Uplift could be possible in footing for many reason like hydraulic uplift pressure acts in upward direction, earthquake forces and also Larger eccentricities will also cause a portion of the footing to lift off the soil, because the soil-footing interface cannot resist tension. For a rectangular footing, this occurs when the eccentricity exceeds ek =𝑙/6 ek =b/6 This is referred to as the kern distance. Loads applied within the kern. There could be many solution of uplift like doing anchoring, dewatering, increasing SW etc but you can not use these solution because this uplift is not caused by hydraulic uplift or earthquake force. There was uplift caused eccentricity and could be controlled by giving strap beam, there are two solution you can give combined or give strap beam.

Thanks sir for guidence
Thank you So much.
Sir,what was the price of this Course?
there is uplift in your design which is not acceptable as EARTHQUAKE CODE and the strap beam is not the solution for this situation
