Thank you for the videos, they are really helpful !!! How could I consider in the uplift case the water table pressure coming from below? Could I just add a load pattern with negative pressure on the surface of the MAT, and insert a load case for non-linear (allow uplift) with 0.9DL+1WaterPressure???
When you select the center point and go to assign loads...... then after putting the values you have to must put DIMENSIONS OF COLUMN (The option punching shear area is present )..... after then you can see PUNCHING SHEAR RESULTS.

Dear sir Nonlinear analysis should be performed with respect to the lateral force like seismic force, but you don’t add EQ force & aslo load combinations.

what is the combination for uplift check as per ACI 318-08 code ? please share all the combinations with reference
Sir please explain why you selected nonlinear analysis type for uplift calculation, why you didn't select linear analysis type? Thanks.
Very nice video.. I want to when to conduct this uplift check on mat foundation?? Is it related to the ground water table?
Yes... And.. also for horizontal force

Water pressure will be =unit weight of water x height of water table.... Which will be submerged....
Apply as -ve.... In combination

@@civilmdc thanks sir if u make video on punching check in footing it better to understand and sir can make u how to anslyse finite element method
I want a video of piled raft from your end.

@@civilmdc I have seen all the videos. Design of pile cap is beautifully illustrated. But I don’t find raft on pile foundation.

Yes
You can
