soil pressure

[curiousinvite]

What is max and min pressure?
there is positive soil pressure of 36kn/M2 , Does this means soil is in tension and I have to reconfigure my footing dimensions?

Late reply on this, but yes, positive pressure means soil in tension, which is wrong. you need to run a nonlinear static case of your full load applied to the footing. If you do so it will go in uplift on that edge and you'll see increased compression under the column. If it doesn't overturn and pressures are within allowable limits, then no need to reconfigure dimensions
