Hi There:
I am sizing some hip rafters for a house.
The roof is a rectangle 34 ft. x 38 ft. with four symmetric hips and a 4 ft. long ridge. It has a 12:12 pitch.
The attic floor is fully sheathed with 3/4" plywood and the rafters sit on a plate on top of the plywood.
The house location is central NC, so snow loads are not huge.
I typically design my hips as beams and support them with a post down to bearing walls. However, in this case, since the attic floor will prevent rafter spread in all directions and the roof is pretty steep, would you guys thing there is enough folded plate action going on to preclude me from having to support the hips on posts or design them as beams?
Thanks in advance.
