Concreting stair and walls in one single step
Concreting stair and walls in one single step
(OP)
Hi,
Regarding the fact of concreting slabs and vertical elements at the same time, i would never recommend it because of plastic settlement which will occur.
However the contractor is asking to pour concrete a hellicoidal stair and it is landing with the adjacent walls. The walls are 3 m height and the stair isnt that big.
Do u think i will always have a settlememt problem or will it be okay for a small area ?
Thank u

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.

To be honest, I was hoping that hokie66 would show up on this one and render a verdict. Most of what I know about plastic shrinkage settlement came from him an the following documents:
CCAA
NRMCA

Where I have seen examples of plastic settlement, they have invariably been in large placements, where the quantity overtook the quality. That need not be the case for your stair.
