Rectangular footing eccentric pressure, one axis

Helper calculation of eccentricity from moment and vertical load; it is not code-based design or capacity verification.

Helper calculation of average pressure as vertical load divided by area; it is not code-based design or soil capacity.

Calculates four corner pressure combinations for a rectangular footing with two-axis moments.

Calculates simple strip foundation volume from length, width, and depth.

Calculates indicative pile capacity from user-supplied base resistance, shaft resistance, and safety factor.

Calculates simple average soil pressure as load divided by base area.
