Shed Help Needed

[RonMar]

Just remember the farther you move that cross joice up above the top of the wall, the more flex you will have of the lower ends of the rafters under roof load. This flex will show up in the form of the top of the side walls bowing outward as the weight of the roof forces downward. Since the front and rear walls will have a top caps(in tension) along their entire length they will not spread. So what you will start to see is the side walls bowing out at the top in the middle of the wall which will allow the roof peak to sag in the middle creating a swayback. I would put the ceiling joices at the top of the wall to prevent this. They will be placed in tension and will keep the walls and roof peak true. As in all structures, triangles are our friends...

Good Luck on your project.

I used cathedral ceiling design for the shed. The ridge beam is 2 x 2x12's laminated with 1/2" ply in between. This ridge beam is supported at both ends to take the roof load. On the front, the doors required that another frame of lumber be built around the door frame to take the ridge beam load.

The cross braces stiffen the side walls/ceiling.
