Raft Foundation Minimum Thickness
Raft Foundation Minimum Thickness
(OP)
Dear engineers,
I've been handed a plan for a raft foundation of thickness 30 cm to be executed. My question is, will a thickness of 30 cm have the rigid behavior a raft foundation is supposed to have?
Attached is a section of the foundation.
Regards

I know you hate centimeters but sadly these are the units we use here.
And yes, our company is responsible for both the design and execution of this basement.

Because the raft footing will be very flexible, the concrete in the middle of the raft won't be contributing much. The original design seems as though it would be more efficient unless you're trying to resist hydrostatic pressures etc.
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.
