Additional bars not installed around opening in a flat plate
Additional bars not installed around opening in a flat plate
(OP)
Hi Everybody,
I am working on a project where the slab was poured, but no additional bars were installed around an opening.
Is there a theory that can allow you to take an effective width around/ each side of the opening and say that you can engage more of the adjacent slab bars to make up for the ones that were cut?
For example at columns you can take 1.5xtslab thickness plus the column width in that direction to be used for column effective width.
Thanks

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.

Kootk,
In your post you mention that you can "certainly" drag the bar tension to adjacent area around the opening. From experience do you have approximate width that you would feel comfortable to engage the slab on either side of the opening. The opening size is 14" wide by 32" long. There are slab bars on each side of the opening, which I can use. The additional bars were not installed only on one side.
SteynvW, see above for size of opening.
Thank you again.
