2D model or 3D model
2D model or 3D model
(OP)
Hi, I posted this thread in foundation section but no help there. I think its pretty basic question about modeling so im posting it here too.
Heres the question - if we want to calculate contact pressures under foundation, which model is more accurate/better 2D or 3D? SEE ATTACHED FILE.
I think plane - 2 d model has too conservative results (because it doesnt count the contribution/effect of other foundation nearby?)
I like 3D model better. Is it OK? How do you guys calculate this?
tnx for answers.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Good little comparison exercise though.

In 3d model you have a rigid structure, so load distributes between all walls based on stiffness and load location. So basically load from inner walls gets distributed to outer foundations.
There is no stress distribution between foundations because of the soil - I think you where asking this. It is only distribution because of the structure itself, not soil.
