Excel design sheets for beams, columns, slabs and footings, built directly to ACI 318-19 — with every check traceable back to the section it comes from.
The same element set, rebuilt from the ground up for ACI's strength reduction factors, load combinations and reinforcement limits — not a Eurocode sheet with the units swapped. φ is never assumed: each sheet computes the net tensile strain and interpolates φ through the transition zone.
Built to the parts of 318-19 that changed. Where a member carries no shear reinforcement — slabs and footings — ACI 318-19 replaced the familiar 2√f'c with an equation that depends on the reinforcement ratio and carries the size effect factor λs. These sheets apply the current rule, so they will flag a footing that a pre-2019 calculation would have passed.
