I really doubt this house has the steel, only has some typical sill plate staps embedded that maybe reach down two bricks. Also some gaps between the brick and block that were there during construction that indicates no tie in methods used.
Anyone have any info on this method of construction?
I know the load is spread out but this is a 2 story house and it would seem the lateral strength would be poor for shear loads.
The IRC says a pier & curtain wall can be used to support up to 2 stories. This is their photo of a pier and curtain wall:
So if I pier & curtain wall is OK on 2 stories, a full block foundation ought to be. It also says a sill plate can be a 2x4. And note that they show the sill plate with a strap embedded into the footing (which you never see).
I’d be worried about the absence of ties on that short wall. That is so unusual, I’d probably call he appropriate AHJ and speak with them before releasing that report. I’ve never seen anything like it. Looks like a change in plan…note the foundation tie in the block wall.
Frankly, I don’t know. Let us know what you conclude.
Bruce, I looked at the photo again and re-read your post and I believe what we got hear is a block foundation of 10" block and at the top course change to brick to support the sill plate for the wall and what we see is a 6" block on the inside.
The sill strap that we see is probably grouten in the 10" block below.
I have heard of this design before, but never seen it. All concrete up here.
Something to think about, because this design I am talking about exist.
Notice how the IRC diagram shows bricks tying the pier into the curtain wall.
It also shows a 2x6 sill plate, not noted in the text but the drawing size is definitely not a 2x4 since it is much larger than the double band.
The IRC diagram also shows the loading kept lower (right near the top of the foundation).
I forgot to mention that the short framed wall is leaning out some too, this has not moved, its just due to the uneven surface they put it on. I had an engineer look at a leaning short wall like that once and he signed off on it saying it would be fine. That one had a 2x6 sill though and was connected to the block.
I betcha a donut that those nails are not galvanized nor are the fastners on the OSB to the sill plate or the nails from sill to stud.
As to your original question, a 2x4 can not be used as a sill plate on a pier and curtain wall…curtain walls must also be tied to the pier in an approved fashion…with that said, how can a load bearing wall rest on a brick ledge when its not permitable with a pier and curtain wall?
I don’t think its a change in plan guys but rather the framer did not have the proper sill plate material and simply used a 2x4 instead as is evident by the excessive amount of strap that is left over…I have seen this before…I have also seen inspectors in Mecklenburg, Lincoln, Cabarrus, Stanly counties all call this out as a code violation. Again we are talking code…however with that said I would document same and advise that further evaluation of any available plans by a GC or engineer may be warranted.
