Combination of Heave and Water Pressure
Combination of Heave and Water Pressure
(OP)
I am designing a building with 6 basement and as it is low rise we have to go for raft.
As there is heave pressure along with a water head of 22.5m I am not sure that whether in floatation check I have to include both heave and water pressure or one at a time.
Similarly in Service and Ultimate load case I have to consider both together or sepratly. It would also be helpfull if anyone can define Load combination for both SLS and ULS.

The raft must be sized so that the dead weight of the building plus raft exceeds the weight of displaced water. Then, of course, the raft must be reinforced for uplift pressure of 22.5m of water...wow!
