Eurocode safety factors for Heave and Water

[smonver]

Hi,

For one of my under ground box Raft Design I want to use EC0 equation 6.10. I have tried to go through EC7 to get the "gama f" value for Heave but was not able to find it, I think it would be same as for other variable load i.e. 1.5. Further more when I want to make the Heave as accompanying variable with leading variable of Wind or Live load for that I need the gama 0 , gama 1 , gama 2 values but could not find it either. Can anyone please let me know where I can find it or what values should I use.

I intend to use following combination for ULS Case, here the bold value represents the leading variable and I am looking for gama0 value in red. I would also appreciate to hear any comments you have for the load combination. Can you please also confirm that we need to use 0.9 for dead as per UK A.NA.17 for load combination 5 to 10.

1-1.35xDead
2-1.35xDead+1.5Live
3-1.35xDead+1.5xLive+/- gama0x1.5xWind
4-1.35xDead+1.5xWind+ gama0x1.5xLive
5-0.9xDead+1.5xWater as per A.NA.17 Live=0
6-0.9xDead+1.5xHeave as per A.NA.17 Live=0
7-0.9xDead+1.5xLive+/- gama0x1.5xWind+ gama0 x 1.5xWater
8-0.9xDead+1.5xLive+/- gama0x1.5xWind+ gama0 x 1.5xHeave
9-0.9xDead+ gama0x1.5xLive+/-x1.5xWind+ gama0 x 1.5xWater
10-0.9xDead+ gama0 x1.5xLive+/-1.5xWind+ gama0 x 1.5xWater

And for SLS case I need the gama 2 value for the Heave as well to be use in equation 6.16b of EC0.

Hope someone will be able to advise me for the above Eurocode safety factors.

Regards,
