The SkyCiv Concrete Footing Design Calculator helps engineers design foundations for footings, combined footings, concrete piles, concrete pads, and more... The software includes calculations for overturning, sliding, structural utility ratios (one-way shear, two-way shear, flexure X, and flexure Y), and more - as per AS 3600 and ACI 318. The free tool will also calculate the volume of concrete in your design.
