A Picture's Worth 1,000 Words

A Picture's Worth 1,000 Words

RE: A Picture's Worth 1,000 Words

I'm impressed at how round that hole is. The guy doing the cutting should be commended..

Are those your scribbles showing what appears to be lintel angle locations? or did one of them at least indicate they feel something should be there.

RE: A Picture's Worth 1,000 Words

I betcha that it works. It's either a channel or an 'I' beam of sorts. Support is on the upper flange to an "arch" below.

RE: A Picture's Worth 1,000 Words

Best part is the waterline clash. Maybe shave the deck soffit to make the duct fit over top ;)

RE: A Picture's Worth 1,000 Words

At least there's a grouted cell at the beam.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

(OP)
jayrod... the scribbles were an initial thought of how to remedy the situation.

I haven't spoken to the site foreman yet, but, my current thought is to fill the (round) hole with CMU and cut a new hole to the left. Hopefully there will be a dropped ceiling to cover this up!

oldestguy... do you think this would still work 5 months from now? We're in Wisconsin. In addition, can you notice the slight high-low condition in the zoomed-in photo?

RE: A Picture's Worth 1,000 Words

Those look like cold formed zee or cee members. One approach could be to bolt a 3' length of channel to the wall beside the hole and cantilever out a bit to pick up the light gauge framing with a clip angle and some Tek screws. Might be cheaper than cutting a new hole and bringing a mason out there.

One more thought about why it is OK as is. Chances are the original design had that section as a simple beam supporting a slab. If one considers the section -slab combination as a single structural member, the section is mainly in tension and the slab is in compression. Result is that much of the reaction load on the wall is via the slab, not the section. If the support of the section is taken away, the slab takes over.

I thought the framing was cold-formed C sections with steel roof decking. Photo may be deceptive.

This looks like a PEMB with masonry infill walls. Presumably these are not load bearing masonry walls.

RE: A Picture's Worth 1,000 Words

This does look like a PEMB, but that wall *is* loadbearing, at least for the heavy gauge CFS joist that sat on the filled core the contractor has cut out with the round hole... Look at the member at the round hole: it doesn't continue. This is the end of the beam, on the swiss cheese wall.

Now I see it. =8-0

Grout in a thick rigid pipe "duct" section through the wall?
