Spread Footing Analysis and Concrete Pedestal Design

Spreadsheet program written in MS-Excel for the purpose of analysis of rigid rectangular spread footings with up to 8 total piers, and for either uniaxial or biaxial resultant eccentricities. Overturning sliding, and uplift stability checks are made when applicable, and resulting gross soil bearing pressures at the four (4) corners of the footing are calculated. The maximum net soil bearing pressure is also determined.

- Individual rectangular spread footing analysis (with net pier loadings)
- Individual rectangular spread footing analysis (with breakdown of loadings)
- Multiple rectangular spread footings analysis and design (table format)
- Multiple rectangular spread footings - pier analysis (table format)

This spreadsheet assumes that the spread footing is in fact "rigid", so that the bearing pressure is distributed linearly on a homogeneous soil. (Note: the actual footing is generally not "rigid", nor is the pressure beneath it distributed linearly. However, it has been found that solutions using the assumed "rigid" concept are adequate and generally result in a conservative design.)
