Concrete podium for steel framing

[Jonathan Monge Cubillo]

Hi all

I´m reviewing a building where we have 2 stories of concrete podium and 4 stories of ligth gage steel framing. The floor plan is like a C whith an elevator and stairs shafts in both sides.

I have a couple of questions:

1. Is it possible for the steel framing to be the main LFRS?
2. If I use the elevator shaft as the main LFRS, then is it possible to detail a proper collector for shear transfer in a concrete and steel deck cast in place floor?

Whe have done similar projects but using a concrete frame joining the shafts, generating something like a "Z" and using the steel framing just as load bearing. But I think there´s much more for the steel framing.

Thanks,

Ok...probably should have put this in the structural forum, but here we go:

1) Yes
2) Probably, but it depends.

If you need more specific answers, please provide more specific questions and information about the design.
