Foundation calculations - Punching shear

[eiriknor]

I get following message when calculating a foundation: "Condition not met for: Foundation punching", and then no reinforcement is calculated. I guess it shouldn`t be a problem for Robot to calculate the required reinforcement for punching in the same way it does for punching at slabs? Attached is the file.

In the same file I had to lock the dimensions or else I also got got sliding of the foundation, shouldn`t also that be fixed by Robot when Robot tries to opimize the foundation dimensions?

We wil check it.

But if you set h1=1.1m it will be ok.

That`s okay, but I don`t want the foundation to be 1,1 meter thick, then I`ll guess I get a phone from the contractor.

That's why I wrote "We will check it".

Robot does not calculate reinforcement for punching in footings.
Only pure concrete is checked for punching.
You have to calculate punching reinforcement by your own.

Okay, put it on my wishlist for later version of Robot. As I can`t get the reinforcement correct for simple bending when I have to set the thickness to 1,1 meter to get it calculated.

I think it may be just enough to switch off this verification and do it later by hand
