Slab thickness, span lengths, live and dead loads, concrete and steel properties, support conditions.
Predicted crack width (pass/fail against code limit), immediate and time-dependent deflection. 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. Slab thickness, span lengths, live and dead loads,
Column dimensions, reinforcement ratio (ρg), number and size of bars, axial load (Pu), moments (Mux, Muy), unbraced length, end conditions. For the curious: start with a simple beam
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.
For professionals: build a curated library of verified spreadsheets. They will become your fastest, most transparent design companions.
