Column bearing on Styrofoam
Column bearing on Styrofoam
(OP)
Has anyone used styrofoam blocks at column locations before (See here)? I'm curious to know how you've treated this at braced frame locations (the horizontal component)?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Column bearing on Styrofoam
A few years ago when my employer went out of business I went for an interview at a DB construction company that works mostly in the food industry. They had lots of buildings that required large freezers. I asked them if they used oak blocks at the base of their columns and they said no..... they use a different material. Must have been using these types of blocks. When I asked about oak they looked at me like I was an idiot. I thought I was the only one that used this detail.

1) Prestress your anchor bolts to gain a little more friction. Reliability is an issue with this.
2) If your detailing permits it, deal with the shear in the slab on grade. The brochure seems to suggest this.
I expect that utilizing bolt bending would be tough. Would one consider the bolts to be in single or double curvature in this scenario? A gusset plate would be great but it probably undoes the wonderful thermal benefits that you're gunning for in the first place.
Whenever I encounter this thermal break business, there always seems to wind up being some bridging. The name of the game is minimizing that bridging rather than eliminating it altogether. With that in mind, I should think that it would be okay to forego the isolation at the braced columns. If 90% of your columns are thermally isolated, that's got to get you most of your energy loss benefit, right? 80/20 principle and such? I didn't do this but, in retrospect, I wish that I'd tried.
The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
