Download spreadsheet for square footing design


This is an exclusive spreadsheet based program for creating the design of square footing. It is specifically designed for learner, designers, students and also teachers.

Usually, the Spreadsheet contains the following five sections.

“Input” Section of Square Footing Design Spreadsheet

In this part most of the inputs should be put in. There are other choices which can be provided in due course of time.

Only Input data in cells which contain filled background. At the position where there exist some advised values but a user prefers to modify the value for example. “Factor of safety” a default value is put in and an input place is set after “or” where necessary value can be put in and value that will be again applied is presented after “use”.

“Representation” Section of Square Footing Design Spreadsheet

The 2nd part of the spreadsheet is representation under which a diagram of the footing is presented and different types of dimension are also put in.

“Depth of Footing” Section of Square Footing Design Spreadsheet

This part demonstrates the calculations useful for obtaining the depth of footing. Both Bending moment consideration and Punching shear consideration are applied to find out it.

Generally, value computed because of punching shear consideration is lesser. Once depth is computed with punching shear consideration, an option is also available for putting the depth manually. This option is very useful if the failure is reduced by raising or minimizing the depth of the footing. Depth of the footing at the edge remains one-third the depth of footing at the face of the column that is modifiable manually in the cell by filled background.

“Steel Calculation” Section of Square Footing Design Spreadsheet

In this part estimation is made for the steel reinforcement.

“Check for shear” Section of Square Footing Design Spreadsheet

In a foundation, it is crucial to verify the safety in contrast to shear forces at both the critical section. This spreadsheet allows you to apply conditional formatting to focus on if any failure occurs in shear.
