Soil Bearing Capacity Formula:

To calculate soil bearing capacity, use the formula:

SBC=UBCFS\text{SBC} = \frac{\text{UBC}}{\text{FS}}SBC=FSUBC​

where:

  • SBC = Soil Bearing Capacity (lb/ft²)
  • UBC = Ultimate Bearing Capacity (lb/ft²)
  • FS = Factor of Safety

Steps to Calculate:

  1. Enter the ultimate bearing capacity (lb/ft²).
  2. Enter the factor of safety.
  3. Use the formula: SBC = UBC / FS.
  4. Obtain your soil bearing capacity by dividing the ultimate bearing capacity by the factor of safety.

Example:

Let’s calculate using the following values:

  • Ultimate Bearing Capacity = 1,000 lb/ft²
  • Factor of Safety = 2

Using the formula: SBC = UBC / FS

Soil Bearing Capacity = 1,000 / 2 = 500 lb/ft²

Input your values and use the calculator to verify your results.
