Will,
Very nice pictures.
It’s tough to tell from the pictures, but it appears that the roof system is a straight gable without additional support other than the eve plates. The thrust at the plates do to gravity loads would introduce the destructive tension loading. Designing to avoid tension loads do to vertical loads by use of queen posts or canted purlin plates eliminates that problem. I’ve been successful minimizing tension loading by use of those methods. It’s the lateral loads that are presenting a problem for me.
If you peg your braces, they will carry tension loads during a wind event. If you do not peg your braces than achieving a viable frame design using ‘standard’ engineering practice can be extremely difficult, at lest it has been for me.
Derek,
What type of loading is generating a 3.1k tension in the dovetail brace in your picture?
How do you engineer your frames for wind loads??
Thanks, pete
