Why do monolithic slabs have sloped footers?
Hello. I am attempting to design a monolithic slab for a garage/house project. I have researched monolithic slabs and this is the direction I want to go. But the question is: why, in every drawing and implementation of a monolithic slab, is the inner wall of the footer sloped toward the middle of the slab? Why not just a straight footer? Does this have to do with stress cracks and a better joint between footer and slab, or does it save concrete, etc? Thanks for any info!
