Bending on Anchor Rods
Bending on Anchor Rods
(OP)
I am doing an addition to a freezer facility. As part of providing a continuous thermal barrier. The insulation sub-contractor wants to put a 5" deep high density block under the column base plates. Where I have x-braces, this would put the bolts in bending.
Does anyone have any good ideas on how to transfer this lateral load (from wind) into the foundation without putting the bolts into bending?

Never, but never question engineer's judgement

This is not an option.
There are several problems that come up that can be handled that way.
This situation I am working as a problem solver with a team and not on an island providing a service.

Is there a slab?
Even with the 5" below the baseplate, you still get conductivity through the bolts, right?
How big are the bolts?
Maybe the previous idea would provide similar thermal break?
With 5" offset, I can't see any simple way to avoid designing for bolt bending. You could put plate stock between them on egde, but then you may as well just extend the column down.
Any idea how it was done on the existing facility?
Hope my comments aren't too scattered, just thinking "out loud".

I am goin gto look at putting the column on the concrete pier.
Any steel that is in the slab or in contact with the floor insulation has to be insulated.

Utility structures and Highway structures are often built with the distance from the top of concrete to the bottom of the base plate equal to two to three bolt diameters.

If they are willing to accept these then maybe they would be willing to accept a tube section welded to the underside of the base plate and embedded into a grouted hole. This takes out shear only.
