Picture a spar cap, with two truss webs attach to it. One web is vertical, and the other horizontal, since it is a box truss.
The truss is highly braced diagonally as well, so the cap has two compression web members and 5 diagonal web members all meeting at each joint of each spar cap. No matter how I design it, it seems the gussets would all get in each other's way.
I don't think metal has this problems since it has strength in all directions.
One solutions would be to make metal joints which each member can slide into. I don't like that solution because there would be lots of fabrication involved, and it might be heavy.
Could someone post a picture of wooded 3D truss with this kind of joint so I can see how they gussetted it? I'm doing lots of google image searches with no luck thus far. Attaching to anything other than the intersection would put a member into cantilever and greatly reduce its strength, I think.
