Spread Footing Size Calculator

Spread Footing Size: a planned Super Calculator tool. Covers column load. Stub page: the tool, its formula and a worked example are not published yet.

Spread Footing Size Calculator is a planned calculator in the engineering section of Super Calculator, covering structural engineering.

What this calculator will compute

Inputs: column load, allowable bearing pressure, column dimensions, concrete strength, steel grade, footing depth below grade and code.

Outputs: required plan dimensions, required thickness, punching shear check, one-way shear check, reinforcement area and spacing and bearing pressure achieved.

Formula, recorded as scope and not yet verified against a primary source: Required bearing area = service load divided by allowable soil bearing pressure. Thickness is governed by one-way and two-way (punching) shear, with punching checked on a perimeter at d/2 from the column face. Flexural reinforcement from the moment at the column face.
