Isolated Footing Against Uplift in SAFE ???
Isolated Footing Against Uplift in SAFE ???
(OP)
I am designing a isolated footing in SAFE but I am confused that how to check the footing against uplift?
Soil pressure are coming as mentioned below
Against dead load Max = -9.08 KN/m^2 and Min = -18 KN/m^2
Against wind load is Max = 53.83 KN/^m2 and Min = -38.74 Kn/m^2
footing is safe against uplift????
Footing is placed at just 200mm below FFL and tuff tile floor on the footing.

RE: Isolated Footing Against Uplift in SAFE ???
I'm assuming that you are using Winkler spring support to model the soil, If so, unless you providing tension anchors you need to change the support condition to compression only and resize the footing.

I am using the spring point support (PSPR), I am new user of this software you can explain me how we can check the footing in uplift through above values???
Thanks in advance

The CSI wiki seems to be suggesting you now need to use gap/hook elements to model tension/compression only situations by running a non-linear analysis.
