## Rebar Layout **Bars in One Direction = floor((Dimension - 2 x Offset) / Spacing) + 1** Rebar is placed in a grid pattern with bars running in both directions. The edge offset (typically 2 to 3 inches) keeps rebar away from the form edges for adequate concrete cover.

हल किया गया उदाहरण

20 x 12 ft slab, 12-inch spacing, 3-inch edge offset.

  1. 01Net length = 240 - 6 = 234 in
  2. 02Net width = 144 - 6 = 138 in
  3. 03Bars along length = floor(138/12) + 1 = 12
  4. 04Bars along width = floor(234/12) + 1 = 20
  5. 05Total = 12 + 20 = 32 bars
