Calculadora de Espaçamento de Chumbadores — Formula
## 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**

Exemplo Resolvido
40 ft wall, 6 ft max spacing, 12 in from ends.
- Interior length = 40 - 2 = 38 ft
- Interior sections = ceil(38/6) = 7
- Interior bolts = 7 + 1 = 8
- Total = 8 + 2 end bolts = 10 anchor bolts
