Thank you all for the quick responses! Sounds like the boundary elements are what I should be focusing on, and the middle portion of the shear wall footing just needs to be thick/stiff enough to receive the sill plate anchorage and assist with sliding resistance, but not really the overturning...
Any input on methodology for designing footings for wood shear walls? Typically I've seen the walls supported by a thickened slab, but is there a way to quantify the width needed for a given soil bearing (assuming it is NOT carrying gravity loads)? Alternatively, if we use spread footings at...
