Product Description
Product Overview
This Excel workbook designs continuous concrete wall footings (strip foundations) per unit length in accordance with ACI 318-25 and ASCE/SEI 7-22. It supports both reinforced and unreinforced plain concrete footing checks, evaluates overturning/sliding eccentric soil pressures, and verifies shear and bar development length in US or SI units.

Design Checks & Calculation Scope
ASCE 7-22 Soil Bearing & Sliding
Evaluates service load combinations (dead, live, roof/snow, 0.6W wind, 0.7E seismic) for allowable soil bearing pressure, eccentricity e ≤ B/6, and sliding safety factor.
One-Way Beam Shear (Sec. 13.2.6.2)
Checks critical factored one-way beam shear at distance d from wall face using φ = 0.75 and λs = 1.0 for shallow foundations (φVc = 0.75 · 2 √(f’c) · b · d).
Plain Concrete Mode (Sec. 14.5)
Includes an option to evaluate unreinforced strip footings per ACI 318-25 Chapter 14 in flexure and one-way shear using strength reduction factor φ = 0.60 (Table 21.2.1(g)).
Cantilever Flexure, Shrinkage & Anchorage
Sizes main transverse flexural bars (φ = 0.90), longitudinal shrinkage steel with the 0.0014 floor (Table 24.4.3.2), and straight or 90-degree hooked development length with grade factor ψg.

Building Code Standards & Regional Applicability
Strength reduction factors (φ), capacity equations, and reinforcement detailing limits follow ACI 318-25 / ACI 318M-25 and ASCE/SEI 7-22. Engineers working under national codes derived directly from ACI 318 can adjust concrete strength, steel yield grade, load factors, and bar sizes directly in the input cells:
| Region / Country | Applicable National Standard | Engineering Application |
|---|---|---|
| United States & Territories | IBC 2024 / ACI 318-25 / ASCE 7-22 | Matches current IBC / ACI 318-25 building code provisions in US customary units (kips, in, ksi). |
| Saudi Arabia & GCC | SBC 304 (Saudi Building Code) | SBC 304 adopts ACI 318 strength reduction factors (φ) and detailing provisions directly for EPC and commercial submittals. |
| Philippines | NSCP 2015 (ACI 318 based) | Uses equivalent strength design, shear-friction, and seismic detailing provisions; metric or customary bar inputs supported. |
| Indonesia | SNI 2847:2019 / SNI 1726:2019 | SNI 2847 adopts ACI 318 provisions with compatible flexural, shear, deep-beam, and special wall checks. |
| Colombia & Latin America | NSR-10 / NEC-15 / NTC-C | Follows the ACI 318 framework for seismic confinement, coupling beams, shear walls, and spread foundations. |
| Canada & International | CSA A23.3 / International Projects | Useful as an ACI 318-25 design check on international industrial, oil & gas, and plant foundations. |
Spreadsheet Notes & Engineer Responsibility
- Editable Open Formulas: All worksheets use native Excel formulas without VBA macros or password-locked sheets.
- Worked Example Included: Pre-populated sample inputs and pass/fail checks allow you to review the calculation flow immediately before entering project loads.
- Professional Responsibility: This spreadsheet is an engineering design aid. Input loads, geotechnical parameters, site seismic criteria, reinforcement detailing, and final code compliance remain the responsibility of the Engineer of Record.
