Perhaps the sketch attached earlier is not a good example - it is just indicative. The detail is actually for 4 bolt arrangement on each rafter, with beefier bolts, and the plate will be continuous with no joints. For the plate at least the maths does work, however I see that practically it will...
Thanks for all the comments guys. Really appreciated. I will take these points on board. Few things that I was not clear about. The design is to cater for dead, live and low wind loads only, no snow loads. The moment plate has a 8 bolt arrangement, not the 6 shown. My first option was to put a...
Thanks for the input dhengr. Appreciated. There is always a better way to put your opinion across. For your information, I have also thought about this thrust and how to address it earlier. Strengthen the top plate in the horizontal direction, and tie it back to the transverse end walls (or...
dhengr - Perhaps rather then being so negative and demoralising, you can be a bit more of a help. This design is just a thought at this stage, in relation to what I have seen out there (yes I have seen these connections at work, and the roof is not collapsing!) It is an opportunity to be...
Mike, so with collar ties, my understanding is that its purpose is to prevent the rafters from pulling away from the ridge beam/board (if one was installed. That is what I am trying to (partially) achieve with the moment plate. Correct me if I'm wrong.

Hi There
I have a design where the owners require a slanted ceiling (rather than a flat ceiling). The span between walls is 26' (rafter span will be 13'). I have designed the rafters to be 2x8 @ 50", connected at the apex using moment plates either side of the rafters (to prevent sag/creep). By...
