Footings - Allowable stress calculation error

Hi,

 

I have detected a supposed error in the allowable stress soil calculation and I need to confirm it.

 

For a single footing, in the calculation note point 1.2.3 for the analytical method and with the foloing data:

 

- Calculations according to EN1997-1 2004;

- friction degree angle: 34.9º;

- Assumption 2 where we need to divide the tg(34.9) by 1.25;

 

The calculations presented show a Nq value of 21.21. This value only depends of the friction degree angle so it must be Nq = 16.75 instead of 21.21.

Please confirm, as soon as possible, what is happening where, this is a very important verification to the footings allowable stress. See the file attached below.

 

Thank you.
