Calculations
Soil Properties
Helical Pier Properties
Basics for calculation:
- Size of helix can vary - 6-14"
- Number of helices can vary to increase total bearing area. 1-3 helices per section
- Pier shaft can vary - more load capacity. Hollow pier profiles can stand more lateral loads per weight of steel pier.
- Screw force - force limit at a given radius = load bearing capacity, in the limit that we have not stripped out the soil (using a screw thread analogy)
