ASCE 7-22 Cl. 1.5.2 addresses buildings with independent structural systems with multiple Risk Categories. It also states that if portions of a higher Risk Category area pass through a lower Risk Category area and depend on structural elements within the lower Risk Category area, that those elements are to be designed to the higher Risk Category as well.

I'm looking for confirmation that this same logic also applies to a situation where structural elements like concrete cores that are part of the SFRS and columns supporting gravity loads in a higher Risk Category area support a lower Risk Category area’s structure above. The system would be non-independent, with the SFRS core and column lines running continuously from a higher Risk Category area in the lower part of the structure to a lower Risk Category area in the higher part. 

If this is permissible, I would think that the structural elements in the lower Risk Category above can be designed to lower demands with regards to Importance Factors, drift requirements, SFRS detailing and system choice, redundancy, and performance objectives, and anything else in ASCE 7-22 I may have missed at this point, as long as the function of the higher risk area is not put at risk by the performance of the lower Risk Category area’s structure in an extreme event (or during normal service life if applicable).

Thank you for your thoughts. I'd also be happy to know if there are any additional resources or design cases on this subject.
