Steel Shelf Angle Thermal Break
Steel Shelf Angle Thermal Break
(OP)
6 stories, composite floors with brick clad exterior (metal stud back-up) in a cold climate. We're detailing a brick shelf angle at each floor welded to the edge pour angle and/or beam. Done this many times in the past successfully but this architect wants to have a thermal break on the edge angle so the steel inside doesn't sweat from condensation. Any thoughts are appreciated.






RE: Steel Shelf Angle Thermal Break
I've done a similar detail for beams going from outside to inside and provided an endplate moment connection with the korolath plate, but never for a brick shelf.
Maybe the bolting detail is no good because you can't use slip-critical bolts with a korolath plate (I don't think you can anyway).
Where in the detail is it transitioning from outside to inside? That is where you want the thermal break.

Thermal bridging is greatly reduced compared to fixing the angle directly to the slab edge.
RE: Steel Shelf Angle Thermal Break
I do brick cladded office buildings pretty regularly (architects in this part of the world seem to love brick), and I have never done, or seen, a thermal break between the brick shelf angle and the structure.
I think your architect is over thinkingthe problem.
RE: Steel Shelf Angle Thermal Break
Once in awhile you will have an inexperienced architect requesting a thermal break without understanding the structural ramifications. I know of no way to accomplish the thermal break without jeopardizing the structural integrity.
