A shear wall line is 24 feet long, and hold-downs are required at 12-foot intervals including both ends. How many hold-down locations are needed?
Correct Answer
A) 3 locations.
A 24-foot line divided by 12 feet gives 2 spaces; including both ends requires 3 hold-down locations.
Why This Is the Correct Answer
A 24-foot line divided by 12 feet gives 2 spaces; including both ends requires 3 hold-down locations.
Why the Other Options Are Wrong
Option B: 2 locations only.
2 locations only. is below the supported result for hold-down layout calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 4 locations total.
4 locations total. is above the supported result for hold-down layout calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 5 locations total.
5 locations total. is above the supported result for hold-down layout calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
