All I am trying to understand is how the basement wall of a house can be designed to have such a small strip footing. I see you are saying the rotation is restrained and the footing can't rotate which results in the uniform bearing pressure underneath the footing. The eccentricity of the loads I...

I am trying to hit 1500 psf which is turning out to be really difficult without a really big footing. There are no other loads on the stem to help either. The floor above is essentially a slab on grade in a small open warehouse structure so I really only have the self weight of the wall.

I have the wall considered restrained at the top and bottom so the wall itself is spanning between the footing/low slab and the top slab to act as a simply supported beam. So I am not considering that the footing gets any rotation added from the soil pressure on the wall. As for the...

Can you give a diagram for what you are meaning by your comment in line 2. I am struggling to see what you mean by it. It seems like the large point load that I have labeled Ph does not have anything to resist the moment it creates.

Celt83 what you are showing is what I am referring to. In my condition the soil over the exterior portion is brand new (roughly 9 to 10ft). I also do not have a soils report and am unfortunately held to 1500 psf for my allowable bearing pressure. It just seems analyzing the footing as having...
I have a question for you all pertaining to the behavior of the bearing pressure of basement walls that are considered pinned at the top and bottom. Basement walls that I have seen are typically detailed to be supported by a strip footing that extends equally in each direction of the wall to...
