Bars Along Length vs Slab/Wall Length

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.
- 01Net length = 240 - 6 = 234 in
- 02Net width = 144 - 6 = 138 in
- 03Bars along length = floor(138/12) + 1 = 12
- 04Bars along width = floor(234/12) + 1 = 20
- 05Total = 12 + 20 = 32 bars
अक्सर पूछे जाने वाले प्रश्न
What rebar spacing is standard for slabs?
Residential slabs typically use 12 or 18-inch spacing. Structural slabs and foundations may require 6 or 8-inch spacing. Check your structural drawings for the specified spacing.
How much concrete cover is needed over rebar?
For slabs on grade: 3 inches on the bottom. For walls: 1.5 inches. For exposed concrete: 2 inches. Cover protects rebar from moisture and corrosion.
