Wood framing inside a manufactured steel building

Wood framing inside a manufactured steel building

Wood framing inside a manufactured steel building

I am designing a 2 story wood dwelling inside of a steel building which was not designed to carry any gravity or lateral load from my light frame wood substructure. Unless I can figure out how to show that there are no loads or interactions that affect the steel building, the AHJ has said that I have to analyze story drift and there may not be any tight or incidental contact between my wood and the steel. I could put my outer walls inside of the steel columns, wasting an annular space of almost 2'. But I am still puzzled by how to negate interaction of out-of-plane forces from the contact at the "tunnels" to each door and window. Some kind of flexible connection? Anyone else deal with this? Guidance would be appreciated.

RE: Wood framing inside a manufactured steel building

You haven't given any indication of the amount of movement you have to accommodate, but if you're talking basically about "dormers" for the doors and windows, if you can configure the tunnels so that a wood trim covers the drywall at some point (wood trim fastened only to one side of the joint), it's easy enough to make a sliding joint that will disguise the movement.
