That glass front on the ground level floor is too pretty for that spot. Happy its being built!

Are steel stairs not typically done in wood framing?

Pretty much never. Wood shrinks over time and steel doesn't, so to use steel you have to account for it.

I wonder if being tied to the concrete elevator core helps mitigate that?

It’s not “I was in the pool!” level of shrinkage.

Not really. Connections to concrete or steel elements need to accommodate the shrinkage, not much can be done to mitigate it.

Would that create structural problems over time?

It averages 1/8" per plate, and there are 3 plates per floor (2 top and 1 bottom plate on a framed wall). 5 floors of wood framing equates to just under 2". It's not huge but can lead to sloped or warped floors. It's not a structural concern but would be noticeable.

The floors shouldn't settle where they are anchored to the concrete or steel. The stud walls will separate a bit from the floors around these structures.
That doesn't include settling. The heavy concrete elevator core could settle more than the wood frames shrinkage. I doubt this building will survive that long.
