## Anchor Bolt Layout The IRC requires anchor bolts no more than 6 feet apart, with one bolt within 12 inches of each end of the sill plate and each side of openings. Seismic zones may require closer spacing (4 ft) or larger bolts. **Interior bolts = ceil(Interior Length / Spacing) + 1** **Total = Interior + 2 end bolts**

हल किया गया उदाहरण

40 ft wall, 6 ft max spacing, 12 in from ends.

  1. 01Interior length = 40 - 2 = 38 ft
  2. 02Interior sections = ceil(38/6) = 7
  3. 03Interior bolts = 7 + 1 = 8
  4. 04Total = 8 + 2 end bolts = 10 anchor bolts
