Strip Foundation with Uniformly Distributed Load Offset from Point of Interest

Notation and Units

Metric and Imperial Units

The above formulas may be used with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout with examples of units which should be adopted listed below:


  • B = width of foundation, ft or m
  • q = load per unit area, kip/ft2 or kN/m2
  • x = horizontal distance to point of interest from edge of load, ft or m
  • z = vertical distance from load to point of interest, ft or m
  • α & β = angle of interest, degrees
  • ∆σ = stress increase at point of interest, kip/ft2 or kPa
