matt foundation

[pmtrevisan]

hello knowledgeable group. All the literature that I have found so far regarding matt foundation is for columns supporting slabs. I have a situation where there are no columns. We are re-designing a 1 way floor system 20+ stories, with walls (slab supported by walls). Openings for walls at the corridor, and interior units.
My question is how can I use what I've learned thus far (school, experience, and books) to design a matt foundation for this case.
For the situation of columns its relatively simple (supporting loads). do I break the wall up into infinitessimal elements and design it for 1' sections....

Any help would be appreciated.

Looking forward to your replies.

Ask yourself the following question. If the mat under consideration was a floor supported by walls, and the floor was subject to a uniformly varying load, how would you analyze it? If you can answer this question then you can easily analyze your foundation mat since the analysis would be virtually identical.

Agreed, I was hoping that there would be an easier straight forward approach.

Thanks for your insight, it is much appreciated.
