Generate isolated pad footing bar bending schedules with main and distribution bar cutting lengths, hook deductions, total rebar weights, and shape codes.
Formula and method
Generates isolated pad footing bar bending schedules with clear cover deductions, standard 90° hook developments, and total steel weight.
L_{\text{cut}} = L_{\text{footing}} - 2C_c + 2L_{\text{hook}} \quad , \quad W = L_{\text{cut}} \times N \times \frac{d^2}{162.2}
Add vertical hook or bend-up development lengths at both ends.
Calculate bar counts across both directions: (Span / Spacing) + 1.
Calculate steel weight using unit weight formula d² / 162.2 kg/m.
Frequently asked questions
How does the Footing BBS Calculator work?
Generate isolated pad footing bar bending schedules with main and distribution bar cutting lengths, hook deductions, total rebar weights, and shape codes. Enter your project parameters in either Metric or US Imperial units to calculate immediate results.
Are calculations compliant with building codes?
Calculations reference standard design methodologies (e.g. ACI 318, ASTM, BS 8666, and Terzaghi). Calculations provide preliminary planning values and must be verified by a licensed engineer for final construction drawings.
Can I use both Metric and US Imperial units?
Yes, CivilMath calculators provide full dual-unit capability. Select your preferred measurement standard at the top of the calculator input interface.
