Combined footing problem

Fernando799 · May 22, 2025

Hello, I have a question about a foundation I'm designing. It's a combined footing with moment, shear, and axial forces.
I wanted to know if there's a biographical description that explains how the stability of this foundation is calculated against overturning.

Isn't it just first principles? I.E draw your loads and their applied locations and check for overturning about the toe of the footing. If your bracing causes uplift on one frame but compression on the other, in my mind you can count on both concurrently as the compression will help with the overturning.

The weight of the foundation multiplied by the distance from the toe of the footing to the centroid of the footing must be greater than 1.5 times the overturning moment caused by the frame. Or, you can check 0.6 times the weight of the foundation against the overturning moment.
