work examples of footings in biaxial bending to ACI 318

[Oversee]

Are there any work examples of pad footing design to resist biaxial bending based on ACI 318? I only found some simple examples from a number of textbooks.

I wish to thank you all in advance!

"Structural Concrete" 2002 edition, by N.M. Hassoun has a detailed example. That book also came with simple computer programs for RC design.

Thanks!

I received the book today, the new print in 2008.

Unfortunately, the example provided is applied for bending in one direction only. But I had solved this problem using Excel last week. Footing was considered in 100 slices and soil pressure in each slice is assumed to be constant along its thickness direction. A sum-up of the bending moment of each slice about the critical section will give Mu. In terms of the accuracy, 100 slices are acceptable.
