Good morning

 

I m learning Robot 2011.

 

I m trying to model a raft foundation

 

would you please give me the steps?

Hi, im also new with the slab foundation and elastic ground..

I have made this model for a slab foundation, i hate a ellastic coefficient of 25Ton/m3 but i dont think i defined correctly the planar Kz since soil pressure in the result maps goes above 180 T/m2 ( According to soil study Max 25Ton/m2).

1) Can you pls tell me how to correctly define Kz (it ask for a load above foundation) and Kz=0 when i do it this way.

2) is it ok to define a kz manually since i have the value.

3)How can i see the soil pressure correctly, the moment and shear diagrams?? i have seen it in other models but cant find the panel cut tool.

Thank you for ur help.

Regards

I do not understand your model data. If you know kz = 25 T/m3 so why have you specified kz~3000 T/m3 ?

Take a look below sw of your slab is 1680 T and it gives pressure 34,46 T/m2 ; soil kz = 25 T/m3 means that if you have load of 25 T/m2 it will be displaced 1m. So in your case you get 1,34m displacement.

Yes
