Sloped joist in Simpson non-sloped hanger


I couldn't find the answer on the Simpson web site so I thought I would try here. Simpson states for a hanger like the lu26, "Joists sloped up to 1/4:12 achieve load tables", but they don't give any load reduction factors for other slopes, like 1/2:12 for example. Does anyone have any info on this, or is it just not allowed to go more than 1/4:12?

Why not just cut out a notch in the bottom of the joist so the hanger is making full contact?
Hard to say without knowing exactly what it is your trying to build.

It's just a patio cover, like a pergola but with a solid top. I'll have a ledger beam bolted to the wall, probably a 4x6 or 4x8. I can rest the rafters on the ledger if I use 4x4 or 4x6 for rafters, or use 2x6 rafters with a hanger like the LU26 or LUC26Z on the face of the ledger beam. The roof slope needs to be 1/2:12 or more to meet city code.

Simpson states that the LU26 can be used at up to 1/4:12 at the stated loads, but says nothing about a load reduction factor for a slope like 1/2:12.
