I have a question regarding the service combination 7a on 2.4.1 which is 0.6D + 0.6W with having uplift pressure forces on the raft due to water table I will add H which will end the load combination in 0.6D + 0.6W + 1 Uplift .My question is should I change the load combination to be 0.9 OW +...
So basically I have now tension on my raft due to this load combination, so I was trying to find an alternative of using tension piles,so I was hoping that there's any structural background on increasing the 0.6D to be 1D or decreasing the 1H to be 0.6H
I think the code meant fluid loads - Where fluid loads F are present, they shall be included in combinations 1a through 6a - but it also stated the H after and said that it should have a factor of 1 if its will add to the principal load effect, which is more critical to take its factor as 1 also...
Using ASCE7 22 when applying the service combination 7a on 2.4.1 which is 0.6D + 0.6W with having uplift pressure forces on the raft I will add H which will end the load combination in 0.6D + 0.6W + 1 Uplift.
My question is, is this load combination is logic or adding the uplift with factor 1 is...
