ties (lf) = 31 ties × 3? = 93 lf
Total weight of ties (pounds) = 93 lf × 0.376 pounds per lf = 35 pounds
The horizontal bars are 20 feet long calculated as follows:
Total length of horizontal bars (lf) = 4 × 20? = 80 lf
Total weight of horizontal bars (pounds) = 80 lf × 1.043 pounds per lf = 83 pounds
Total weight of rebar (pounds) = 35 pounds + 83 pounds = 118 pounds
