SkyCiv Concrete Footing Calculator is a free, cloud-based tool that helps engineers design isolated and combined concrete footings, pads, and piles. It performs essential stability checks such as uplift, overturning, and sliding, and calculates structural utility ratios including one-way and two-way shear, flexure, development length, and detailing. The calculator supports multiple international design codes including ACI 318, AS 3600, CSA, and Eurocode (EN). This simplified version of SkyCiv’s full Foundation Design Software allows users to input geometry, soil, material properties, and loads to generate accurate footing designs and concrete volume estimates. Engineers can upgrade to the full version for expanded functionality, including additional foundation types, unlimited loads, and detailed calculation reports.
