This spreadsheet is on the bi-axial design of isolated footing using the IS method. This
bi-axial footing design can take care of both the cases of Positive and Negative pressure. This is a truly bi-axial design where both the moments and vertical force is taken care of at the same time to get their combined effect on footing design. The yellow cells are input cells. The user should not touch other cells at all. The first worksheet is to be used when positive pressure develops.
