Design Spreadsheet Excel Free Download: Reinforced Concrete

Column dimensions, reinforcement ratio (ρg), number and size of bars, axial load (Pu), moments (Mux, Muy), unbraced length, end conditions.

Predicted crack width (pass/fail against code limit), immediate and time-dependent deflection.

Spreadsheet suggested 0.3 m thickness (instead of assumed 0.25 m) to satisfy punching shear. Also showed that minimum steel (0.0018bh) governed over required flexural steel. Engineer saved a potential failure at a negligible cost. The spreadsheet’s calculation sheet was printed, signed, and included in the construction permit. reinforced concrete design spreadsheet excel free download

"Two-Way Slab Design (Direct Design Method).xls" – follows ACI 318's DDM, including panel moment distribution. 4. Footing Design (Isolated Square or Rectangular) What it does: Sizes the footing based on soil bearing capacity, checks one-way and two-way (punching) shear, designs flexural reinforcement, and checks development length.

Column loads, footing dimensions (trial), soil allowable bearing pressure, concrete cover, rebar details. Also showed that minimum steel (0

For the curious: start with a simple beam flexure sheet today. In one hour, you will have a working tool and a deeper respect for the engineers who code in Excel cells. Start with the ACI 318-14 Rectangular Beam Design from civilengineeringspreadsheets.com. Test it with Example 4.1 from your favorite concrete design textbook. Then adapt it to your next project. Happy designing. This feature is for informational purposes. Always verify all engineering calculations with a licensed professional engineer and applicable local building codes.

Downloaded "Isolated Footing Design.xls" from a civil engineering forum. Input wall load (65 kN/m), soil bearing (150 kPa), concrete C25/30, steel S420. "Two-Way Slab Design (Direct Design Method)

Today, have democratized access to professional-grade tools. Whether you are a student verifying a beam section, a young engineer checking column capacity, or a contractor designing a simple lintel, these spreadsheets offer speed, transparency, and reliability—at zero cost.

"Isolated Footing Design.xls (ACI 318-14)" – includes a settlement check option for sandy soils. 5. Crack Width and Deflection Verification What it does: For serviceability limit state (SLS) design. Computes crack widths per code formulas and long-term deflection considering creep and shrinkage.
