The drawings are very attractive, but . . .
My boss used to tell me that the problem with computer aided design, is that it can make the work of an inexperienced engineer look really professional, once it’s all plotted out.
It easily fools the average Joe or Jill.
My very first job in engineering (1975) was drawing trusses and designing this kind of residential roof. I have to supply a little harsh criticism of some obvious mistakes shown here.
The outriggers should be twice this long.
In this situation you should hold the gable wall down far enough for the outriggers to pass over it so they will have a backspan.
Here, your barge rafter is just floating in space, and will wind up on the ground, as there is not even a continuous rim joist or ridge board to suspend it. There are other ways to do this, but this is not one of them.
In Europe, fancy brackets are popular.
That holds up the overhang.
In this view you do show a rim joist (fascia board) to hold up the tail of your barge rafter, but that’s just not enough. All of these members need a backspan, and with trusses you must also have continuous ridge blocking.
I’m not sure what’s going on here. There’s only one foot of overhang and then there’s a rafter 1 foot back from the gable wall.
So you do have a backspan on your outriggers there, but they don’t go to a truss. They just go to a rafter that is not on the 2 foot module. In this case you always wanna put your first truss two feet back from the gable wall, and leave your odd plywood spacing somewhere else in the roof where it doesn’t matter.
Folks, I haven’t had to mark up another guys drawing with a red pen since I retired in 2016. The one thing I really miss about my job is supervising the new engineers.
It’s not about busting their chops. It’s about seeing that Ah-HA! moment on their faces, when they understand something they did not previously. Everybody gets those moments and it’s a glorious thing.
EDIT: In case anybody is wondering, there’s a lot of pieces missing off of that roof plot that are never actually put on the drawings. It would be too confusing.
Things like continuous bridging, X-bracing of the trusses, and freeze blocking are only indicated by notes on the general details section of the drawings.
