You were right, the old document used service loads, while the newer document used the factored load.
What confused me is ACI350, where in chapter 9 it discusses the load combinations and load factor, and then limits the stress to fs. I dont know if I should go with fs, or 0.9fy?
Hello All
I was going through the PCA circular tank design, and I noticed it calculates the ring steel by dividing by 0.9fy, while in some other places, it states that the steel stress should not exceed a specific value fs (20ksi for grade 60 steel and 14ksi for grade 40 steel). does anybody...
