Frequently Asked Questions
What can this foundation calculator do?
It designs and checks spread footings and pile caps on a 2D grid layout, taking axial load with biaxial moments (P+Mx+My), and verifies soil bearing capacity, punching shear, and beam shear, shown as a 3D model.
Which standards is it designed to?
Reinforced concrete is designed to ACI 318-19, with soil pressures per the DPT (มยผ.) requirements, covering punching shear and flexure.
Is it free? Do I need to sign up?
You can lay out the grid, add footings, calculate, and view the 3D model for free right away, no login required. Exporting PDF reports is available once you sign up (7-day free trial, no commitment).
Does it support pile caps?
Yes. You can choose either spread footings or pile caps, set the number and spacing of piles, and the program distributes the load to each pile and checks the strength automatically.
Can the results be used for construction directly?
This is a preliminary design tool. The results must be reviewed and certified by a licensed engineer before being used for actual construction.
