Foundation Design and LLR
Foundation Design and LLR
(OP)
I don’t really work with many projects where I can take LLR. I have a project where it is possible and at my column base I have reaction of
Dead=75
Live = 35 (includes LLR)
Snow = 15
So, to design the foundation in accordance with equate 16-10 of IBC2009 I would use 1.0D + 0.75 L + 0.75 S = 113 kips.
Just want to make sure this is correct.

I see the load combination as saying: if there's a huge blizzard, you won't be having a party at the same time.
I wouldn't hesitate to utilize both reductions.

Your combinations to check are:
2) D + L = 75 + 35 = 110
4) D + 0.75L + 0.75S = 75 + 0.75(35) + 0.75(15) = 112.5
