What kind of roof system is this?
(OP)
Wondering if anyone here can ID this roof system and the manufacturer. It looks like a space frame system to me but not sure since the top members are only running in 1 direction. In typical space frames that I have seen, they normally run in both directions.
The girders are at 40' o.c. (top and bottom made out of WT sections) while the joists (red iron that looks like hat channels) are at 5'-0" o.c. (running from girder to girder) then steel deck on top. The building is at least 30+ years old located in the Southwest US.
Thanks a bunch!

The good thing is that Butler is still around so hopefully I might be able to get some info but the system is no longer in their catalog. I'll give them a call right now.

What I'm looking at right now indicates a 34 psf total live plus dead load design level for a 40' space truss. Keep in mind that the design is based on AISI Cold-Form provisions from back in the mid 70's. Like every other design spec around, requirements have gotten more stringent over the years so there may not be quite that much capacity if checked to today's codes.

In addition to an edit function, it would be nice if there was a way to take a discussion private on this forum so that one could pass email addresses and phone numbers around one-on-one when appropriate.
