Detailing and designing vertically discontinuous slab
Detailing and designing vertically discontinuous slab
(OP)
Hi to all,
I'm starting as a structural engineer and I came up with a vertically discontinuous slab, meaning that there is a wall that on it's left side is supporting a slab, and on the right side it's supporting another slab, which is about 30 cm below the level of the left side slab. I attach a JPG file.
How can I detail it to provide continuity for the slabs for both flexure and axial (diaphragm)?
I'm currently thinking on forming a tall and wide element in the interface with sufficient width for the flexure rebar to transition diagonally, and also transfer in plane forces as a strut. But I'm not convinced it is the best solution.
Have you ever encountered something similar? Any tips are welcomed.
Best regards.

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.

Thanks for your replies!
There are negative moments at the step since the beam that is formed at it is supported by walls.
Thanks for the detailing! if I understand it correctly, for this case the first one applies. What are the theoretical holes?
Regards.

1) If you ran it through the strut and tie model from the other thread, some things probably wouldn't add up.
2) In north america, we don't seem to subscribe to bar development around corners.
