Framing & StructuralQuestion 342 of 700
CALCULATION: A sill plate on a 30-foot wall uses anchor bolts spaced at the 6-foot maximum, with a bolt required near each end. Approximately how many anchor bolts are needed along that wall?
a.4 bolts
b.5 bolts
c.6 bolts
d.10 bolts
Explanation
With bolts at 6 feet on center over 30 feet, the spacing gives 30/6 = 5 intervals, which needs 5 + 1 = 6 bolts to also place one near each end. Four or five bolts would leave spacing or end distances too great, and ten bolts far exceeds the 6-foot maximum spacing.
