Mixed Deep and Shallow Foundations for same building
Mixed Deep and Shallow Foundations for same building
(OP)
Need your thoughts, advantages, and disadvantages of utlizing deep foundations (Auger cast piles) under the core of a 12 story building and supporting the rest of the building on shallow isolated and combined footings.
Should the structural frame be designed to withstand the anticipated differential settlement?

I know it sounds good on paper and may not be practical, but may be worth a try.

What if the structure frame is continuous and it can take differential settlement up to the expected level (let say 1.5 inches)? I think that should be ok. what do you think?

Can you clarify your point?

You could draw a 1:1 projections from the top of the shallow footings near the core in the direction of the deeper footings. If you have clearance to a depth of 2B before intersecting a deep footing, you would be in good shape.
