But if I use LRFD what would the phi factor for uplift be? (The equivalent to phi = 0.9 for a beam using 1.2D+1.6L). For ASD, is it 0.6D (down) > 0.6W (up) or 0.6W/0.6D < 1.0. Is it the same for LRDF - 1.0W/0.9D < 1.0? Should the 1.0 be 1.2 or 1.5 in either ASD or LRFD?

ACI changes the load factor for F and H depending if F or H are driving or resisting forces but says nothing about phi.

Thanks
