Vaulted Hip Roof

[XR250]

Got an 18x18 ft. carport with a pyramid, vaulted hip roof. I am showing a dogleg W8x24 beam to support the 1 3/4” LVL hips. Trying to create a clean detail for attaching the hips to the beam. I am thinking welding a 1/4” backing plate to the beam flanges and then plug welding a Simpson HRC1.81 to the plate. Anyone got any better ideas?

Thanks!

If you want to go bargain basement on this -- and I know that you do -- I suppose that you could weld a face mount Simpson hanger horizontal to the cap plate and call it good. You might need to supplement uplift capacity but that's easy enough.

Don't necessarily want bargain basement - just clean and easy - which the Simpson idea is. Thanks!

I honestly don't worry too much about uplift on these hips. For short term loading, the roof diaphragm will tend to distribute the load to all the rafters so I have alot of little connections helping.

I was thinking about switching to dbl. 2x8's for the hips as they will fit in the rafter space better.

How are you planning on fastening the 2x10 roof joists to the double 2x8 hips? I usually spec hip beams/boards at least 2" deeper than the rafters/joists. I'm curious how you would do this for fastening? Top mount hangers?

The rafters are spanning 9 ft. max. so just toenails. This is a pretty common connection in our area even for 18 ft. span rafters and I have yet to witness an issue with it.

@XR250,
What purpose is served by the kinked steel beam?

BA,

It was to support the hip rafters before the idea was thrown out by dhengr to rely on resisting the hip thrust by the tie beams.

XR250,
Okay, thanks. I should have read it more carefully.
