Steel Frame/Steel Studs Lateral Resistance

[RareBugTX]

Hello all. Does anyone know of a resource (building desing example) where there is a metal frame to support gravity, but where the lateral resistance to wind (controls) is provided by steel stud infill walls.

Your leads will be appreciated

It would be easiest to frame the stud wall tight to the underside of the steel beam, and attach it as required to take the shearwall shear. The steel beam will really be doing nothing for gravity loads, and the studs will need to be designed for the gravity loads.

There are slip tracks with vertical slotted holes available, which would be another option. Then the steel beam WOULD take the gravity load.

I designed a one story building once where I had tube columns aligned with a stud wall and ran flat bar X bracing on each side of the tube columns (and wall studs). I, then, used horizontal furring channels between the X bracing to fasten the gyp without "bumps" showing thru the wall at the bracing locations.

Based on my experience, unless the lateral loads are rather small (sheathing can be used to resist) I would recommend using the steel as both gravity and lateral. Most of the times a steel braced frame system is more cost effective than using metal studs with x-bracing.

I don't think I was very clear on the system that I decribed. This was a steel frame which resisted both gravity and lateral forces but we arranged it in such a way to fit with the steel stud wall.

There are a lot of buildings going up here in Chicago where you see the steel frame put up with only shear connections. At a later construction stage, the backing steel studs walls are built and face brick is supported on them.
A note on this type of structural system is that the cold formed stud walls infill the steel frames. That was the original reason for my question, since I was concerned about the appropiate connections and details between the studs and the steel frame.
