Basement wall with reduced bracing slab.
Basement wall with reduced bracing slab.
(OP)
Good day,
In a recent project, i had to deal with a typical basement wall extending 4 stories below ground.
The basement slabs were designed as a 300mm thick post tensioned plate.
The basement walls were designed in a separate model assuming pinned connection at the level of the slab.
Here comes the problem.
I just got a call from the contractor that he will not be able to proceed with the post tensioning for the slabs under ground.
He is proposing a hollow core one way slab with a topping of 70mm above it.
I dont believe that this 70mm will act properly as a bracing element for the basement wall
Cast in situ option is not feasible due to the large spans (9m and above).
I am looking for some suggestions.
Thank you.

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.
